What to Consider When Planning a Garage Conversion

If, like many of us, you never put your car in the garage and instead it's just a place to store a variety of 'rarely used items' (to put it politely!) you may have considered converting that space into a more usable part of the house. A good garage conversion can help to improve your quality of life and add value to your home, but what do you need to keep in mind? We run through the important points.

If, like many of us, you never put your car in the garage and instead it's just a place to store a variety of 'rarely used items' (to put it politely!) you may have considered converting that space into a more usable part of the house. A good garage conversion can help to improve your quality of life and add value to your home, but what do you need to keep in mind? We run through the important points.

Where do I start?

It's a great help if you already have an idea about what you would like the converted garage to be once it has been completed, whether that's a kitchen extension, kids' playroom, extra bedroom, utility room, office, gym, or whatever you may like. If you're interested in a quite significant development then contact an architect who can produce professional plans for you.

Who should I talk to about a garage conversion?

If you just want a simple conversion into a general purpose room then things are quite straightforward and any good builder should be able to help, though we recommend checking out reviews and examples of their previous work on TrustATrader.com as well as discussing the job in some detail to make sure you agree on what exactly will be done. If you have architect's plans, these can be used by the builder to create the new space.

Can I do the conversion myself?

It's possible to do much of a conversion task yourself if you have some experience of building work, but bear in mind that your work will need to be regularly inspected by a building control officer, and anything that doesn't meet regulations will have to be redone at your own expense.

Dealing with the door

The old garage door will need to be replaced with a wall or may include a window (normal height or floor to ceiling). New windows don't need planning permission but should be double-glazed and energy efficient to be approved by your local building control department. New foundations may be required; your architect or builder will be able to advise.

The roof

You may wish to change a flat roof to a pitched one, which can help make the conversion blend in better with the rest of the house. Remember that if you are doing more than a few repairs to the roof the work will need to be approved by building control.

Keeping ventilated

Bathrooms/shower rooms and kitchens must include extractor fans to meet regulations. For other purposes, an opening window and air bricks or trickle vents should be enough.

Insulation

Walls, windows, floor and ceiling need to be insulated to meet building regulations and to prevent the conversion becoming a cold, damp room. Rooms which will be occupied for long periods such as bedrooms and living rooms will need more insulation than a utility room or similar.

Keeping warm

Either run a new radiator from your existing boiler if possible, or if that's not practical you could try electric heaters, on the wall or underfloor.

Plumbing and Electrics

This work must be signed off by the building control department, so don't try to do this yourself unless you're a professional. It's worth getting several electrical sockets put in to make sure there are enough for any future use of the new room.

We hope this has helped if you're thinking of making better use of your own garage. Why not talk to some trusted builders, plumbers or electricians when you're ready?

  • What is the difference between a painter and a decorator?

    A painter focuses on applying paint - walls, ceilings, woodwork. A decorator does all of that but also handles wallpaper, specialist finishes, surface prep, and can advise on colours and materials. Many professionals do both and call themselves painters and decorators. For a straightforward repaint, a painter is fine. If you want wallpaper, something specialist, or someone to help you make decisions about the finish, go with a decorator.

  • How many coats of paint does a professional decorator apply?

    For most walls, it's a primer or mist coat, then two topcoats. New plaster, bare surfaces, or a big colour change might need more preparation or extra coats. Cutting corners on coats or using cheap paint are the most common ways to get a finish that looks fine at first and starts showing its age within a year. A trusted decorator always prepares the surface properly and won't rush between coats.

  • How do I prepare my home before a decorator arrives?

    Move furniture away from the walls and take down pictures, mirrors, and anything fixed to the walls. If you can strip old wallpaper yourself beforehand, it'll save time on site. Make sure every part of the room is accessible and well-lit. Talk through surface prep with the decorator in advance - a good one will tell you exactly what they need before they can start.

  • How do I know if my walls need replastering before decorating?

    If there are significant cracks, areas that sound hollow when you tap them, persistent damp, or large patches that are flaking or badly uneven - replastering first will give a much better result. Decorating over problem plaster looks fine initially but every imperfection tends to show through, especially with modern matt paints. A decorator can assess whether full replastering or careful preparation and skim coating will get you where you want to be.

  • What are the most popular interior design styles right now?

    There's been a pretty clear shift away from the all-grey, everything-neutral look of the 2010s. Warmer tones are dominating - clay, terracotta, stone, off-white - with natural materials like linen, rattan, and solid timber replacing high-gloss finishes. Biophilic design (plants, natural light, organic shapes) has gone from trend to standard practice. There's also a real appetite for spaces that feel personal and collected rather than showroom-ready - bold wallpaper, layered textiles, and period features being celebrated rather than painted over.

  • How long does a full home decorating project typically take?

    A single room in good condition typically takes a professional two to three days. A full house - particularly an older property that needs a little more care beforehand - can take several weeks. The part that often catches people off guard is the preparation: stripping wallpaper, filling, sanding, and priming all take a good amount of time, and doing them properly really does make all the difference to the finished result.
