LOCATION

The site is located at 119 Farringdon Road, Clerkenwell within the administrative boundary of the London Borough of Islington. It consists of a plot of 0.24 Ha.

BRIEF & STRATEGY

Demolition and redevelopment of the existing office building (Class B1) to provide an 8 storey (plus lower ground floor) building with office use (Class B1) at part lower ground, part ground and upper floors and flexible commercial uses (Class A1,A3,D1) at part lower ground and part ground floor level along with associated landscaping and a new area of public realm.

According to the Design & Access Statement for the site the scheme seeks to:

• Provide high quality contemporary architecture and landscape design with a holistic redevelopment of the site.

• Replace the existing building which has limited architectural merit and below standard office accommodation compared to the developing market

• Provide significant improvements in quality and quantity to the public realm around the building.

• Be sensitive to Farringdon Road townscape and the surrounding historic context, including neighbouring listed buildings, and to the wider Clerkenwell Green Conservation Area.

• Respect the amenity of the building’s neighbours.

• Provide opportunities for a wide range of office, retail and other commercial tenancies.

• Provide an BREEAM ‘Excellent’, with an aspiration of ‘Outstanding, rated scheme, including a 35% improvement in CO2 emissions over Part L2A 2013 building regulations, and an 69% improvement over the current CO2 emissions produced by the existing building.

• A significant positive enhancement to the ecology and biodiversity of the site as part of a holistic approach to the landscaping, creating new habitats to support local wildlife.

ORIGINS OF THE PROJECT

Previous building was originally built in the 1970s as a warehouse and until 2007 was the home of the Guardian newspaper. It was set back from the historical building line to Farringdon Road. It was regarded as of no use in its existing form due to inefficiency in planning, structure, servicing and general wear-out. Also, this obscure structure didn’t match the site as it didn’t suit the atmosphere of the neighbourhood and was too tall.

The project has been subject to many planning applications. In 2007 an application was granted for a 7-storey residential scheme. It also included the removal of all the trees on Farringdon Road. In 2008 two planning applications were submitted to Islington Council to demolish the existing building and construct a new office building. All the applications were subsequently withdrawn. The scheme was not only considered to be unsuitable in terms of massing and design for the Clerkenwell area, but it also suffered from daylight and sunlight issues, to the residential properties on Crawford Passage, and did not provide adequate pedestrian links or public realm.

The site has been acquired by Viridis in 2012, for the demolition and redevelopment of the existing building. The proposed scheme envisioned an 8-storey structure with office (B1) and commercial (A1, A3 and D1) uses along with associasted landscaping of the public area.

ADMINISTRATION

ARCHITECT’S APPOINTMENT

AHMM was selected as the lead designer on the project through an invited design competition in 2012. It performs all the scope of architectural services including preparing the design, taking part in negotations with local authorities, coordination of the project and inspecting the works whilst on site.

Nevertheless, it is not authorised to make any changes to the design unless instructed to do so.

Current project delivery system is Design&Build, which means that the contractor is administering the architect’s appointment.

The architect’s office assigned 5 consultants to work on the project- Laura, Philip, Marc, Sean and Agata.

SITE MEETINGS

There are different types of site meetings, depending on the subject matter. Usually the benchmark consists of client meeting with architects, contractor and different subcontractors (It is worth mentioning that loads of various subcontractors are brought in or dismissed through the construction process).

COMMUNICATION

To solve the problems on-site the contractor is using a software called SnagR. If there is any issue, the inspector just has to take a picture, describe it and point it on the drawing in the app and everyone using the program has the instant information.

CONTRACT & CONTRACT PERIOD

Administering the contract is one of the subcontractors- Gardiner & Theobald.

At the moment project is on its course to be completed within the contract period. The contractor has predicted spare time for any possible errors and the construction is going as planned. In the unlikely event of project over running the deadline, there are financial penalties counted in costs per week. Yet, if the reason for delay is properly demonstrated, those penalties can be negotiated.

PROJECT QUALITIES

According to the architects the project is driven by all- budget, programme and quality- at the same time. None of those should be favourised or left out, as the building would suffer from it.

STATUATORY APPROVALS

PLANNING PERMISSION

The applicant achieved planning permission in 2015 after two-years long pre-application meetings and consultations. Amongst consultees were: London Borough of Islington (Design Review Panel, Highways, Tree Officers, Sustainability, Street Environment, Members Forum), Greater London Authority, London Underground Limited, Royal Mail, Thames Water, UK Power Networks, London Fire and Emergency Planning Authority, Public Consultation, Metropolitan Police Service and Crime Prevention Design Advisor.

