Project CH - Case Study
Christchurch Hill
LOCATION
Hampstead, London
PROJECT TYPE
Residential Redevelopment
DURATION
14 months
SIZE
250 sqm over five levels
2700 sq ft
This mid-terraced Victorian home in Hampstead Village underwent a complete redevelopment across five levels. Initially built in the 1870s, the property was transformed into a turnkey contemporary family home, with only the original façade retained.
All internal floors, the roof, rear elevation, and chimney breasts were removed and rebuilt. The project’s complexity centred around the design and execution of a bespoke temporary works system to support the retained façade and adjoining party walls.
Delivered in a conservation area and on a tight urban site, the build required precision, technical skill and close collaboration across all disciplines.

Pre - Works
Point Cloud - Post Strip Out
We used in-house 3D scanning to capture the site from the strip-out stage through to post-works, enabling seamless collaboration and maintaining a detailed visual record of conditions before and after construction.
Challange
Working within a conservation area, based on a hill, the project demanded detailed planning, and a strong method process. after strip out is was evermore clear that the floor structures and the brick walls had severely deteriorated and had lost their structural integrity and required full re-build.
The Approach
PELHAM & Co. delivered the project entirely in-house through a fully integrated design-and-build process. Coordinating all teams under one roof ensured every stage aligned with the design intent, maintaining precision, quality, and efficiency throughout.
Structural Highlights
The project involved the complete reconstruction behind the retained façade; it required the design and installation of a bespoke vertical and horizontal Mabey temporary works system to support the retained façade and adjoining party walls. Every stage required exceptional precision, detailed planning, and seamless collaboration across all disciplines, enabling safe rebuild within a confined urban site.
Structural Highlights
After installing new structural steels floor by floor and removing the chimney stacks internally we rebuilte each floor structures flooor-by-floor, new internal layouts were formed with a temporary staircase installed for the first fix M&E to be installed.
Transformation - External
The exterior rear elevation was completely removed and rebuilt. This allowed us to improve the building's structure, enhance its energy efficiency, expand the basement level, and create a master bathroom where an unused balcony had been located. Keeping the original detailing and carefully selected bricks to give the façade a timeless yet contemporary finish.
Transformation - Internal
The property was comprehensively modernised with new double-glazed windows and a complete installation of electrical, plumbing, and heating systems to meet modern performance standards.
Transformation - Finishing
Traditional plastering and underfloor heating were introduced throughout, while full basement tanking ensured durability, comfort, and long-term protection against moisture.
