Indicative prices, not installed quotations. Cedar Spaces is VAT registered. Your quote will show the VAT breakdown, delivery, installation, foundations, services and final specification. A size shown here still needs a site and layout review. For other dimensions, ask about a bespoke design.
Options & example pricesSee the individual adjustments, then preview them on your room.
Each preview starts with this page’s smallest featured room and adds the chosen option. If a layout needs more space, its larger footprint and complete example total are shown below. These amounts use the same calculations as the customiser; they are not approved upgrade quotes.
Heating, internet or plumbing?
Tell us about heating and cooling, data connections, water and drainage, specialist sound isolation or equipment. These need a tailored specification and quotation; they are not priced in the options above.
Discuss your specificationMade for the way you live
A proper home for your next idea.
A central table is a flexible starting point for sewing, drawing or smaller making projects. Think about where you cut, assemble and store work, and how those activities change through the day.
Painting, ceramics and woodworking can have very different demands. Tell us about dust, heat, chemicals, water and heavier equipment so the room can be specified appropriately. A general garden-room layout is not a specialist workshop specification.
Open the customiserThe details that make a difference
Plan it around you.
Working surfaces
Choose table height and clearances around your own equipment, including cutting and assembly space.
Light & power
Combine useful daylight with task lighting and sockets where you need them.
Specialist activities
Extraction, a kiln, heavy tools or a utility sink require a separate technical discussion.
The Cedar approachConsidered from
Considered from
the ground up.
Your written quotation sets out exactly what is included. Cedar’s published specification provides the starting point.
- Design consultation and a bespoke plan
- Insulation for year-round use
- Electrics, lighting, plastered walls and flooring
- Glazing and a choice of exterior finishes
- Site-specific foundations: concrete or ground screws
- Build coordination and aftercare
Cedar publishes a 10-year structural warranty and a 20-year EPDM roof guarantee. Ask for the applicable terms with your quote.
Materials & construction details
- Insulation
- Year-round use is part of the brief. Your specification confirms the wall, floor and roof build-up, insulation thicknesses and thermal performance.
- Cladding & interior
- Choose the exterior finish, then agree flooring, wall finishes and any fitted joinery. Ask to see the proposed material samples and care guidance.
- Roof & drainage
- Confirm the EPDM roof specification, roof edges, any canopy, and gutter and downpipe positions on the final drawings.
- Doors & windows
- The customiser explores door styles and side glazing. Exact opening sizes, frame material, glazing performance and locks are agreed for your build.
- Electrics & lighting
- Agree socket quantities, lighting, heating loads and data needs. The quotation must identify the connection to the house, cable route and any trenching or extra work.
- Foundations
- Concrete foundations or ground screws are considered at the site visit. Ground conditions, levels and the intended load determine the final approach.
Exact technical values belong to your agreed specification. The visualiser does not establish insulation ratings, certified internal clearances or construction dimensions.
What do we confirm for your project?
Access and groundwork; exact foundations; electrical and internet connections; heating and ventilation; any water and drainage; interior fit-out; specialist equipment; tax treatment; the programme and warranty terms. Items are included only where stated in your written quotation.
Before the buildA little planning.
A little planning.
A better fit.
A few details about your garden help turn a starting design into a properly considered quotation.
01 · Space
Measure beyond the footprint.
The sizes shown are external room dimensions. Interior space is smaller once the walls and finishes are allowed for. Roof edges, gutters, decking and a canopy may extend beyond that footprint.
Share your available width and depth, boundaries, trees and any height restrictions. We’ll confirm internal dimensions and working space around the room in the drawings.
02 · Access & ground
Show us the route in.
Photographs of the garden and the access route are useful, including narrow gates, steps, changes in level and an existing base.
Discuss clearance and foundations with us before arranging groundworks. An existing concrete base needs review before it can be included in the design.
03 · Services
Plan the connections.
List the equipment you intend to use, where sockets and lights will help, and whether you need heating, cooling or wired internet.
Water, drainage and the electrical connection back to the house need a site-specific scope. Ask for these works, the programme and VAT breakdown to be clear in your quote.

From Cedar Spaces customers

We are really pleased with our garden room. Mix of gym and snug room. Brian worked with us to maximise the use of the plot and was also flexible with design as we worked through cabling and door choices later in the process. Good quality workmanship a done to time 👍🏼Google review
Highly Recommend! Brian and his team were informative, honest and prompt to handle any queries or updates. Whole thing was finished end to end in a couple of weeks and months on I couldn't be happier!Google review
Couldn’t be happier with how our cabin turned out; highly recommend.Google review
Before you begin
A little clarity.
Have a question about your own garden?
Talk it through with our team.
Can the room be used for sewing and painting?
Yes. Share how you work so surfaces, lighting, storage and ventilation can be considered together. Materials and equipment are not included in the base building guide.
Can I install a kiln or woodworking equipment?
Tell us the exact equipment specification before design. Electrical loads, heat, dust extraction and structural requirements need specialist review and separate pricing.
What does the starting price cover?
It is a base building guide calculated from Cedar’s published £1,250/m² starting rate, rounded up to the nearest £100. It is not a fixed installed price. Cedar Spaces is VAT registered. Your written quotation will show the VAT breakdown, foundations, services, installation, upgrades and specialist fit-out.
Can I use my garden room throughout the year?
Cedar’s rooms are insulated for year-round use. Heating, ventilation, glazing and the way you use the space are considered together in the final specification.
What about planning permission and building regulations?
The requirements depend on your property, location, dimensions and intended use. Check your project with the local authority before work begins. A customiser design does not establish permission or regulatory compliance.
How long does a build take?
Cedar’s published build guide is around one to three weeks for a straightforward room. Site preparation, specialist services and the agreed design can change the programme; confirm your start date and build schedule with the team.
Are the sizes internal or external?
The price examples and customiser show external room dimensions. Wall build-up reduces the usable interior, while roof edges, gutters, a canopy or decking may need additional space outside. Confirm exact internal dimensions, overall projections and access clearances in your agreed drawings.
Does the electrical package include the connection to my house?
Cedar’s room specification includes electrics and lighting, but the route, capacity, trenching and connection to your house depend on the site. Ask for the connection work, socket quantities and any additional electrical costs to be explicitly included in the written quote.
Should I prepare a base before ordering?
Speak to the team before arranging a base or groundworks. Cedar uses concrete foundations or ground screws depending on the project. An existing base, the garden levels, access and intended loads need to be reviewed at the site visit.
