Webb Yates Engineers provided civil and structural engineering services for the refurbishment and conversion of multiple buildings contained at Erskine Road, Primrose Hill. The project involves new build, refurbishment and demolition works to create high-end office space and luxury residential accommodation.
The envelopes of the existing buildings were left largely unchanged with the major works restricted to providing new circulation spaces internally. The existing buildings were extended upwards to provide additional floor area. An additional floor was added to each of the buildings and contemporary glass boxes were inserted between the existing buildings providing new circulation cores, kitchens and bathrooms and linking the existing buildings. This allowed the new office space inside the existing buildings to be flexible and open planned.
The former piano factory known as Leeder House was converted from commercial space to residential units retaining its impressive façade and restoring it to its former glory. Larger and more efficient floor plans were created by removing existing internal columns. Additionally, the ground floor was lowered to create a double height storey space with a partial mezzanine level and the roof was extended.
Building 5 was demolished and replaced with a new two storey office building. Webb Yates Engineers was responsible for the design of the new reinforced concrete basement raft foundation, retaining walls and ground floor slab and the design of the new steel superstructure framing.
Low carbon strategies including green roofs, photovoltaics and solar thermal panels were incorporated into the scheme and the offices were designed to a ‘BREEAM Excellent’ rating.
