Example garden room prices by size

These examples are a guide only. Final price is determined by overall size, shape, specification, groundworks, access and location. Browse our gallery to see real, completed bespoke projects.

What affects your garden room price?

Because every Timber Rooms design is bespoke, the final price depends on a combination of factors:

• Overall size and shape - larger footprints and non-standard shapes increase material and labour costs.
• Cladding choice - cedar, larch and composite cladding sit at different price points.
• Doors and glazing - UPVC French doors are more economical than aluminium bi-fold doors.
• Groundworks and access - site preparation and how easily materials can reach your garden both affect cost.
• Location - travel and site-specific factors can influence the final figure.

A thorough site survey is the only way to give you an accurate, tailored quote but the examples on this page show what real projects typically cost.
