Answers to common questions about our Garden Offices in Worthing
Do I need a concrete base for my garden office?
Yes, a solid foundation is vital. For most permanent garden rooms, we recommend a reinforced concrete slab or a heavy-duty timber frame base. This prevents the building from sinking or warping over time. We handle all the groundworks and foundation pouring as part of our service.
Can I use my garden room as an office all year round?
Absolutely. We build our garden studios with high-performance insulation in the floor, walls, and roof. When combined with double glazing, the building retains heat incredibly well, making it a comfortable place to work even in the middle of winter.
How long does it take to build a bespoke garden studio?
While every project is different, most garden offices are completed within 2 to 4 weeks once the groundworks are finished. Because ER3 Group LTD manages the start-to-finish process, we keep the project moving without waiting for outside subcontractors.