Town & Country Planning Act 1990 (as amended) Greater London Authority Acts 1999 and 2007 Town & Country Planning (Mayor of London) Order 2008

Planning application no. P2015/4143/FUL Planning report no. D&P/2220b/xx

PLANNING CONDITIONS

The site is subject to the Clerkenwell Green Conservation Area (CA01), London View Management Framework Strategic Viewing Corridor of St Paul’s Cathedral from Kenwood House and Parliament Hill, Central Activities Zone (CAZ), Employment Priority Area (General), Farringdon / Smithfield Intensification and Area Site Allocation BC43.

The main issues involved height of the proposal (regarding the protected view management), trees from the Farringdon Road elevation side, sunlight access, heritage listed surroundings and affordable work space allocation from the council.

BUILDING REGULATIONS

The project ended up involving consultees for solving the building regulations, as Access Officer, Design and Conservation Officer, the Energy Conservation Officer, the Tree Preservation Officer, Public Protection Division, Transport Officer and Sustainabillity Officer.

14

INCLUSIVE DESIGN

The project has included the inclusive design in numbers of ways. The access consultant has been involved in the preparations.

Thanks to the site levelling, the building is easily accessible from both Farringdon Road and Crawford Passage. It’s proposed for two on-street wheelchair accessible parking spaces to be provided, potential locations have been identified.

All entrances will provide level thresholds, solid entrance matting and will be clearly articulated within the elevation. Those will be equiped with automated swing doors or drum doors. All fire exits have level thresholds and openings in line. Glazed doors and screens will have manifestation in line.

4 passenger lifts will be serving all the floors with an additional goods lift and a fire/evacuation lift.

Stairs are designed with the guidelines for use by people with ambulant and visual disabilities. Floor finishes in reception areas will provide good visual contrasts and generally aim to provide a slip resistance.

An accessible shower/WC has been provided in the Lower Ground changing area. An accessible WC has been provided on all floors of the office accommodation and reception area. The location is centralised on the floor plan and this allows a travel distance in most instances of 40 metres or less. The door will open outwards in case of emergency.

There are still subjects of design that haven’t been sorted out which cover: decoration, lighting, fire alarm details, lift details, signage, furniture selection and kitchen layouts.

FINAL CONCEPT

16

MODERN METHODS OF CONSTRUCTION

The main method of modern construction is possibly the prefabrication of materials. The products we have had the opportunity to come by were the stairs, precasted twin walls and the faรงade. Both twin walls and stairs were imported from Ireland. The walls were precasted by Alumed. As for the faรงade slabs, those were prefabricated by Decomo in Belgium. All are transported to and assembled on site.

SITE VISITS

27th October 2017

Dear Sir,

We are second year Architecture students at the University of Westminster. This year we have a module focused on the Site Diary. The aim of this module is for students to gain an insight into the role of an architect when a building project is on site. We have noticed your project on site at 119 Farrington Road and we believe this would make an ideal Site Diary study project for us.

We decided to email you and ask for an access to your site and allow us to visit it, ideally with the project architect and ask him/her a few questions about the project. We are fully insured through the University of Westminster for site visits and would be professional in our behaviour and respectful of any time your office would give us. We have attached a confirmation letter from the Head of Department of Architecture. If you have any questions please do let us know.

Of course we would understand if you are too busy, and perhaps in this case you would be kind enough to pass on the contractor’s or project manager’s details for the site and we will contact them.

This is a great opportunity for us to learn about the profession we have chosen. We would be very grateful if you could come back to us regarding this.

Thank you for your time and we look forward to hear from you soon.

13/11/17

Appointment- Monday, 13/11 @14.00h

Entering the site we’ve had to sign in the visitors book, specifying the purpose of the visit and our host. Straightaway we were directed to the temporary offices erected on the upper-ground level. That’s where we met with our contact- Gavin. He gave us a short introduction about the project and asked about our site diary assignment. Shortly after architects arrived- Phil Richards and Laura Carrer. They’re the main coordinators of the project from the AHMM side.

First, we talked about our assignment and expectations of the meetings, then they gave us a thorough presentation including all the planning, concepts, drawings of the building as well as information on the client and the contractors and architect’s appointment. Afterwards, each of us got a PPE set (safety helmet, googles, gloves, high-visibility vest and toe-capped shoes) and went around for a site tour.

