Project overview

HMO conversion in West Hampstead

This three-storey townhouse was converted into a 28-bedroom, 23-bathroom HMO. The brief demanded a substantial increase in accommodation while preserving the period features that made the original building distinctive.

01 · The challenge

Underpinning and two additional floors

The programme included excavation, underpinning, significant steelwork and two extra floors. All of this had to be carried out inside an existing building without damaging the period details being kept.

02 · The response

Sequencing structure, services and finishes

JBP brought design and construction decisions together, sequencing the structural work before coordinating new layouts, services and finishes. Buildability reviews helped the design team resolve details against the conditions uncovered on site.

03 · The result

28 bedrooms with period character retained

The tired townhouse now has a new long-term use and keeps its period character. The conversion provides 28 bedrooms and 23 bathrooms, with restored and modernised shared spaces.

Project experience

Experience in complex HMO conversions

At 28 bedrooms, Greencroft Gardens is the largest HMO conversion in our case studies. Adding that many rooms meant the building had to grow: digging down, underpinning, steelwork and two new floors, all built around period features that had to survive the work.
