At times like these, the spirit of mankind is affected in a most fundamental way and we have a responsibility to

respond to that critical requirement.

So we therefore seek a design to make this a very special place. The new hospital needs to be clean and bright and fit for the purpose for which it is to be used. That must be taken as read - but more than that it needs to support and stimulate the spirit of those who are treated and those who give that care.

Good design is neither an add-on nor a luxury. Nor is it an expression of the style of the decade in which it is built. Good design happens when the building meets all the functional needs yet, in use, turns out to be robust, eminently flexible and adaptable to changing times and at the same time, have the power to provide inspiration to those who pass through it and work in it. It is the responsibility of the design team to achieve these demands in what is likely to be one of the biggest investments in the health service in this area.

Having set ourselves such a significant objective, we need to make sure that it can be delivered.

We need to ensure that, at all stages of the process, design is taken seriously. How will we achieve this? How will it occur? How will we know when it happens? How will we know we are successful at the end?

We need to listen as well as to talk.

The key to a successful design process is the involvement of not only the clinicians, the technicians and the support specialists, but must also include the views of patients, their families and friends and all those who use the buildings. For if we do not listen we will never move beyond replicating the same mistakes our previous generations have made.

We believe that a well designed hospital will help patients recover their health and spirit. A well designed hospital will provide a pleasant working environment for our staff. A well designed hospital will also bring communities together and engender civic pride. It is this vision that the Trust now aspires to achieve.

Geographical Context Pembury Hospital is located in the heart of the Kentish countryside. The area within which the site falls is characterised by undulating topography and a number of ridge lines. The site lies immediately to the south-east of three ridgelines. The site is situated between two conurbations

, the major town of Tunbridge Wells and the village of Pembury itself. The village has a population of 6000 and is mainly made up of domestic housing with a few village shops. There is very little space for expansion within the village development boundaries.

The town of Tunbridge Wells is a major Kentish town with a population of 104,000 and is a mixture of domestic housing, retail offices with some out of town retail and industrial areas, one of which lies to the northeast of the hospital site.

Site Set in Context of Area The Pembury Hospital site comprises approximately 14.1 hectares and is situated within the Metropolitan Green Belt area. It is surrounded by, but excluded from, the High Weald Area of Outstanding Natural Beauty (AONB) and the Pembury Walks Site of Nature Conservation Interest (SNCI) to the north. (The AONB is a nationally important landscape designation and the SNCI is noted for a large number of protected species, (hazel coppice and heathland.)

The site is also surrounded by the Kent Special Landscape Area. There are three Sites of Special Scientific Interest (SSSI) located between 55 and 100 metres to the west and northwest of the site Therefore any development has to be sympathetic to the landscape and ecological constraints of the locality.

Pembury Hospital Site

The Pembury site, while being in the Green Belt, provides a number of unique development opportunities created by the sloping nature of the site, the location and surrounding environment. Open views to the site are generally restricted by the topography and the heavily wooded character of the area.

The site slopes from west to east and north to south and is terraced at the mid point where the site is effectively spilt by the main hospital road running through its length. Although this produces some restrictions it also provides a number of opportunities to produce design innovation.

Most of the site is developed at the present time and planning permission has been approved to develop to a similar footprint. However there is one area marked in yellow, at the south eastern edge of the site, that has been designated outside the development boundary to ensure that the site retains its synergy with the surrounding area.

The site will continue to function during the development and while this does influence the solution, the fact that the site is effectively split in to upper and lower halves it does provide scope for the construction to take place with the minimum of disruption to services.

Design Review

Scheme Overview The nature of NHS healthcare provision in the Maidstone and Tunbridge Wells area underwent comprehensive restructuring in April 2000, when the Kent & Sussex Weald Trust merged with Mid Kent Healthcare Trust to form the Maidstone & Tunbridge Wells NHS Trust (MTWT). The newly formed Trust consists of three hospitals: ■

Maidstone Hospital

■

Kent and Sussex Hospital (Tunbridge Wells)

■

Pembury Hospital (Tunbridge Wells)

The Trust’s audit of healthcare services identified a need for wholesale restructuring of services, and the introduction of additional services; and the current inefficiency of the three hospitals in being able to provide an integrated service. It was concluded that site rationalisation should take place and that there should be one general hospital in Tunbridge Wells (rather than two, Kent & Sussex and Pembury) and one general hospital at Maidstone. The Trust’s proposals for a rationalisation of the Pembury site are based on a ‘Hub and Spoke model’. The ‘Hub and Spoke’ Model of Care seeks to balance the advantages of centralised specialist provision for the minority of patients who have acute needs, with the needs of the majority of patients who can be treated locally on a routine basis. The hub would be located where the specialty would be based, whilst the spoke would contain outreach services to the other site.

