The room needs to work for…

The existing garage

Read the building before drawing the finish.

An initial assessment should distinguish a sound shell from issues that could change the design or make conversion uneconomic.

Garage type recorded: integral, attached or detachedInternal dimensions and headroom measuredRoof, walls and floor checked for visible defectsSigns of damp, leakage or movement recordedGarage-door opening and proposed access consideredRoutes for power, heating, water and drainage considered

Pause point

If the shell has significant movement, persistent moisture, poor headroom or extensive rebuilding needs, obtain suitable professional input before treating conversion as the economical answer.

Scottish approvals

Resolve permission and responsibility early.

Planning permission and a building warrant are separate systems. Confirm the position for the particular property and proposal before work begins.
