Eye-catching regeneration in an urban setting.

A set of futuristic development proposals conceived by architect Will Alsop OBE are attracting attention in Brentford, West London.

Project outline

Located with Hounslow’s Golden Mile, the proposed mixed use regeneration scheme on this former industrial site includes three circular and hive-like high-rise towers, located within a new public park on a podium deck.

The scheme’s design concept was conceived by a team led by architect Will Alsop OBE, founding director of aLL Design which has a reputation for innovative and highly original work. The eye-catching buildings form the centerpiece of the scheme proposals, responding to the strategic gateway nature of the site off Chiswick Roundabout and adjacent to the new Brentford FC stadium. The three towers accommodate up to 400 residential units and flexible commercial space with a bus depot, car parking, services and plant located below the deck level in a double height podium and basement.

Our role

Given the nature, the unique design, and the scale of the scheme (particular due to its height and massing on the skyline) as well as the potential for cumulative effects from a number of other development proposals within the immediate area, we were commissioned to undertake an Environmental Impact Assessment (EIA) and preparing an Environmental Statement (ES) to support the full planning application. We were also commissioned to provide the associated environmental design support.

The scheme’s proximity to the A4, elevated M4 and Heathrow Airport, in particular, required our considerable specialist noise, air quality and microclimate expertise to not only assess likely effects on the scheme on the environment, but to also demonstrate the suitability of the proposed scheme (in environmental performance terms) in this location.

Our value

  • We have considerable experience of the constraints relevant to this type of scheme and have been able to ensure the robust scoping of the EIA and preparing of the ES.
  • We are working closely with the architects to ensure that the residential units and open space satisfy environmental standards while maximizing commercial value.
  • We have brokered consensus with the local authority on the likely effects of the scheme through appropriate (and at times complex) physical and numerically acoustics, air quality, wind environment and sunlight, daylight and overshadowing modelling.
  • We have proactively worked with team members and stakeholders to respond to concerns in relation to potential effects of the scheme on the adjacent operational railway land during construction, as well as in relation to potential visual effects on the Kew Gardens UNESCO World Heritage Site.
