Structural Drawing & Detailing
James Lockyer Associates carried out a structural appraisal to determine the extent and pattern of movement and provided structural design details for a piled raft slab to underpin the full footprint of the house, followed by crack repairs. The porches and conservatory to the house were taken down and rebuilt, along with the garage, on piled slabs.
The owners moved into temporary accommodation to allow the works to proceed. The ground floor slab was completely broken out with internal walls removed and temporary props installed. A mini piling rig was manoeuvred into the house to install the piles. The new reinforced concrete slab extended into pockets formed in the loadbearing walls to support them. Fixtures and finishes were reinstated with the close involvement of the owners.
