Local Garage Conversion Specialists Serving Altrincham and the WA14 and WA15 Area
Altrincham has a huge number of homes with a garage that hasn't seen a car in years — large inter-war semis and detached houses in Bowdon, Hale and Timperley, and post-war family homes in Broadheath and Oldfield Brow. If yours is full of boxes, bikes and things you'd forgotten about, a garage conversion is the quickest and most cost-effective way to add a proper room to your home without the upheaval of moving or the cost of an extension.
Our Altrincham team handles the whole project from the first survey to the completion certificate. We remove the garage door and build an insulated, brick-matched infill wall, raise and insulate the floor, dry-line and insulate the walls and ceiling, fit new electrics, heating and windows, then plaster, floor and decorate to match the rest of your house. Every stage is signed off by Trafford Council Building Control, so your new room is legal, warm and ready to be counted as living space when you come to sell.
Whether you need a bedroom for a growing family, a quiet home office , a gym , a playroom , a utility room or a self-contained annexe for a relative, we'll design the space around how you actually live. We also cover Sale, Wythenshawe, Urmston, Stretford, Chorlton, Gatley and the surrounding villages.

Garage Conversion Ideas for Altrincham Homes
Whatever room your Altrincham home is missing, there's a good chance it's sitting behind your garage door. These are the conversions we're asked for most.
Garage to Home Office
A quiet, insulated workspace away from the kitchen table, with proper lighting, power and data points so working from home actually works.
Home office conversions
Garage to Annexe
Self-contained living for an elderly parent, an adult child or a lodger — with kitchenette, shower room and its own entrance where possible.
Annexe conversions
Garage to Home Gym
Reinforced rubber flooring, ventilation, mirrors and plenty of sockets — a gym you'll use because it's twenty steps from the kettle.
Home gym conversions
Garage to Playroom
Give the kids somewhere to spread out and reclaim your living room. Warm floors, safe electrics and easy-clean finishes as standard.
Playroom conversions
Garage to Utility Room
Move the washer, dryer, boots and dog beds out of the kitchen. Plumbing, drainage and storage designed in from the start.

Altrincham FAQs
Garage Conversion Questions from Altrincham Homeowners
The questions we hear most often on first visits around Altrincham. Have another? See the full FAQ or give us a call on 0161 985 0645 .
Do I need planning permission for a garage conversion in Altrincham?
Usually not. Converting an attached garage into a habitable room is normally permitted development, so most Altrincham homeowners don't need a planning application. You will need one if your home is listed, in a conservation area, has had permitted development rights removed (common on newer estates) or if you're converting a detached garage into separate accommodation. We check with Trafford Council on your behalf before any work starts.
Does a garage conversion in Altrincham need Building Regulations approval?
Yes — every garage conversion must comply with Building Regulations for structure, damp-proofing, insulation, ventilation, fire safety and electrics. We submit the Building Notice to Trafford Council Building Control, arrange the inspections and make sure you receive the completion certificate you'll need when you sell.
How much does a garage conversion cost in Altrincham?
Most single garage conversions in Altrincham cost between £8,000 and £15,000 depending on the room type, the condition of the existing garage and whether plumbing is needed. Double garages, annexes and conversions with en-suites cost more. Your quote is fixed-price and itemised, so you know exactly what you're paying for.
How long will my Altrincham garage conversion take?
A typical single garage conversion takes two to three weeks on site. Larger projects such as double garage conversions or annexes with kitchens and bathrooms usually take four to six weeks. We agree a programme with you before we start and keep disruption to a minimum.
Which areas around Altrincham do you cover?
Our Altrincham team covers the WA14 and WA15 postcode areas and the surrounding neighbourhoods, including Sale, Wythenshawe, Urmston, Stretford, Chorlton. If you're a little further out, get in touch — we cover the whole of Greater Manchester, Lancashire and Cheshire.
Will a garage conversion add value to my home?
A well-built garage conversion generally adds more value than it costs, because it turns dead space into an extra bedroom, office or living room. In Altrincham, where family homes with an unused garage are common, buyers consistently pay more for the additional usable floor area — and a proper Building Regulations certificate makes the sale straightforward.
