# Garage Conversion Costs & Ideas for 2026

3 June 2026 · 5 min read

What it costs to convert a garage into living space in 2026, the best uses, and whether you need planning permission.

## What a garage conversion costs

**Converting an integral or attached garage typically costs £6,000–£20,000 in 2026.** A straightforward conversion of a single garage into a room runs around £6,000–£12,000; adding a bathroom, bi-fold doors or a kitchenette pushes it higher.

## Why it’s such good value

The walls, roof and foundations already exist, so a garage conversion is one of the cheapest ways to add a proper room — a home office, gym, playroom, snug or extra bedroom. Because you’re not extending the footprint, it’s far less disruptive than building from scratch.

## What the work involves

Typically: infilling the garage door with an insulated wall and window, raising and insulating the floor, insulating the walls and ceiling, and adding heating, electrics and ventilation to meet building regulations.

## Frequently asked questions

### Do I need planning permission to convert a garage?

Usually it falls under permitted development if you’re not enlarging the building, but conversions in conservation areas or on some new-build estates (which may have a condition to keep the garage) can need permission. It always needs building-regs approval.

### How long does a garage conversion take?

Most take **3–6 weeks** depending on spec and whether you’re adding plumbing.

### Will I lose value by losing the garage?

In most areas the extra living space is worth more than the garage, especially where off-street parking remains. Where a garage is prized, weigh it up — a specialist can advise.
