More room in the house you already love: surveyed properly, drawn clearly, and built to a schedule you can pin to the fridge.

Chapter I

The house you have

Most of the families we work with love their street, their school run and their neighbours. What they don’t love is eating in the hallway because the kitchen is two metres too short.

So we start where you are. A terrace like this one has a solid rear wall, joists that run front to back, and a garden that can usually give up four metres without anyone missing it.

We work across Leeds, Harrogate and the Aire Valley, on terraces, semis and 1930s houses.

Chapter II

Measure

Before anyone mentions a price, we measure everything: every wall, every floor height, the drains under the patio and the neighbour’s boundary.

A laser survey takes a morning. You get the drawings whether or not you go ahead with us, because a good drawing is useful to anyone.

Chapter III

Draw

Now the good part. Drag the back wall on the drawing and watch the room appear.

The blue outline is a single-storey rear extension with a rooflight over the table. As you move the wall, the plate recalculates the new floor area, and tells you which planning route that depth usually needs.

In England, a single-storey rear extension on a terraced house can usually go up to 3 m under permitted development, or up to 6 m with prior approval from the council. We check your house’s own rules before we draw.

Chapter IV

Build

A typical single-storey extension takes about twelve weeks on site. You get the schedule on day one, and a message every Friday saying where we are against it.

  1. Weeks 1–2Groundwork, drainage and foundations
  2. Weeks 3–5Walls, steel beam and opening up
  3. Weeks 6–7Roof, rooflight and weatherproofing
  4. Weeks 8–9Doors, windows and first fix
  5. Weeks 10–12Plaster, kitchen, floors and snagging

A typical schedule for a concept project; every real job gets its own.

Chapter V

Live

Then it’s just your kitchen. Light over the table, the garden at the end of it, and room for everyone at once.

We come back at six months to adjust anything that has settled, and our workmanship is guaranteed for ten years.
