Loft conversions

The extra bedroom is usually already inside your roof. We handle the structure, the staircase, the ensuite and the building control sign off, without a single subcontractor turning up unannounced.

Usually the cheapest room you will ever add

You already own the space, it already has a roof, and it rarely needs planning permission. What it needs is the structure done properly: floor joists sized for habitable load, a compliant staircase, fire separation and enough insulation to pass.

That is the bit people get wrong when they use four separate trades. We do all of it, so nobody is waiting on anybody.

  • Dormer and rooflight conversions
  • New staircase, built to regs rather than squeezed in
  • Ensuite plumbed and tiled by the same team doing the build
  • Insulation, fire doors and building control sign off

What it involves, honestly

Lofts are disruptive for a fortnight and then quiet.

  1. We measure the head height first

    Before anything else. If there is not enough height under the ridge, a dormer fixes it and we will tell you what that adds. If it genuinely will not work, we will say so rather than take a deposit.

  2. Drawings and building control

    Structural calculations for the new floor, then building control booked. Most conversions fall under permitted development, so planning is usually not needed.

  3. Structure and roof

    The noisy fortnight. Scaffold up, new floor in, dormer framed and made watertight, windows in.

  4. Staircase, ensuite and finishing

    Stairs, plumbing, plastering, second fix carpentry and decoration. Site cleared at the end of each day.

  5. Sign off

    Building control inspect and certify, and you get the paperwork for when you sell.

“They always cleared up after themselves, and they treated our home like a home. It wasn’t just a building site.”
Anne, Goring-by-Sea.

Worth saying, because a loft conversion means people going up and down your stairs for weeks.
