Camberwell Lanes Development


Camberwell Lanes Development

Proposed 25,000m2 mixed use development in Camberwell, Southwark set over 3 phases: Block A – building a hotel/ residential over the existing shopping centre; Block B – new build residential and Cinema over existing supermarket; Block C – 12 storey RC new build residential tower.


Block A – A 12 storey RC residential tower combined with a lightweight 3 storey residential set over a new basement. The structure to the tower comprises of an RC frame on CFA piles and is  stabilised by RC shear cores. Due to planning restrictions on height the slab depths have been slimmed down to 220mm in conventional RC, although PT slabs were also explored. Precast columns and walls are being considered to speed up the construction process. The basement is formed with a secant pile wall due to the high water table and the low rise apartments will either be formed from tradition methods or MMC.


Block B – Phase 2 of the project involved creating 100 new residential units adjacent to the Morrison retail unit with new Cinema complex located above the store. We were asked to explore the feasibility for the retail unit to remain in operation through the construction works. The capacity of the existing structure was found to be inadequate to support the new loads from the Cinema above, therefore the existing internal foundations and columns are to be upgraded. This can be carried out in a careful sequence and night working to cause minimal disruption to the retail unit. SD have developed an outline construction methodology and construction sequence video to demonstrate this to the stakeholders.


Block C – The proposed development at block C comprises  of mix residential, commercial and retail spaces. The structure is to be extended by 5 storeys on top of the existing building with a new hotel to the north part of the development and residential apartments to the south of the building. The key constraint for the development was to minimise disruption to the ground floor retail units which are to be retained. A detailed appraisal was carried out to explore options for the oversite development including storey deep Vierendeel girders to span over the existing units to strengthening and building on top of the existing structure. By undertaking specialist geotechnical and fabric surveys we have been able to justify the capacity of the existing structure without expensive and intrusive strengthening works or the need or heavy transfer.


Each block is modelled in 3D. Due to the complexities around the existing buildings, the design model is phased to show each key step in the construction sequence and can be viewed with our augmented reality software.
