Primrose Hill >
Primrose Hill House is a contemporary three-storey (plus basement) single-family residence positioned to capture stunning views of the adjacent park. A substantial basement delivers extensive parking alongside outstanding leisure amenities. Ancillary accommodation for guests and staff is provided separately from the main house, over a basement incorporating the car lift. SOLID provided Civil and Structural Engineering from RIBA stages 1-6.

The Challenge
To accelerate the construction program, the basement works were carried out in two phases. The Phase 1 basement structure was required to support significant construction traffic, material storage, and excavation loads. The phase 2 basement was then constructed using a top-down methodology, allowing excavation and basement works to progress concurrently with the erection of the main house superstructure.
The SOLID Approach
To facilitate the top-down construction, SOLID incorporated temporary piles into the structural design, enabling the ground-floor concrete slab to act as a load-bearing platform during the basement excavation below. A detailed finite element analysis (FEA) model was developed to analyse and design both the final condition and multiple intermediate layouts and load conditions encountered during construction.
The FEA model was also used to assess long-term deflection of the concrete structure over the column-free parking area and inform pre-camber requirements.
