A garage conversion company that handles every stage for you

Plenty of Chelmsford garages were built for cars far narrower than the ones on the drive today, so they end up holding bikes, boxes and the chest freezer instead. Converting it adds a genuine room for far less than an extension would cost, because the shell of the building (walls, roof and foundations) is already standing.

The skill is in the parts you never see. The floor usually sits below the house and needs raising and insulating; the walls and roof need insulating and damp-proofing; and the old door opening has to be built in so it matches the front of the house. Get those right and nobody would guess the room was ever a garage.

We are B UK Property Services, an Essex building firm with more than 20 years spent redeveloping homes and an endorsement from Which? Trusted Traders. If you are planning a garage conversion in Chelmsford, whether you live in Springfield, Chelmer Village, Great Baddow, Writtle or Broomfield, we check the planning position and arrange the building regulations inspections for you, so you are never left dealing with the paperwork on your own.

What should your garage become?

Choose a room and imagine it where the boxes and bikes are now. Most Chelmsford garage conversions need no planning application, and we confirm the position for your home on the first visit.

Home office

Swap the kitchen table for a proper workspace: insulated, well lit and wired for screens, with a door that closes on the working day.

  • Comfortable to work in, winter and summer
  • Power and data where the desk will sit
  • Daylight through glazing in the old door opening

Snug or playroom

A second sitting room for film nights, homework or the teenagers, so the main living room gets to stay tidy for once.

  • Opens straight off the house
  • Warm, softly lit and ready for evenings
  • Decorated to match the rooms around it
Get a snug quote

Guest bedroom

Somewhere proper for family and friends to stay, instead of an airbed in the study, in space you already own.

  • A downstairs bedroom that stays dry and warm
  • Built to current building regulations
  • Far less outlay than building an extension

Annexe

Room for a parent or grown-up child to live close by with some independence: sleeping and sitting space, with a shower room where the drainage allows.

  • Independence without moving away
  • Shower room or WC if the drains allow
  • Planned around whoever will live there

Something else in mind? We also convert garages into utility rooms and home gyms, and convert just part of a garage or the whole of a double one.

Garage conversions built properly, not patched together

A converted garage should be as warm, dry and solid as the rest of your house. That comes down to doing every stage properly, and being straight with you about what it will take.

  • One team, survey to finish

    We look after the building work, electrics, heating, plastering and decorating, so nothing falls between separate trades and there is always one person to call.

  • Straight answers from the start

    A written, itemised quote and honest advice about what your garage can become, including the options that save you money.

  • Built to match your house

    The old door opening is built in to match your brickwork or render, so from the street it looks like it was always that way.

  • Warm and dry for the long run

    Insulation, damp proofing and ventilation done to current standards: the stages that cheaper conversions skip, and the ones that matter most in January.

Ten years of cover on your garage conversion

Once you have paid the final invoice, an insurance-backed guarantee covering the whole contract price protects your conversion, and that protection stays with you long after the builders have gone.

For garage conversions the guarantee runs for a full decade, matching the term we offer on extensions, loft conversions, glazing and garage doors.

From cluttered garage to finished room in four steps

No jargon and no chasing. This is how a garage conversion with us unfolds, from first call to finished room.

  1. Share your idea

    Ring, WhatsApp or fill in the form. A rough plan is fine; a couple of photos help, but drawings aren’t needed.

  2. A visit and survey

    We look at the floor, walls, roof and any damp, see how far your heating and electrics can reach, and talk through the options.

  3. Your written quote

    Each stage priced separately, with realistic dates. It costs nothing and commits you to nothing.

  4. Built by one team

    From removing the garage door to the last lick of paint, followed by building control sign-off and your 10-year guarantee.

The first step takes about a minute.

I can not recommend B.UK highly enough. From the detailed, incredibly reasonable quote to the high quality of the work done, to the attention to small details and constant communication we had, they provided us with a fantastic double garage conversion. Nothing was too much trouble and they completed the work in less time than first quoted. I would use them again for any work we need. They are outstanding!

Double garage conversionLeft on Which? Trusted Traders

Lee and his team were really professional and have completed a high quality job on our bathroom renovation and garage conversion. Would certainly recommend and use for any future work.

Bathroom renovation & garage conversionLeft on Which? Trusted Traders

The quality of work has always been excellent, and the level of communication always top quality, starting with very clearly broken down quotes, through to ongoing consultation through the project. On top of the quality and value of the work, they are also great people — friendly and open, which helped build trust very quickly. We’ve used Lee and Marty for three fairly significant jobs now and we wouldn’t hesitate to use them again.

Three projects over three yearsLeft on Which? Trusted Traders

B.Uk have carried out numerous projects at my property over the last few years from a complete kitchen refit to converting a bathroom to a wet room. Builders like Lee and Marty are hard to find, Which is why they are always my go to guys for the jobs that require the experts!

Do I need planning permission to convert my garage in Chelmsford?

In most cases, no. Turning an integral or attached garage into a habitable room normally counts as permitted development, provided the changes are internal and the footprint stays the same. Chelmsford City Council handles planning locally, and an application becomes more likely if your home is listed, lies within a conservation area, or was built with a condition requiring the garage to stay available for parking — something found on some newer estates. We check the planning history for your address before anything starts.

Is building regulations approval needed for a garage conversion?

It does. Using a garage as living space counts as a change of use, which brings in building regulations for insulation, damp, ventilation, fire safety, structure and electrics. We book the inspections at each stage and pass you the completion certificate once the room is signed off — a document a buyer’s solicitor will want to see if you ever sell.

What will a garage conversion in Chelmsford cost?

There is no set price, because each garage is different: its size, how far below the house the floor sits, the condition of the walls and roof, whether your heating system has capacity to spare, and whether you want a WC or shower. After a free visit we send a written quote that prices every stage separately, so you can see where the money goes. Asking for one costs nothing and commits you to nothing.

How long does a garage conversion take?

That depends on the garage and the room it is becoming — a single garage turned into a study is a quicker job than a double garage becoming an annexe with a shower room. Your quote includes dates we can genuinely meet, and we keep in touch with progress throughout.

Do you cover my part of Chelmsford?

Yes, if you are in a CM1, CM2 or CM3 postcode — the city centre, Springfield, Broomfield, Writtle, Great Baddow, Galleywood, Chelmer Village, Danbury, Boreham, South Woodham Ferrers and the villages in between. Use the postcode checker on this page, or ring 01206 205285 for a quick answer.

Is my garage conversion guaranteed?

Yes. Once the final invoice is paid, the work is covered by insurance-backed protection for the whole contract value; for a garage conversion it lasts ten years.

Are you accredited?

We are endorsed by Which? Trusted Traders with a five-star rating, following an independent check of our work, our customer care and the way we run the business.
