The brief

An end-of-terrace house with an unused side passage and a small rear addition. The brief was more space on both floors: a two-storey extension up the side of the house and a single-storey extension across the back, finished so the new work reads as part of the original house.

Groundwork

The garden was cleared back to soil, the foundations dug and poured, and the drainage run in before the walls started. The new walls came up in blockwork off a brick course, with the rear door and window openings set out from the first lifts.

Building up the side

The side extension was built up to first floor level and on to its own roof. The existing roof was opened at the hip so the new roof could be tied into it, which is what keeps the roofline following the house rather than looking added on.

The finish

The whole rear elevation was rendered white to match the original house, with new white windows, French doors onto brick steps and a new dark paved patio, black rainwater goods and wall lights. The lawn was relaid last, once the site was cleared.

Behind the build

Process of work

The build as the client chose to show it: the finished house first, from the air and from the garden, then back through the blockwork going up on both floors to the groundwork where it started.

9 stages

  1. The rendered rear of a house with a two-storey side extension, a single-storey rear extension with French doors and brick steps, and a new lawn

    01Finished rear elevation

    The finished back of the house from the garden: white render throughout, French doors with brick steps down to the new patio, and the two-storey side extension with its new first floor window.

  2. Top-down aerial view of a terrace roof with a new hipped side extension roof and a flat rear extension roof above a striped lawn

    02From directly above

    Straight down from the drone: the new hipped roof over the side extension tied into the main roof, the flat roof across the rear extension, and the patio and lawn behind.

  3. Aerial view of a rear and side extension under construction in blockwork, with scaffolding and a cleared garden behind a terrace

    03Blockwork on both floors

    The build from above mid-way through: the rear extension walls up in blockwork, the side extension being built up to first floor, and the garden cleared as a working site.

  4. Wide aerial view over a house with a blockwork extension and scaffolding, looking across to the street and the houses opposite

    04Scaffold up

    A wider view of the same stage, looking over the house to the street, with the scaffold up and the first floor walls of the side extension going on.

  5. Builders laying blockwork for the first floor of a side extension, above a single-storey rear extension shell wrapped in scaffolding

    05First floor walls

    Closer in: the ground floor openings formed for the new doors and window, and the first floor walls of the side extension being laid from the scaffold.

  6. Two builders working on the first floor blockwork of a side extension next to an opened-up hipped roof

    06Building up the side

    The side extension rising alongside the original roof, which has been opened at the hip so the new roof can be tied in.

  7. A blockwork extension shell wrapped in scaffolding, seen from a cleared garden in low sunlight

    07From the garden

    The same stage seen from the bottom of the garden, with the ground floor shell complete and the scaffold carried up for the first floor.

  8. Builders raising blockwork walls for a rear extension against a semi-detached house, with a cleared muddy garden in front

    08Ground floor walls

    The ground floor walls coming up in blockwork off a brick course, with the rear openings set out and the drainage connection in the foreground.

  9. A cleared garden with the first brick courses of a new extension laid out against the back of a house

    09Foundations and first courses

    The start of the build: the garden cleared, the foundations in, and the first brick courses laid out on the footprint of the new extension.

Outcome

More room on both floors, and a rear elevation that looks as if it was always part of the house, handed back with a new patio and a relaid lawn.