The proposed development for a 595 bed District General Hospital Service for the wider health community, is for the provision of the complete range of Secondary care services (i.e. District General Hospital) including Accident & Emergency, Air Ambulance provision, Diagnostic & Treatment Centre, as well as a Community and Mental Health Service. The development is planned in collaboration with the Primary Care Trust, and will provide new and modern facilities to: ■

Improve the clinical quality of services by reducing split site working in Tunbridge Wells, ensuring sufficient capacity at Maidstone and Tunbridge Wells, minimising

clinical risk, allowing sufficient critical mass of clinicians and patients, improving functional relationship, eliminating obsolete buildings and equipment.

■

To improve the environmental quality of the services eliminating facilities that do not meet requirements of security, good patient managment, privacy and dignity

(including single sex accommodation) or disabled access and facilities, minimising travel between services- i.e: to provide a modern, appropriate, patient focused, healing and caring environments.

Brief Outline History of Trust Site In 1834, two acres of land was purchased in order to build a Workhouse and Infirmary.

These were built in 1836 and are now used as the Trust HQ. In 1838 the site became known as the County Hospital and in 1870 the chapel was built. In 1885 a 6-year building programme commenced, followed by further building works in the 1920’s and 30’s. In 1940 a number of temporary buildings, were constructed to accommodate the increase in casualties from the Second World War. These are still used as patient accommodation today. The last new building to be constructed was the Women’s Ante-Natal Clinic in 1987.

Although the Pembury site is used for acute patient services, these are restricted to Care of the Elderly, Acute and Rehabilitation, Obstetrics and Gynaecology. There is also a large Radiology unit comprising Nuclear Medicine, MRI and Computerised Tomography Scanning.

Acute Mental Health Care is provided on site.

None of the buildings on the site are listed or under any type of protected status.

Due to it’s current physical and operational condition, a new model is required to meet the needs of patients, visitors and staff as outlined in the NHS plan.

Existing Site Occupation & Usage The site is currently occupied by a 243-bedded acute hospital and 42 acute mental health beds managed by West Kent NHS and Social Trust, with associated staff accommodation and car-parking. Many of the buildings on the site are over 59 years old and some more than 100 years old. Direct access and egress to and from the site is achieved via Tonbridge Road on the Southern boundary of the site.

The topography of the site is characterised by a south-east facing slope. The highest point at the crest of the slope is at approximately 120 metres (AOD), and at the lowest point of the site is at approximately 85 metres (AOD). The highest point of the tallest building on the site (the maternity building) is approximately 137.6 metres (AOD).

Public Sector Comparator Design Options: Acute Hospital The Trust asked its Technical Advisors to produce a number of options from which it could

choose a preferred design for the Public Sector Comparator. The advisors produced seven draft designs and these were presented for consideration at a workshop. The various options were

Mental Health Unit

discussed and from these discussions a PSC design was chosen. All seven options are described below.

Option 1 This is a conventional nucleus type plan configuration with two parallel wings linked by cross wings enclosing a central atrium. The wings are set at different levels following the slope of the site and are generally six storeys high.

This option was selected for the shortlist of three but although this plan arrangement is a well tested layout it was felt that it created a rather monolithic shape on this site, and it was less sympathetic to the crossfall from the road down to the tree line and was therefore not elected as the preferred option.

Acute Hospital

Mental Health Unit

Option 2 This is a series of five L-shaped blocks set at irregular angles to each other to help reduce the impact of the size of the buildings on the site. The horizontal leg of the L is two 15m wide wings separated by a 10m hospital street / atrium, with the vertical leg being 15m wide following the slope of the site.

It was felt that the overall plan was too fragmented and that the vertical leg of the L-shape was too isolated to permit the creation of good departmental relationships. This option was rejected at the outset.

