What Affects Garden Room Cost?

Every build is different. These are the factors that most commonly move the final price up or down:

• Size and layout complexity
• SIP construction vs timber framing
• Glazing systems (bifold, sliding, fixed panels)
• Foundations and ground conditions
• Access constraints on Surrey properties
• Specification level and internal finishes
• Electrical and data requirements
• External cladding choice (cedar, composite, render)
