Case Studies

Which? Building, London

Arc Major Projects were happy to manage this complex rooftop extension to Which? Magazine’s new London offices near Regent’s Park. This was a design-and-build project requiring us to fully develop the client’s indicative design. The structure utilises a VM Zinc+ system which carries a 30-year manufacturer’s guarantee.
We also waterproofed and paved the gangways and terrace which will provide a relaxing outdoor space for staff.

Marlborough School

This is a complex, new-build school in the Royal Borough of Kensington and Chelsea; Arc Major Projects managed the contract on behalf of Arc Waterproofing.
There are two main buildings; one is the commercial building and the other is the main teaching block.
The commercial building has a paving and pebble finish whilst the teaching block roofs includes a games pitch with artificial grass and EPDM safety surface over two levels.
We also laid an artificial grass floor covering over a rubber crumb in a room set aside for pupils with special needs.

Belhus Pool

Belhus Swimming Pool is part of a large leisure centre in South Ockendon.
Arc Major Projects were awarded the contract to renew the roof and M&E installations, including the filtration plant, to the pool. The roof is a Langley TA20 warm roof with torch-on felt; the system is effectively super-insulated and will help reduce future energy costs. The roof works were carried out by sister company, Arc Waterproofing.
The new filtration plant replaces the original system, including new boilers.
Arc were also awarded a subsequent contract to reconfigure and fit out the pool changing rooms as well as cleaning and painting the exterior of the waterslide.

London Wall Place

No2 London Wall Place is a new-build 190,000ft2 16-storey tower. Floors 12-16 were pre-let to an international law firm and Arc were engaged to undertake mechanical works to the 15th and 16th floors.
Our remit covered the installation of hot and cold pipework, sanitaryware and fittings, waste services and gas pipework for the kitchens, WC facilities and breakout areas.

Summit House

Arc Major Projects were engaged to improve the roof design on an existing commercial building; the original construction had led to water ingress and so the works were urgently required to prevent further damage to the premises.
The works included reducing the depth of pebbles on the roof, waterproofing over the expansion joints, reducing the area of insulation to the internal walls of the building and providing extended drainage covers to the outlet positions.
The original design had insufficient falls, which we countered by directing rainwater to the outlets by means of incorporating drainage channels.

Chelsea Barracks

Chelsea Barracks is a prestigious new apartment block with many properties already sold off-plan.
Arc were employed to undertake the mechanical installation and bathroom suites.
As a new-build project, many trades were on site simultaneously requiring careful programming of the works and co-operation with others to ensure the project was delivered without delay.
Additionally, with many apartments requiring a different mechanical configuration, excellent site organisation was required.

Whitehall Road

Arc Major Projects were engaged, on a design and build basis, to extend and modernise this four-bedroom detached house whilst retaining period features.
We built a full-width extension, single and two-storey, with bifold doors to connect the home to the garden.
The house also benefited from zonal underfloor heating, a new high-end kitchen, new windows and doors, new bathrooms and wet-room and all finishes. Externally, we built a swimming pool and installed a hot tub, and carried out hard and soft landscaping. All works were carried out by our own directly-employed workforce.

Bentinck Street

Originally a domestic residence, this converted apartment block in Westminster dates back to the 19th Century and is in a conservation area.
Arc Major Projects were engaged to refurbish the communal parts, renew the landlord’s electrics and lighting and install an automatic smoke control system. Externally, the building required brick and masonry repairs and a new lead roof.
Arc Major Projects were able to negotiate a contract to totally refurbish one of the flats, thanks to the quality of our works and the efforts we applied to ensuring residents were not unduly inconvenienced by the works.

Mount Vernon

Arc Major Projects have completed their latest project – two roof gardens at Mount Vernon, Hampstead.

Theatre Works

The Delfont Mackintosh Theatres estate comprises nine world- famous West End theatres, with a tenth under development, and is renowned for staging some of the most iconic productions in theatreland.
London has a rich theatrical heritage and Arc Major Projects are a key player in theatre maintenance, which requires a flexible approach and often a rapid response.