Design Review

Public Sector Comparator Design Options: Acute Hospital Acute Hospital

Mental Health Unit

Option 3 This is a series of six C-shaped courtyard blocks linked in a step arrangement on plan and separated into two groups of three by a central entrance wing. As with Option 2, the configuration is designed to minimise the impact of the size of the hospital. The higher and lower wings each contained a hospital street linked by a cross wing.

This was rejected because the larger number of blocks (6 No.) would make it difficult to provide sensible and adequate departmental spaces without excess fragmentation and that the two hospital streets required by the design will cause lack of clarity to the building complex.

Acute Hospital

Mental Health Unit

Option 4 This is developed to try to optimise the south east facing slope in that it explores the opportunity to step the building with slope, and consider the benefit of the south easterly aspect being used for useful solar gain. It comprises four blocks linked by staircase towers, with a hospital street separating two wings, one of 15 m width and the other of 20m. From the 20 m wing two 15 m wings run at right angles, stepping down the site and enclosing an atrium with a 45° glazed roof rising the full six storeys of the building. The glazed roof was subsequently removed as part of a cost engineering exercise.

Because of its advantages over the other concepts, Option 4 was shortlisted and selected finally as the basis for the PSC.

Public Sector Comparator Design Options: Acute Hospital

Mental Health Unit

Option 5 This is podium and tower concept considered to minimise the footprint of the building on the site. The three-storey podium is necessary to provide adequate space for Accident and Emergency and Diagnostic and Treatment Centre (DTC), with the tower containing the wards.

It was considered that the impact of a 15 storey high building would not be acceptable to the Local Authority or the community.

Options 6 & 7 Acute Hospital

These are similar and are designed to try to keep the height of the building down to a minimum.

They are effectively large and wide plan forms, pierced by light-wells where possible to try to introduce daylight to the deep central spaces.

These were rejected because although the wide and deep plan forms produce flexibility in planning the various departments the same plan form severely limits the amount of natural daylight which would reach many of the spaces, and would place a high emphasis on artificial ventilation.

The layout of the site makes it difficult to provide a secure environment for patients, visitors and staff. Buildings sprawl over a sloping site with long distances between departments. There are a large number of entry points, complex road infrastructures and long internal travel distances.

Access to the site is poor because the facilities are overcrowded. The current accommodation is dispersed with staff, facilities, wards and accommodation located in no logical order. Split site working causes delays, disruption and communication problems. The proposals outlined

Clinical Model of Care Emergency Care Pathway

DTC / Theatres

Women & Children

The model of care developed for the original Outline Business Case proposed a “hub and spoke” service configuration between two District General Hospitals at Maidstone and Tunbridge Wells. The specific configuration of the “hub and spoke” was agreed through public consultation.

The model identified three broad categories of care process : ■

Elective care

■

Unscheduled care

■

Rehabilitation, discharge and continuing care

Care principles and outline process flows were established in each of these categories, while service configuration was based on the existing specialty / care group arrangements within the Trust.

The PSC design has been developed to reflect the best understanding of how these processes and principles would be reflected into practice.

Design Development of Clinical Model of Care

Since the Public Sector Comparator of early 2002 (submitted to the Local Planning Authority for Hospital Redevelopment), a more detailed clinical planning brief for the facility has been developed within the Trust.

Further to the original Outline Business Case, the Trust established a process for ensuring focussed clinical involvement in the development of the detailed design briefing / specification material for the project. This process has included the review of the outline model of care in light of the national modernisation agenda and the development of clinical “best practice” both nationally and internationally.

This has resulted in a more detailed model of care having been agreed, supported by a full range of operational design policies for clinical services. The outline care principles have been refined and are now supported by detailed care principles for each service area.

The model of care is based on the principle of Graduated Care – the grouping of patients based on their level of clinical dependency / need rather than on the basis of specialty or service arrangement. The model identifies 3 care processes and the principle of graduation will be applied within each of these : ■

Emergency Care

■

Planned Care

■

Women & Children’s Care

Each of the care processes is supported by clinical diagnostics and other clinical support services.

Design Development of Clinical Model of Care

Detailed patient process flows have been identified throughout. Based on these, a comprehensive set of adjacency requirements have been developed with the intention of maximising the effectiveness of patient journeys and minimising the mixing of flows within the design solution. The intention is to separate the flow of patients, staff, visitors and supplies within the facilities.

