How do you convert a garage into a playroom?

A playroom has to be warm, safe and tough enough for small people. Here are the questions parents ask.

Is the glass safe for children?

A new insulated wall replaces the garage door, with a window to let the daylight in. Any glass low enough for a child to fall against is toughened or laminated safety glass, as building regulations ask.

Will the floor be warm enough to play on?

Children spend their time on the floor, so it matters most. The cold concrete gets a damp-proof layer and insulation, then a new floor raised to the level of the house. Carpet or soft vinyl goes on top, and with underfloor heating there is no hot radiator to bump into.

A builder fitting insulation into a ceiling.

Will we hear them from the lounge?

Walls and ceiling are insulated to building regulations, so the room stays warm all year. The new plaster and insulation also take the edge off the noise next door.

Are the sockets safe?

Sockets go where the lamp, the TV and the games console will stand. Every new one is protected by an RCD, a switch that cuts the power in a split second if something goes wrong.

What about fire?

Building control checks fire safety too, which can mean a fire door to the house and smoke alarms wired to the mains. That way the playroom is as safe as any other room.

An inspector checking the inside of a house.

Will it be signed off?

Building control inspects the work in stages and issues a completion certificate at the end. Keep it with the house deeds: you will need it when you sell.

A playroom now, a den later

A smaller single garage is about 2.2 by 4.7 metres once the walls are lined. That is room for a big play mat, a wall of toy storage, a table for drawing and a chair for stories.

Children grow, and the room grows with them. The same space makes a den or games room with a sofa, a TV and a desk for homework. Tap between the two plans to see both.

How much does it cost to convert a garage into a playroom?

A playroom in a single garage usually starts from around £12,000, VAT included. It is built like any other room in the house, so it is ready for whatever it becomes next. Flooring and storage are chosen with you and added to your written price.

Do I need planning permission to turn my garage into a playroom?

Planning permission: usually not needed

39 of 41approved when people applied

A playroom inside your own house rarely needs an application. Where people did apply, councils said yes to 39 of the 41 decided applications that named a playroom, across eight West Midlands councils from 2016 to October 2026.

Building regulations: almost always needed

£570

A playroom is a room people use every day, so building control checks it like any other: insulation, safe glass, ventilation, wiring and a way out in a fire. Solihull Council's fee for a single garage is £570, and it is already in our prices.

Planning figures from council records collected by PlanIt for Solihull, Birmingham, Coventry, Bromsgrove, Redditch, Warwick, Stratford-on-Avon and North Warwickshire. Most conversions need no application at all, and many of these applications included an extension too, so read them as a sample. Fee from Solihull Council's 2026 to 2027 fee list.

Ask us a question

How much would it cost to convert a garage into a playroom?

Usually from around £12,000 for a single garage, VAT included. That covers the new wall and window, the floor, insulation, heating, power and sign-off. Converting just the back half, with storage kept at the front, usually starts from around £9,000.

Can the playroom become something else later?

Yes. It is built to the same standard as any other room in the house, so it can turn into a den, a games room, a home office or a spare bedroom as the children grow. Tell us what you might want later and we will plan the window and door with that in mind.

Will converting the garage put my council tax up?

Not straight away. The Valuation Office Agency only looks at your band again when the house is next sold, or if every home is revalued. Until then, your band stays the same. What the Valuation Office Agency says.

Can I keep part of the garage for storage?

Yes. An insulated, fire-resisting wall goes across the garage, with the playroom at the back and bikes and garden toys at the front behind the garage door. It usually starts from around £9,000. Half garage conversions.

Can I add a toilet for the children?

Yes. A downstairs WC with a toilet and basin typically adds £3,000 to £5,000, depending mostly on how far the garage is from the drains. It saves a lot of trips upstairs.

How long does a garage playroom conversion take?

Most single garage playrooms take two to four weeks on site. Adding a WC or knocking through into the house takes longer. The visit is the time to ask how long yours will take.
