Complete Home Renovation & Garage-to-Annex Conversion (London)

Renovated exterior with new bay window and garden patio in London home

Project Overview

This project transformed an underused garage and dated interior into a modern, fully refurbished home — with a new annex bedroom + ensuite, updated living spaces, upgraded plumbing and electrics, and refreshed interior and exterior finishes.

Scope Included

Conversion of a double garage into a habitable annex (bedroom + ensuite)
Structural works: wall openings, insulation upgrades, roof adjusting, window/skylight installation
Full interior renovation: reconfiguration of living spaces, updated layout, repainting, new finishes
Plumbing & heating upgrades: new bathroom plumbing, sanitary-ware installation, drainage and water supply modifications
Electrical upgrades & lighting: LED lighting, safe rewiring, updated fixtures and switches
Exterior and finishing works: external cleaning/facade improvement, decking or patio sealing and garden access improvements

Result: The property gained significant functional and aesthetic value — a fully liveable annex, modernised living areas, updated utilities, and renewed exterior.

Why This Project Mattered

Maximised Use of Existing Space — The garage was underused; converting it added valuable internal living space while avoiding costly extensions.
Comprehensive Upgrade — Rather than piecemeal repairs, the project delivered a unified renovation: structure, utilities, interiors and exterior.
One-Stop Solution — From structural work to plumbing, electrical, finishing and external areas — handled by one trusted team, ensuring quality and consistency throughout.

Project Details & Challenges

Structural Adjustments & Compliance — Converting a garage into a living space required careful structural reinforcement, insulation upgrade, and compliance with building regulations.

Seamless Integration of MEP Systems — Plumbing and electrical systems were reworked to accommodate the new annex, kitchen & bathroom refurbishments, ensuring efficient layout and modern standards.

Comprehensive Renovation Under Single Management — Coordinating structural, plumbing, electrical, finishing and external works in one project — minimising disruption and ensuring consistent quality.
