Garage Conversions in Crawley, East Grinstead & West Sussex
Turn an underused garage into a room that works for the way you live. Oak & Stone Carpentry and Building LTD creates garage conversions for homeowners in Crawley, East Grinstead and the surrounding area. Whether you need a quiet home office, an extra bedroom, a gym or more family space, we bring the building work and detailed carpentry together to make the finished room feel at home in your house.
What Can You Convert a Garage Into?
A converted garage can give you a dedicated room without extending the footprint of your home. We plan the space around its intended use, with attention to warmth, natural light, practical services and the final finish.
Garage to home office
Create a quieter place to work with suitable lighting, power and storage. A built-in desk or fitted cabinetry can make the most of a compact room.
Garage to bedroom
Gain a comfortable extra bedroom for family or guests. We consider insulation, ventilation and layout from the start; an en-suite can be discussed where space and drainage allow.
Garage gym or playroom
A gym needs space for your equipment, while a playroom benefits from durable finishes and storage. We can discuss floor construction, ventilation, lighting and heating for year-round use.
Garage Conversion Types, Costs and Approvals
Single, double and partial conversions
A single garage can become a compact office, bedroom or family room. A double garage offers more flexibility, while a partial or half conversion may let you keep useful storage. We assess the available dimensions and existing building before recommending a layout.
Integral, attached and detached garages
An integral or attached garage may offer a more direct connection to the house. A detached garage needs careful thought about access, insulation, heating and services. The right approach depends on its structure and intended use.
What Is Included in a Garage Conversion?
The work depends on your garage and the room you want. A project may involve adapting the garage door opening, new brickwork or windows, structural work where needed, floor construction, insulation, ventilation, electrics, heating, plastering, flooring and decoration. Plumbing, partitions and bespoke joinery can be included when they are part of the agreed plan. Your quotation will set out the scope for your property.
How Much Does a Garage Conversion Cost?
Garage conversion costs vary with the size and condition of the existing building and the finish you choose. A straightforward single garage office will have different requirements from a double garage conversion or a bedroom with an en-suite. A useful estimate starts with an assessment of the actual space.
What affects the price?
Key factors include the condition of the floor and structure; the amount of insulation and ventilation required; replacing the garage door; new windows and external doors; electrical work; heating; plumbing and drainage; and the final flooring, decoration and fitted carpentry. Structural changes or a bathroom can add substantially to the work.
We can inspect your garage, discuss your plans and provide a free, no-obligation quotation based on the agreed scope.
Do You Need Planning Permission?
Planning permission is not always required to turn a garage into living space for the existing home, particularly when the work is internal and the building is not enlarged. It depends on the property. Planning conditions may require the garage to remain available for parking, permitted development rights may be restricted, and changes to the outside of the building or a listed property can affect what is needed. Check the position with your local planning authority before work begins.
Do Garage Conversions Need Building Regulations Approval?
Converting a garage into a habitable room normally requires Building Regulations approval. Building Control may consider the structure and floor, insulation, damp protection, ventilation, fire safety, windows and doors, electrics and any drainage. Planning permission and Building Regulations approval are separate matters. We discuss the practical requirements early so the new room is planned as proper living space.
Carpentry That Completes the Room
Our carpentry background helps us make the converted space feel connected to your home. We pay attention to doors, skirting, architraves, window boards, flooring and clean junctions. Where useful, we can discuss fitted storage, cabinetry or a built-in desk designed around the room. The aim is a comfortable, functional room with a considered finish.
Explore our built-in wardrobes and bespoke fitted carpentry services for ideas that could complement your new room.
A Managed Conversion From Start to Finish
Tell us how you want to use the space. We assess the garage and discuss the layout, services, finish and any approval questions. Once the scope is agreed, we provide a quotation and coordinate the work needed to turn the space into a finished room. You deal directly with the person building your project and can discuss details as the work progresses.

Garage Conversion FAQs
How long does a garage conversion take?
The timescale depends on the building and the amount of work involved. Structural changes, services, an en-suite and custom joinery can all affect the programme. We can discuss an expected timeframe after assessing your garage.
Can you convert a detached garage?
A detached garage may be suitable, but its structure, access, insulation and services need careful assessment. We can discuss what is practical and which approvals may be needed.
Can I convert only half of my garage?
A partial conversion may allow you to keep some storage while gaining a new room. It depends on the garage dimensions and a workable layout for both spaces.
Can a garage conversion include a bathroom?
It may be possible, subject to space, plumbing, drainage and approvals. Let us know early if a bathroom or en-suite is part of your plan so it can be included in the assessment and quotation.
Can the outside match my house?
The former garage door opening and any new windows or doors can be planned with the existing house in mind. Materials and finish depend on the property and any planning requirements.
