A standard garden office works well for most requirements — but when your plot, your brief, or your working life demands something different, bespoke is the only honest answer. We design and build fully custom garden offices across Surrey from scratch: any shape, any footprint, any combination of glazing and materials. Whether it's an L-shaped office to fill an awkward corner, a soundproofed therapy room, a client-facing studio, or a large home office with its own meeting space — we start with your requirements and build around them.
Wired for Productivity
Cat6 data cabling, dedicated consumer unit, USB sockets, USB-C charging points — designed around how you actually work.
Acoustic Performance
SIPs construction delivers natural sound attenuation. Add acoustic wall panels and specialist insulation for call-centre quiet.
Year-Round Comfort
SIPs insulation keeps the room warm in winter and cool in summer. Add air conditioning or a smart panel heater for precise climate control.

Floor-to-ceiling glazing, roof lights, glass corners — we design the window and door layout around your orientation and working preference.

Garden Office Types We Build
Every project starts as a conversation about how you work and what your garden allows.
Why Choose a Bespoke Garden Office?
Working from home has changed what people expect from a home office. A spare bedroom or a corner of the kitchen table doesn't cut it when you're on client video calls, managing a team, or running a business. A bespoke garden office gives you a dedicated, professional workspace — separate from the house, designed around how you actually work, and built to last decades rather than years.
We've built bespoke garden offices across Surrey — in Weybridge, Cobham, Esher, Guildford, Epsom, Godalming, and beyond. Every project starts with a free site visit: we come to you, understand the plot constraints and your working requirements, and return with a detailed design proposal including elevation drawings. There are no vague estimates at any stage — you receive a fixed-price itemised quote before committing to anything.
The structural system is SIPs throughout — Structural Insulated Panels deliver far better thermal performance than timber frame, keeping your office warm in January and cool in July without over-relying on heating or air conditioning. Acoustic performance is a natural benefit too: SIPs walls attenuate sound significantly, which matters when you're spending the day on calls or working in a client-facing space.
Bespoke garden offices start from £20,000 inc VAT. Unlike companies who quote per square metre with a long list of exclusions, our quotes are itemised line by line — structure, cladding, glazing, electrics, flooring, plastering, site preparation and clean-up all included. You know exactly what you're getting before you sign anything.

Frequently Asked Questions
More questions? See our full FAQ →
How much does a bespoke garden office cost?
Bespoke garden offices start from around £20,000 inc VAT. Most custom home office builds sit between £22,000 and £45,000 depending on size, glazing specification, cladding choice and internal finish. Because every project is designed from scratch, we quote each one individually after the free site visit — you receive a precise, itemised quote before committing to anything.
Do I need planning permission for a bespoke garden office?
Most garden offices fall under Permitted Development, including most bespoke builds. The key rules are: single storey, maximum eaves height of 2.5m, no closer than 2m to the boundary if over 2.5m tall, and the footprint must not cover more than 50% of the garden. L-shaped or larger footprints may require a formal application. We assess every project at the design consultation and advise you clearly before you proceed. See our planning guide for the full criteria.
What makes a bespoke garden office different from a standard one?
Our standard garden offices use fixed proportions with a curated set of options — ideal for most plots and most requirements. A bespoke garden office starts from a blank page: any shape, any footprint, any combination of glazing and materials. If your garden has an unusual shape, a level change, a planning constraint, or you want a very specific layout — bespoke is the right choice.
Can you run mains power to a bespoke garden office?
Yes — and it's included as standard. Every build comes with a mains-connected consumer unit, full electrical installation, and a signed electrical certificate. We include double sockets throughout, USB charging points, and external lighting. If you need something specific — a dedicated circuit for equipment, Cat6 data cabling, a server cabinet, or additional data points — tell us at the design stage.
How long does it take to build a bespoke garden office?
From first contact to handover, allow 10–16 weeks. The design and quotation phase typically takes 2–4 weeks, materials lead time is 4–6 weeks, and the on-site build takes 2–3 weeks. We'll give you a clear timeline at the quotation stage with a fixed installation date.
Can the garden office double as a meeting room or client space?
Absolutely — and this is one of the most common requests for bespoke builds. We can design the layout around a meeting table, add acoustic wall treatment for call quality, include a kitchenette or refreshment area, and choose a cladding and glazing specification that creates the right first impression. Many of our bespoke office customers use their build for client meetings as much as solo work.
What Makes Us Stand Out
Every Green Rooms build uses the same premium specification — regardless of price point.
