Merthyr Tydfil
Sub heading Body text Sub, sub titles
Proposed site St. Luke’s Church Current Gellideg Foundation accommodation in flats
Site of old steelworks Merthyr Tydfil
Site Location Merthyr Tydfil is situated approximately 23 miles North of Cardiff in South Wales. Gellideg is a social housing estate which lies to the North East of Merthyr town centre. The estate has suffered with the decline of manufacturing in the area and currently experiences high levels of unemployment and social exclusion.
Row of shops
Disused car park
The site is situated in the heart of the estate, on a slope which overlooks the Brecon Beacons to the North and East. The site was originally occupied by a community centre, the Gellideg Working Mans Club, which burnt down some years ago. The site is adjacent to a row of shops along Hoel Tai Mawr (which is a bus route). It is also bounded by Lansbury Road to the East, a ball court and a community church to the South and a disused car park to the West. The site has a slope from West to East of approximately three metres, and is currently grassed over the fill above the foundations of the former building. The aspect is relatively open on all sides apart from the West. There is some parking in a lay-by on Lansbury Road and the potential for more on the disused car park to the West.

Site Analysis Advantages and constraints of the site: The site is located at the heart of the Gellideg Estate and has a strong presence in an elevated position on the main approach road into the estate. It is adjacent to a bus stop and a row of shops along Heol Tai Mawr, and looks out towards the Brecon Beacons to the North and East.
Active Frontages Existing Pedestrian Routes Potential Vehicle Access
There is opportunity to provide vehicle access along Lansbury Road to the East or along Heol Bryn-Y-Gwyddyl, an access road to the back of the neighbouring shops to the West. The main functional constraint to the site is the topography which makes achieving level access difficult, but contributes greatly to the character and richness of the site, providing fantastic views to the North and East. The area immediately surrounding the site has been neglected and is mainly used as a meeting place for local youths and as a cut through across the estate. The area around the back of the shops to the West is neglected and unsightly. Access will need to be maintained for delivery vehicles to the back of the shops so this will need to be screened from view. There is the opportunity to look at master planning the wider area surrounding the site. By addressing the disused car park and play area to the West and the MUGA and St. Luke’s Church to the South, there is the opportunity to revitalise and link the facilities provided in this area.

Site Analysis: Site Section
Site Sections The site section demonstrates a considerable difference in levels from East to West. The levels currently show a 3.7m fall from the higher West side of the site to the lower East side. The only buildings in close proximity to the site are the row of shops outlined to the top of the section in the West. Despite being only single storey units, their location towards the top of the slope means they will overshadow the North West corner of the site in the evening. At the lower end of the site, across Lansbury Road, are the four storey flats currently occupied by the Gellideg Foundation. Despite being much taller buildings, their location further down the slope, and their distance across the
road, means they don’t overshadow or enclose the site. The level change through the length of the site poses a challenge to maintaining a level access to and within the building without extensive groundworks, ramps or lifts. The orientation of the site, with its relative openness to the South, means there is potential to maximises the benefits from solar gains to south-facing glazed elevations throughout the year.