The Public Sector Comparator has been tested against the more detailed design brief and is being updated accordingly in design development. In order to accommodate revised spatial configurations, each ward block has expanded in width to allow as much bed space as possible to face south east, with administration and shared spaces located adjacent to the internal atria. The continuous 10m wide street / atrium becomes a series of wider atria within each block linked by a hospital street. The stepped profiles of the south-east face of the hospital are reduced.

The patient / staff diagram illustrates movement within the buildings between departments and particularly focuses on the location of theatres.

Thus the design process continues to Design Review 2, to the bidding teams and eventually to construction.

Site Overview: Landscaping & Phasing The topography of the site is characterised by a south - east facing slope. The highest point at the crest of the slope is 120 metres (AOD), and the lowest is 85 metres (AOD) The highest point of the tallest building on site (the maternity building) is 137.6 metres (AOD).

The site is effectively terraced along the line of the internal service road where the ground drops by approximately 4 metres, dividing the site into upper and lower levels.

The site sits within the Green Belt and while this does bring some restrictions it does provide

3 3

some wonderful opportunities for development.

There are a number of existing green areas within the site and it is proposed that, to a large extent, these will be retained and enhanced.

2

Zone 1, Valley Woodland

4

The strategy for this area will include the retention and enhancement of the existing woodland to improve visual as well as ecological character. Woodland glades will promote natural ground flora and a woodland walk an amenity for staff, patients and visitors.

2

2

Zone 2, Lower section of site Any loss of vegetation may be mitigated by tree and shrub planting to integrate the new hospital into the overall landscape. The existing hedge along the Tonbridge Road boundary will be retained and enhanced by additional trees to help screen the hospital from close and middle distance views. The Mental Health Unit will have specialist gardens and courtyards.

Zone 3, Upper section of site

Where possible mature best quality trees will be retained and any loss will be replaced by the planting of semi-mature trees. Planting on the roof of the multi level car park will help to screen vehicles and soften the facades. The area to the west of the car park can be grassed and used as an amenity area for staff, visitors and patients.

Zone 4, Internal Woodland Some new planting will enhance the visual and ecological nature of an area which is already ‘wild’ in character. The proposals will include the provisions of bird and bat boxes to encourage wildlife.

Mental Health Unit The Site The Mental Health Unit is an integral part of the PFI and it is proposed that patients will use the DGH facilities for acute medical treatment.

Support services will be provided from the DGH, i.e: catering so its location within a reasonable distance is important.

In the original option (see pages 15-17), the Mental Health Unit was designed as a traditional modern facility with separate wings for elderly and acute patients. The unit was located to the front of the hospital in all 7 options. However after some discussion it was agreed that this location would not provide the correct setting for the patients as it was too near to the internal and external roads and could possibly be detrimental to patients who need space 3

and tranquillity. It was therefore agreed to relocate the unit to the rear of the site (see drawing opposite).

The unit will provide 26 adult inpatient beds, 4 intensive care beds, 29 older people’s inpatient beds, a 13 place older people’s day centre and house the older people’s CMHT staff for the locality.

2

There were a number of design parameters placed on the design of the building: ■

Patient accommodation should be at ground level

■

The building should be of domestic scale

■

There should be abundant natural light in the inner spaces

■

Provision of secure gardens within the design.

Mental Health Unit Site Constraints & Planning Requirements 1. Concentration of Hub, Administration, Reception and Assessment for easy access to adjacent wards.

2. Adjacency of Assessment Units to PICU, access for police vehicles.

3. All wards and other elderly facilities at a single level - significant considering topography of site.

4. Privacy between Bed-areas vis-a-vis Male / Female and Adult / Elderly.

5. Staff observation of wards - Bedrooms and Day Suites clearly visible from pivot point.

6. Division of wards by sex or medical condition.

7. Access for emergency vehicles and requirements of HTM 81 and Fire Service.

8. Floor to floor heights in relation to site topography, mechanical services, and limited scope of site engineering.

Option 1 This design was single storey and based on a number of wings which contained the wards with a central service core which contained the common and service areas. The secure open spaces would be between the wings. See drawing below.

