Base building guides for garden games room concepts. Width runs across the front; depth runs from front to back. Figures use external room dimensions, not usable internal floor space.
Shallower rooms start with table games & consoles. Depths of 4 m and above start with the pool-table concept; equipment clearance still needs review.

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.
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.
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 specification
A pool table needs room around every playing edge, not just enough space to fit the table itself. Give us the model, outside dimensions and cue length before settling on a room size. The measurements below are external footprints; wall build-up reduces the usable interior.
For console gaming or an arcade room, think about screen glare, viewing distance, power and wired internet. A bar or sofa can share the space, provided it leaves the playing area clear. The customiser shows a starting layout to refine with our team.
Open the customiserConfirm the table maker’s playing-space requirements. The illustrated table is a layout cue, not a fit guarantee.
Plan socket locations and the route from the house for internet and power before the build.
Choose an open layout or, with enough width, a separate lounge. Tell us if you also want a bar or WC.
Your written quotation sets out exactly what is included. Cedar’s published specification provides the starting point.
Cedar publishes a 10-year structural warranty and a 20-year EPDM roof guarantee. Ask for the applicable terms with your quote.
Exact technical values belong to your agreed specification. The visualiser does not establish insulation ratings, certified internal clearances or construction dimensions.
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.
A few details about your garden help turn a starting design into a properly considered quotation.
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.
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.
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.

That depends on the game. Pool needs the table dimensions plus cue and player clearance on every side. Console and board-game layouts work differently. Send your equipment dimensions so we can check usable internal space.
Both can be discussed as bespoke additions. They require space, and a WC or wet bar also needs suitable services. These additions are not included in the base guide or certified by the visual layout.
No. Pool tables, arcade machines, screens, consoles and loose furniture are shown for inspiration and are priced separately from the garden building.
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.
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.
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.
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.
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.
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.
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.
Share an idea, a target budget or your preferred size. We’ll help shape the details.