Design Development Consultation The brief was developed and informed through consultation with the Gellideg Foundation staff and volunteers. Consultation engagement was conducted in a series of meetings and observations with the staff and volunteers at the centre and more focused strategic reviews with the management staff and trustees. Aspirations for the new building, and facilities required to best promote the Gellideg Foundation were explored and discussed. Feedback and comments were recorded, interpreted and fed back into the brief development. Key Themes and Objectives Much consideration and discussion was given to the question of security. The building needs to be highly secure and impenetrable out of hours, at the same time as being a friendly and welcoming community building at the heart of the estate. The building must also be low energy and take maximum advantage of passive solar gains for heating and good natural day lighting to reduce reliance on artificial lighting. Therefore a high glazing ratio is desirable. This contradiction between the practical need for very good security and the desire for ‘openness’ and transparency at the social level, as well as the desirability of having a building full of natural daylight, has informed the layout of our design proposals. Design Concept A solution to the contradictions highlighted above is to have a ‘perimeter scheme’. The building would follow the outline of the site allowing the centre of the site to be freed up as a protected courtyard. Therefore the perimeter can have few, highly controlled and ‘defendable’ openings while the interior courtyard elevations can have all the glazing and a softer, more open aspect.
The disadvantages of a courtyard scheme would be that the exterior could appear too defensive and unwelcoming. The building form is also not very compact, with a high proportion of external surface area which can lead to higher heat losses and the higher costs associated with building external walls. The advantages however, are great. The interior courtyard can have many functions facing on to it and it becomes the primary circulation route around the building. Courtyards tend to feel like friendly places, they are both sheltered and welcoming and offer valuable social meeting places. Providing that the preimeter building is not too high and that the courtyard is wide enough, there should be good solar and daylight access throughout the day allowing a potentially large building to maximise the benefits of passive solar design.
• Those functions that need the most sunlight are located in the South and North wings both of which have potentially large areas of South facing glazing. • The private offices are located on the first floor of the building, along with the private care takers flat. The first floor rooms are arranged around the North and West sides of the perimeter to minimise solar shading of the courtyard. This also means they benefit from a good solar aspect and have far reaching views out across the hills to the North. • The site will be excavated flat at the lower Lansbury Road level. This means a retaining wall will have to be constructed on the West side and for some of the North side. The commercial kitchen, packing room and teaching kitchen will all have level access onto a parking /loading area off Lansbury Road.
Brief Development • Consultation • Key Themes and Objectives • Design Concept • Layout
Layout The basic layout principles are as follows: • The main entrance is located to the North along the main road - this provides level access into the courtyard and the ground floor of the building. • There is a secondary access from Lansbury Road in the East. This access brings people up a wide and shallow staircase from the lower ground floor level, up into the courtyard above. • There is also a third potential access point from the South playground and garden area. This entrance point also provides level access for buggies from the car park to the West. • All these access points will be controlled and can be shut down and secured after hours. • Most accommodation is on the ground floor, surrounding the courtyard and accessible via either an internal or an external covered walk way (or cloister). 18

Sections show: • The layout of the building takes advantage of the sloping site by separating the public and private functions between the different levels. • The South wing of the building is single storey and will allow as much sunlight into the central courtyard as possible. • Large areas of South facing glazing on the North wing will maximise passive solar gains in the building as well as natural day-lighting. • The covered preschool play area will benefit from South light, its direct link with the central courtyard and its elevated position above the street below.

Materials and Energy
29
Materials and Energy Materials • The building needs to be robust, durable and strong. • Have a low maintenance and be easily repairable. • Some elements need to be buildable by trainees. Materials will need to be of a human scale and involve some craft skills and learning potential. • Be made of benign materials - low embodied energy, non-polluting, preferably of sustainably produced renewable (eg FSC home-grown timber) or from common mineral sources, preferably locally sourced. • Highly insulating, airtight constructions, but ‘breathable’ for safety and health reasons. • Of reasonable cost and availability. Construction To satisfy the above, the proposal is to use construction methods that have been used successfully in the WISE building at CAT. • A timber structural frame - studwork where possible (simple, cost effective and easy to construct), with ‘glulam’ beams and columns where needed for large spans. • Walls of cast in-situ Hemcrete - an insulating mix of UK grown hemp shiv and hydraulic lime, mixed on site - approximately 400mm thick. An easy, repetitive task for trainees. Externally, these walls could be clad in pale Roman brickwork for a robust, durable and attractive finish. • Timber I-beam roofs with Warmcell insulation 450mm deep (made in Ebbw Vale). Roof finish in steel trays (preferably zinc coated stainless steel). • Solid ground floors with underfloor heating and perlite insulation 200mm - finishes: timber linoleum, rubber etc (not carpets).
capitol on rising fuel costs. For this reason we are proposing to build to the highest insulation and airtightness standards that we can achieve in this building. Considering the building has such a large perimeter area, it is unlikely we will achieve the stringent energy requirements of the Passivhaus standard (15 kWh/(m2.a) but we can aim to get very close to this. Consideration will need to be given as to whether mechanical ventilation heat recovery (MVHR) is a sensible approach for this building. Renewable energy will mostly be in the form of passive solar heating and lighting, but an ‘auxiliary’ renewable energy heating system should also be considered. A wood pellet boiler would be one option that is both convenient and reliable and will also qualify for Renewable Heat Incentive (RHI) payments. A small solar water heating array may also be considered (also RHI). A photovoltiac array, although a sensible option in energy terms, will probably not be considered for security reasons.
Construction Techniques • Glulam frame with load bearing timber stud walls.
Energy It is eminently sensible that an organisation like the Gellideg Foundation realise a very low energy building rather than go on for years spending 30
