Frequently Asked Questions
How much space for an office?
Minimum 2m × 3m for desk and chair. 3m × 4m for full office setup with storage and video call space.
Air conditioning worth it?
Yes for full-time home workers. Summer heat distracting; winter cold equally so. Split AC unit £1,200–£3,500.
Built-in or freestanding desk?
Built-in: maximum storage, custom fit. Freestanding: flexible, movable, cheaper. Built-in for permanent home office; freestanding for flexible use.
Will home office add value?
Yes — post-pandemic, dedicated office adds 3–7% to property value. Cleaner than "spare bedroom" in marketing.
Office and bedroom in one room?
Possible — sofa bed for guests, fold-away desk. Less ideal than dedicated. Limits both functions slightly.
Best floor for an office?
Hard floor (wood, LVT) preferred over carpet for chair castors. Add area rug for acoustic and warmth.
