The Boiler House
Cross-laminated timber residential building
Our structural engineers in London worked on a new cross-laminated timber (CLT) residential building known as the Boiler House, located in the Old Vinyl Factory regeneration scheme in west London.

The six storey building is constructed on an in situ reinforced concrete 600mm deep raft foundation and includes a first floor transfer slab. A total of 54 studio, one-bed and two-bed apartments are accommodated, with two commercial/retail units at ground level and a shared roof garden. The CLT structure uses sustainably sourced timber, and is clad in stainless steel shingles. Many of the apartments include balconies.

Our client was first the specialist developer Hub Group, then Henry Construction, which was the main contractor. Concept design was by architect Studio Egret West, and the delivery architect was Stride Treglown. To realise the design intent, a special finish ‘white’ concrete has been incorporated into exposed columns at ground level and the first floor slab soffit above the entrance lobby.

We were able to find substantial cost savings for our client and reduce the programme length by several weeks through our geotechnical expertise and design capabilities. The original foundation specified was a piled solution, which we demonstrated could be effectively replaced with the concrete raft.

The Old Vinyl Factory is a 17 acre scheme near Hayes & Harlington railway station, to be served by Crossrail when this part of the line opens in 2019. The Boiler House occupies the site of the old steam and heating plant that once served the famous EMI record-pressing plant and research laboratories.

Whitby Wood was responsible for structural and civil engineering for the project, and lead engineer on the geotechnical design, which was provided in association with Wood Thilsted.
