HMO conversions
Houses converted, extended and refurbished as HMOs, including a 28-bedroom conversion in West Hampstead and an 18-bedroom conversion in Tooting.
We deliver HMO conversions, turnkey builds and complex residential projects, and we keep clients informed at every stage.
JBP Developments is a construction and project management company based in St Albans, Hertfordshire. Since 2015 we have built, converted and renovated homes across Hertfordshire, Bedfordshire and North London.
Our work covers HMO conversions and refurbishments, turnkey new builds, design and build projects, and the renovation of period and listed buildings. Recent projects include a 28-bedroom HMO conversion in West Hampstead, the conversion of curtilage-listed barns into seven holiday-let apartments near St Albans, and a timber-frame new build in Chorleywood.
Our directors are construction managers, so the people making decisions understand the design, the cost and the build. We talk to clients directly, raise problems early and take responsibility for moving the project forward.

Our work is residential, and most of it involves an existing building that has to change a lot.
Houses converted, extended and refurbished as HMOs, including a 28-bedroom conversion in West Hampstead and an 18-bedroom conversion in Tooting.
Homes delivered from brief to handover by one team, like our four-bedroom timber-frame house in Chorleywood, built in 24 weeks.
Conversions that keep the original character, like Beaumont Mews in St Albans, where we kept the A-frames, flint walls and brick floors.

From our base in St Albans we take on projects across Hertfordshire, Bedfordshire and North London, from HMO conversions in West Hampstead, Maida Vale and Tottenham to a turnkey new build in Chorleywood and listed barn conversions near St Albans. You can see them all in our case studies.
JBP runs every project through Siite, our construction management platform. Site reports, actions, decisions, photos and costs are kept in one place, so nothing gets lost in email threads or spreadsheets.

The businesses are separate, but they share an understanding of complex residential property.
