Projects We're
Proud Of
Over 15 years of building and maintenance projects across London and Hertfordshire. Every project is delivered to the same standard — the one we'd want for our own homes.

Double-Storey Rear Extension
A full double-storey rear extension on a Victorian terraced house, creating an open-plan kitchen-diner on the ground floor and a new master bedroom with en-suite above. Matching London stock brick throughout.

Single-Storey Kitchen Extension

Master Bedroom Loft Conversion
A full Velux loft conversion on an Edwardian semi, creating a master bedroom with exposed painted beams, built-in wardrobes, and a private en-suite bathroom.

Full Kitchen Refurbishment
A complete kitchen transformation in a Victorian semi — navy handleless units, quartz worktops, large-format porcelain tiles, and a bespoke island with brass pendant lighting.

Commercial Office Fit-Out
A full commercial office fit-out for a growing technology company — open-plan layout, glazed partitions, bespoke timber joinery, polished concrete floors, and a statement reception.

Home Cinema Basement Conversion
A full basement conversion beneath a Victorian terraced house, creating a luxurious home cinema and lounge. Full structural underpinning, Type C cavity drain waterproofing, and bespoke AV installation.

Garage to Home Office Conversion
A full integral garage conversion into a bright home office with a large roof lantern, bespoke built-in desk and shelving, engineered oak flooring, and full insulation to Building Regulations standard.

Full Roof Replacement
A complete roof replacement on a 1930s semi-detached house — new dark grey concrete interlocking tiles, new UPVC fascias and soffits, new lead flashing, and new guttering throughout.

Luxury Bathroom Renovation
A complete luxury bathroom renovation — freestanding oval bath, walk-in rainfall shower, large-format marble-effect porcelain tiles, floating vanity unit, and brushed brass fixtures throughout.

Garden Office Studio
A bespoke garden office studio — timber-clad structure with a mono-pitch roof, large aluminium sliding doors, built-in desk and shelving, full insulation, and mains electricity.

Timber Porch Canopy Build
A bespoke timber porch canopy built over a front door on a 1960s semi-detached house in Borehamwood. Structural joist frame, corbel support brackets, and a tiled pitched roof — all matching the existing property materials.

Loft Conversion — Velux & PIR Insulation
A full loft conversion with Velux roof windows and 100mm PIR insulation boards installed between and over the rafters. The old mineral wool was stripped out entirely before new airtight insulation was fitted to current Building Regulations standard.

Full Roof Retile — New Battens & Clay Tiles
A complete re-roof on a detached house — all old tiles stripped, new treated timber battens fixed to the rafters, and new machine-made clay plain tiles laid in a staggered bond. Broken verge and ridge details repaired throughout.

Flat Roof Extension — OSB Deck & EPDM
A single-storey flat roof extension with structural OSB decking installation shown mid-build. The deck is laid over insulated timber joists before the EPDM rubber membrane is applied — a method that delivers a 30-year life expectancy with zero maintenance.
