Six recent projects in London and Hertfordshire, from a 28-bedroom HMO in West Hampstead to a listed barn conversion in St Albans, with contract values from £150k to £1.3m.
Every project brought its own mix of structure, approvals, programme and budget pressures. Each case study sets out the brief, the main challenges and how we delivered it, working with the client, architects, consultants and trades.
Design-and-build conversion of a listed barn into seven holiday-letting apartments, balancing retained character with extensive structural work.
Structural repairs, deep foundations and a floating reinforced-concrete slab were coordinated alongside green-belt and archaeological constraints. Original A-frames, flint and brick flooring were retained, with new curtain walling bringing light into the completed scheme.
A design-and-build conversion creating a 28-bedroom, 23-bathroom HMO while preserving and restoring the building’s period character.
The programme included underpinning, lowering the existing structure, substantial steelwork and two additional floors. Careful sequencing allowed major interventions to proceed while protecting key heritage features.
A four-bedroom timber-frame home delivered as a turnkey project, integrating an air-source heat pump and other renewable technologies.
JBP coordinated the technical information and buildability decisions needed to maintain momentum despite limited design information at the outset, delivering the complete home within a concentrated programme.
Conversion and extension of a residential property into an 18-bedroom, 12-bathroom HMO with a high level of technical coordination.
New drainage, utilities and structure were built into the retained building across changing levels, with detailing that respects the original house.
A 10-bedroom, five-bathroom HMO refurbishment that required responsive structural problem-solving and design coordination.
Structural defects found during the work led to design changes. JBP coordinated the response, and the reworked layout gained an extra bedroom and three more bathrooms.
A rundown semi-detached house in Tottenham turned into a four-bedroom HMO on a 16-week programme.
Hidden structural problems were found during the work. We assessed them quickly, adjusted the plan and finished the property within the agreed programme.
Good results depend on the work behind the scenes: checking the information, planning the order of work, managing risk and keeping everyone informed.
