Most garden offices in Carshalton fall between £12,000 and £35,000+, depending on size, insulation level, glazing, electrics, heating and finishes. A compact office with standard cladding and basic power points sits at the lower end, while larger bespoke designs with upgraded sound proofing, premium doors/windows and more complex foundations cost more. We’ll survey your garden and provide an itemised specification so you can compare like-for-like.
Typical build time is 2–6 weeks from the start of groundworks to final fit-out, depending on the design and site access. Foundations and drainage can add time, especially after heavy rain or where levels need adjusting. Bespoke joinery, large glazing, or extra sound proofing and security upgrades can also extend the schedule. We confirm lead times for materials and agree a clear programme before work begins.
