What we build

Four ways we work on a home.

Whatever the scope, you get one team, one contract and one point of contact — from planning drawings to the final handover.

  • Extensions

    Single and double-storey, rear, side-return and wrap-around. Steel, glazing and the structural work to open a house up — designed, engineered and built by us.

  • Renovations

    Full and partial refurbishments — rewires, replumbs, replastering, new floors and joinery. Tired houses taken back to brick and rebuilt to last.

  • Kitchens

    Kitchen design and installation, knocking through, islands, utility and boot rooms. Handmade and trade units fitted to the millimetre.

  • Whole-home

    Whole-house renovations and remodels, loft conversions and reconfigurations — the big projects, project-managed from end to end.

Why Halloway Build

The reasons owners trust us with the big ones.

A renovation is months of your life and a lot of your money. We run ours so you always know the price, the programme, and exactly who is in your home.

  • Fixed quotes

    The price we quote is the price you pay. A full written breakdown before we start — no day-rate surprises, no creeping extras.

  • A programme you can hold us to

    A dated build programme from day one, updated every week. If a date has to move, you hear it from us first.

  • Guaranteed work

    Every project carries our 10-year structural guarantee and an insurance-backed warranty. Certified, signed off, yours to keep.

  • One team, one contract

    Our own carpenters and site managers run the job — one firm accountable from the first drawing to final handover.

How we work

Four stages, no surprises.

The same process on every job, whether it's a new kitchen or a whole house. You always know what happens next.

  1. Consult

    We visit, listen to what you want and talk budget honestly. If we're not the right firm for the job, we'll tell you.

  2. Design

    Drawings, structural calculations, a fixed quote and a build programme. Planning and building control handled for you.

  3. Build

    Our team on site, tidy and on schedule. A weekly update, one site manager, and your home protected throughout.

  4. Handover

    Snagging done properly, everything certified and signed off, guarantees in your hands. We're a phone call away after, too.

  • They quoted £145k for our extension and £145k is exactly what we paid — to the penny. Twelve weeks, run like clockwork, and the finish is better than we dared hope.
    Sarah & Mark T. Rear extension · Clifton
  • Our house was chaos for four months and Halloway made it painless. Same site manager every day, swept up every night, and they rang us before problems became problems.
    James P. Full renovation · Redland
  • We'd been let down by two builders before. This lot turned up when they said, finished when they said, and every guarantee was in the folder at the end. Faultless.

Good to know

The questions owners ask first.

Timelines, quotes, guarantees and living through a build — the honest answers before you commit.

How long does a project take?
It depends on scope, but as a guide: a kitchen fit is 3–5 weeks, a rear extension 10–16 weeks, and a whole-house renovation 4–9 months. You'll get a dated programme with your quote and a weekly update once we're on site, so you always know where things stand.
How does the quote work — is it really fixed?
Yes. After a visit and drawings we give you a full written quote broken down by trade and stage — that's the price you pay. The only thing that changes it is a change you ask for, agreed and priced in writing before we do it. No day rates, no vague 'provisional sums' that balloon at the end.
What guarantees and insurance do you have?
We carry £5m public liability insurance, and every project comes with our 10-year structural guarantee plus an insurance-backed warranty — so you're covered even in the unlikely event we're not around. All work is certified and signed off by building control, and you keep the full paperwork.
How disruptive is it to live through?
We won't pretend a build is invisible, but we keep it civilised: dust screens up, floors protected, the site swept every evening and one site manager as your single point of contact. For bigger jobs we agree which rooms stay usable and when — and for whole-house projects, many owners move out for the messiest stretch.
Do you handle planning and building regs?
Yes — it's part of the design stage. We prepare the drawings and structural calculations, submit for planning or a lawful-development certificate where needed, and manage building control inspections through to sign-off. You don't chase the council; we do.