Option 2 This design is two storey with an additional upper level over half the site area. The main ward areas are split by a central core where the administration and service areas are contained. There are four gardens which provide secure open spaces. See drawing opposite.

Design Review

Mental Health Unit The Chosen Design The chosen design was Option 2 as it provided a more compact design solution and by clever use of the sloping site the ward could be terraced which effectively makes the one building look and function as two thus minimising the massing thereby enhancing the domestic feel.

The design also allows for separation of the facilities for adult patients from facilities for older patients while retaining easy access to both buildings for the staff using common areas.

As the design has developed the effect of terracing has been used to produce a building which is split in to two levels while functioning as one. The content of each level is as follows:

Level 1 This is the lowest level facing south-east and is for the acute adult patients. Within this level there are both male and female wards divided by shared space and the Intensive Care Unit. There are secure gardens for the inpatient wards and the ICU. The main reception and the assessment units are used to link this level with the upper terrace, Level 2.

A New District General Hospital for Tunbridge Wells

Design Review

Mental Health Unit Level 2 This terrace level will contain the inpatient ward for older people. This ward is arranged in two distinct areas and shares some facilities including a secure garden. This ward leads to the CMHT administration offices and the Elderly Day Centre which are provided at the same level. The upper storey above the Male and Female Adult Wards is approximately half the size of the level below.

Due to the terracing it has been possible to provide direct street access to both the CMHT administration and the Older People’s Day Hospital (which is constructed as a second floor of the adult building at level 1).

The Older People’s Day Hospital has access to a roof garden.

The plant space for the building is within the roof space of the central core above Level 2.

Access Routes within the Site Within the site, the main access road will provide a route to the main car parks. Car park traffic will turn off the access road shortly after entering the site. Other traffic will continue into the site. Provision is made at the main entrance for a turning area in order to allow public transport services to stop close to the entrance.

The primary and secondary access roads will be connected via a roundabout at the Northeast end of the site which will allow the traffic to flow around both sides of the main hospital and not on the primary fire and vehicle routes.

Decant Strategy The Trust has undertaken a detailed space utilisation survey of the Pembury and Kent & Sussex Hospitals, and this has identified all the requirements of the parties occupying these sites if or when these parties have to be decanted. The solutions have been discussed in detail with stakeholders, detailed plans drawn up and costed by the PFI Team and approved by the Trust Board.

The Trust has produced a detailed decant strategy site to allow construction to take place on the lower half of the site.

The general principle is for non-medical support services to be moved off-site into alternative accommodation. Essential administration that cannot be split from the acute services will remain on the site.

Early reconfiguration work is to be undertaken which will relocate medical wards (dark blue) to Kent & Sussex Hospital and Maidstone Hospital, 12 months before financial close.

The drawing on the right indicates the decant moves from the lower half of the site to the top (ie: red to red, green to green, pale blue to pale blue etc.)

Decant Strategy The drawings opposite illustrate the phasing of works and subsequent decanting. The ‘Construction Phase’ drawing shows the continuing use of the accommodation remaining in the upper position of the site - post demolition of accommodation on the lower part which will be occupied by the new Acute Hospital.

The Mental Health Unit to the eastern edge of the site will be the first of the new buildings to be constructed and occupied. The Acute Hospital will also be under construction at this time.

The existing spine road will still be in use to service the upper site clinical area. Temporary car parking for 120 vehicles is shown at the north-east portion of the site.

The ‘Site at Completion’ drawing illustrates the site subsequent to the decanting of clinical services to the new Acute Hospital. The spine road is relocated parallel to the north of it’s present route. The 3 storey car park is constructed, and the helipad completed in close proximity to the Emergency Services Block on the southern edge of the Acute Hospital. The Car Park is directly linked north-south to the Acute Hospital’s entrance. The environs of the new spine road and car park are extensively landscaped - see page 23 for landscaping proposals.

Design Review

Conclusion

The Trust recognises that good design is fundamental to achieving high quality public buildings. We therefore seek a design that will be functional, of high quality, efficient and sustainable, has good relationship with its surroundings and is aesthetically pleasing.

We believe that a well designed hospital will help patients recover their health and spirit.

A well designed hospital will provide a pleasant working environment for our staff.

A well designed hospital will also bring the communities together and engender civic pride.

It is this vision that the Trust now aspires to achieve.
