A calm, realistic way to estimate what a proper SIP garden room is likely to cost - with clear assumptions and
a breakdown you can send to me or compare against other quotes.
This is a guide, not a final quote. It's based on typical Helps & Co specifications in Surrey & Hampshire.
Site conditions, access and extras will always affect the final number.
1. Tell me roughly what you're thinking
Keep it simple - this doesn't need to be perfect. It's just to get into the right ballpark.
Left-to-right when looking at the front elevation.
Front to back into the garden.
This mainly affects finishes, glazing and time spent on detailing - not cutting corners on structure.
This doesn't include running services from the house - that's always priced on a site visit.
Bespoke flexibility
Got something more custom in mind?
Many premium garden rooms include bespoke glazing layouts, roof details, or site-specific considerations.
Your estimate remains a reliable guide - we simply fine-tune and confirm a fixed price on a site visit.
Custom glazing / bespoke arrangement
Some layouts can't be priced precisely without a quick site visit.
Your estimate is still a realistic starting point - final pricing is confirmed on survey.
Bespoke design note
Your estimate remains a reliable guide. We'll fine-tune the specification, access and site details during a free consultation and confirm a fixed price.

2. Guide build cost (supply & install)
Approx. -
Based on - and a - SIP specification.
Structure, SIPs & core materials-
Doors, glazing & cladding-
Electrics, heating & comfort-
Detailing, labour & overhead-
This is a guide only. Groundworks, access, service runs from the house, complex glazing, plumbing
and bespoke joinery are always confirmed after a site visit. I'd rather be accurate than guess.
Considering something more bespoke?
If your design includes custom features or you'd like us to confirm everything accurately, the next step is a short site visit.
We'll review access, layout and specification - then lock in a fixed price.
