Extension · Amsterdam e.o. · 2026

Brick extension with full-width sliding doors

A timber frame with a brick outer skin matching the house, three-panel white sliding doors and a flat roof: an extension that looks as if it had always been there.

The finished extension from the garden: brickwork, white three-panel sliding doors and a flat roof, with the house’s dormer above
From the garden: full-width sliding doors, brickwork in the house’s own brick.Completed

The situation

A terraced house with a dormer and a narrow side path along the garden. The rear wall was a single door and a window; the kitchen and living room shared a space that was too small for both. The wish: one big living space on the garden, with as much glass to the outside as possible.

What was done

  • New foundation and concrete floor
  • Timber frame with PIR insulation in the walls
  • Brick outer skin in the same brick as the existing house
  • Three-panel sliding doors in white uPVC, across the full width
  • Flat roof on timber joists with a steel beam over the doors
  • Side path reinstated and joined to the existing boundary fence

Doors
Three-panel, white

The result

The doors run wall to wall, so the entire back of the house is now garden. Because the outer skin is laid in the same brick, from the side path the extension does not read as an add-on but as the house itself.

Projects

Before, during and after

  1. The extension’s timber frame with the sliding doors already fitted and pallets of bricks beside itDuring
    The frame is up and the doors are in; the bricks are ready for the outer skin.
  2. The extension’s rear wall with the white sliding doors, seen from the terraceAfter
    Brickwork and doors complete. The roof edge is finished last.

More photos of this project

  • PIR insulation boards on the side wall of the timber frame, along the side path
    Insulation on the frame, before the brickwork: this is what keeps an extension warm.
  • The side wall’s brickwork halfway up, with the insulation still visible above it
    Rising brickwork: the outer skin grows course by course against the insulation.
  • The narrow side path during the build, with the extension’s brickwork and the fence
    Working in a side path a metre wide: a terraced house demands planning.
  • The finished side wall of the extension along the side path
    The same wall, finished: the new brick runs in one line with the house.
