Planning History

The development is set on the edge of the Hall Estate and the Church Street Masterplan so there had been a lot of consultation with residents over the years as well as a previous expired planning permission. DMA carefully worked through previous consultations and with residents to make sure that we understood what was going on without going over old ground. We led 2 pre-application meetings with WCC planning, 1 Resident Steering Group meeting and 1 public exhibition over a 6-month period. The scheme was submitted for planning approval in July 2017 and was given unanimous approval in November 2017.

The Design Process

Part of the broader Church Street masterplan, this development provides 60 new homes for Westminster City Council, of which 19 units are affordable tenure and 41 for private sale.
The site surrounds the existing 22-storey residential Parsons House and had been a bit of an eyesore, in large part covered by a podium deck covering a semi-underground car park.
A new, five-storey, U-shaped building wraps around a courtyard garden and, in doing so, restores the street facades around the site and re-establishes the urban block, using varying heights, materials and details to help ‘knit' together the rapidly evolving streetscape. There is a mix of differently sized flats and maisonettes, with 25 homes single aspect and 35 dual or triple aspect.
The scheme has been designed and adapted around keeping the mature trees on the site, and landscaped to tie in with what was already there, including improvements to the area around the existing residential tower. The larger, affordable duplexes have their own front doors onto Edgware Road where changes in level and landscaping are used to define the threshold between public and private, helping to activate the street and to prioritise family needs. A communal garden replaces the car-park podium, and the courtyard garden provides green space for all residents to sit out and kids to play safely across the tenures, with passive surveillance provided by balconies and strategically placed windows.
As well as improvements to the existing tower, including a new entrance and community room, kitchenette, WC and refreshed communal areas, the project also created added social value for residents with work experience placements to students from local schools and youth groups. DMA also provided 200 hours of pro bono service, helping to improve community facilities including space for youth groups and affordable office space on Church Street.

Sustainability

The design takes a fabric first approach to delivering high levels of thermal efficiency, achieving U-values for walls (63% improvement), Floor (40% improvement), roof (45% improvement), glazing (30% improvement) against Building Regulations Part L 2013 limiting values. This efficiency reduces the overall heating and cooling demand and in doing so, significantly reduces associated CO2 emissions. The mechanical ventilation systems within the building incorporate high efficiency heat exchangers which will incorporate the facility for summer-bypass. This systems also provides roughly 1.5kW cooling which will lower the supply temperature to provide a comfortable, healthy and energy efficient indoor climate. High efficient community gas boiler heating systems were installed to ensure that the heating demands were met while minimizing carbon emissions. In addition, fittings which have low water consumptions were installed to reduce the overall heating and hot water demand, further reducing emissions. The system has also been future proofed to enable connection into the District Heating System. A roof mounted PV array of 32kWp was installed to significantly reduce the mains electrical consumption. The completed development achieves a 20% reduction in regulated CO2 emissions compared to the regulated CO2 emissions baseline based on SAP 2012 carbon factors. Dynamic thermal comfort modelling was carried out to confirm that the completed building achieves the CIBSE TM52 industry benchmark for thermal comfort within the occupied spaces. All units achieved an EPC rating of B except one unit and a block compliance reduction in BER of 18.7% when compared to a Part L compliant building. The energy performance asset rating is better than the benchmarks for a newly built building. There are also biodiverse green roofs and a living wall, in addition to the planting in and around the courtyard and surrounding streets.
