ITM Brickwork builds brick and blockwork for house extensions across London and surrounding areas, properly connecting the new living space with the existing property.

We work with homeowners, builders, architects, developers, and main contractors on rear extensions, side return extensions, single-storey extensions, double-storey extensions, and larger residential improvement projects.

Clients often come to us with reference images showing the kind of house extension, brick finish, or layout they would like to achieve.

The examples below are for inspiration and illustrate the types of extension brickwork, blockwork, wall finishes, and structural details ITM Brickwork can deliver. Real completed and in-progress ITM Brickwork projects are shown further down this page.

Why choose ITM Brickwork for your house extension?

House extension brickwork requires careful alignment with the existing property, consistent coursing, and close attention to brick and mortar matching. ITM Brickwork focuses on clean junctions, correct tie-ins, and straight, level walls so the new extension integrates naturally with the original building.

We also understand how brickwork fits into the wider build, including openings for steelwork, floor levels, roof structures, and other site requirements. With careful setting-out and controlled execution, we help deliver durable, well-finished extension brickwork that supports the project from structure through to final appearance.

This gives homeowners and contractors a reliable brickwork partner focused on workmanship, coordination, and a clean finished result.
