Big Yellow, Chiswick

Big Yellow Self Storage wanted a new flagship storage building next to an elevated section of the M4. The client only wanted to use part of their site for the multi-storey construction as the remaining area would be used for future development.

The client requested the building have a sculptured design with curved elevations and glazed cantilevered protrusions. The main tower building has seven storeys above ground level with an overall storage area of 115,000 ft² plus a two-storey extension to the west of the site. The ground floor would act as a service yard with turning space for HGVs.

The site was surrounded by existing buildings and Network Rail tracks, as well as the A4 and elevated M4.

After negotiating approvals with both Network Rail and Transport for London, and providing advice on geotechnical and contaminated land remediation, CampbellReith created a structure with a large column-free yard by suspending the upper six floors from large steel trusses in the roof.

Piled foundations, vibro stone compacted ground and ground level storage slabs were used to support the steel framed superstructure.

CampbellReith also designed a new access bridge link and roadway linking the A4 to the lower levels of the site.

CampbellReith provides consultancy services as part of a framework agreement with Big Yellow Property Company for their portfolio of sites. The initial services are pre-planning and due diligence land quality services which inform purchase negotiations and also ensure negotiations with the regulatory authorities are undertaken at an early stage.

We provide bespoke versions of reports and specifications which are required by Big Yellow and have also designed detailed remediation strategies to enable development of their more contaminated sites.

A wide range of potentially problematic sites have been considered under our remit for Big Yellow including a wide range of historical uses.  This includes former solvent and printing works, manufacturing sites and commercial / residential sites.  On a number of these sites, specific forms of remediation have been completed including in-situ bioremediation of groundwater and ex-situ soil remediation.