To enter the construction site, there is a special gate with reminders about PPE and H&S regulations.

For our tour joined us Jason, the site manager. We went around floor by floor, with the architects explaining us the details of the construction. During the walk we learned the true nature of architect’s role on site. It was not only checking if the construction goes according to the design, but also controlling the quality of delivered building for the time being and consultant for the alterations in the project.

They showed us how the services were installed on the lower levels, the erection of floor slabs andpartition walls, the prefabricated materials and how those are put together or transported to the higher floors. We’ve had the opportunity to see how construction of the floor looks like as well as the finished piece.

In the end we were taken the lower ground level to see the storage and the mechanical room with all the boilers, heaters and electrical machinery.

Leaving the site, we’ve returned the PPE set, arranged initial date for our next visit and signed out the visitors list.

Appointment- Monday, 22/01 @10.00h

This time we’ve had only construction site visit without the Q&A session. Our guide was Oliver (?), fresh construction graduate, who just started his job at McLaren. We went straight for the top floor, which was being prepared for the construction of the final storey. To enter it we’ve had to use the secured ladder instead of the usual stairs.

The concrete was matured so it was ok to walk on it, yet the bearing walls were still under construction. We’ve had the opportunity to see the wall structure in detail and the process of pouring concrete into the construction. Our guide also explained us how the crane is going to be removed after the construction finishes- it will be dismantled into parts, taken away and the prepared floor holes are going to be filled with reinforced concrete. Also, the top floor was being checked by building surveyors if the concrete was evenly distributed.

At the time of our visit, different steps of construction could be seen throughout building storeys. On lower levels, erection of the partition walls and services has already started. We could see first attempts for installing bathrooms or elevator wiring. It was also the first time we could see all the steps of assemblying the façade- from transportation, conservation and lifting, through assembly and filling it with insulation to the finished piece.

In the end we were taken to the basement and mechanical rooms to see the improvement there.

The wiring was being installed and we could see the delivery dock conveyor in use. Leaving the site we’ve seen the suggestion board as well as instructions on good and bad practice. In my opinion it’s a nice way of communication between the board and the workers.

Appointment- Wednesday, 07/02 @14.00h

Our final site visit was appointed with the architects, so we could get the missing answers for our technical studies assignment. We took part in the on-site meeting of architects and architects’ assistants.

They’ve had to sort out some issues regarding detailing of the site.

We went through the lobby to the basement, where was the issue with placing the fire curtain, as some of the pipes moved a bit and it needed finding a fitting aesthetic solution. Later, on the 1st floor there was a problem with the height of mirrors, which turned out to be higher than it seemed on the plan. Next doors the walls were to thick, yet according to the council rules and regulations there was nothing to be done. Finally, the architects had to check the colour of the used mortar to match it with the upcoming brickwork.

After everything was sorted out, we proceeded onto the top floor, which was actually finished and the roof was being installed above. The floor slab was finished and secured and the steel frame for a curtain wall, installed and ready. On our way downstairs we could see the finished façade, with the detail being assembled altogether with window frames.

Our visit wrapped up in the offices, where we talked with the architects’ assistants and the project director.

CONCLUSIONS

When with Alicja, we’ve received a mail from the site confirming our first visit, we were just astounded. We felt honoured to be able to study the 119 Farringdon Road.

Years ago, when preparing for an interview I was asked a question about incorporating old and new in the architecture. I’ve been looking for an answer since and I can proudly say that I finally found it. The AHMM’s design is a perfect match of modern architecture on a historical site.

Discussing the first visit with Alicja, we both decided that we’re pleased by the design. At first I wasn’t quite convinced by the façade, but seeing it in flesh made me instantly love it.

As we both had experience with the built environment in Poland before, we were amazed by the neatness and tidiness on site. The collaborative work of all the contractor and subcontrasts is worth the applause. Even though there were some minor issues with the chipping out the pillar or mirror height in the bathroom, I’d say the applicant made a good choice for the constructor.

The site diary assignment has been a great opportunity to witness the built environment. We have not only seen the process of construction in flesh, but also experienced the pace of work and relationship between architects, client and (sub-)contractors.

For me, the most important observation was the role of architect during the project and on-site. I’ve imagined it completely different and it kind of enlightened me in the sense of future career. Also, finally being able to see in person the process of construction gave me the idea on how to plan the technical design, what are the possible solutions and how does it work step by step.
