A garden office designed around your garden, not a catalogue

Most companies sell fixed-size garden rooms and expect your garden to fit. We work the other way round: every room starts with a visit to your plot, and the design follows its shape, slope, access and light.

We have personally designed and built more than 120 bespoke garden offices across Greater London, from compact single-desk studios in Brixton terraces to multi-desk offices in Bromley and Croydon. Whether it's a quiet garden office, a soundproofed studio or a garden gym, the build standard is the same: OSB3 structural panels, 75mm or 100mm Super Therm EPS insulation, and cladding chosen to suit your house and garden.

Because most garden offices fall under permitted development, many clients go from first conversation to a finished, insulated room in 8-10 weeks, without the cost, disruption or planning risk of an extension. You deal with the same small team directly throughout, from first enquiry to the two-year aftercare visits, which is why so many new projects come from neighbours and referrals.

The bigger picture

Why more Londoners are choosing a garden office over an extension

A house extension or loft conversion can take six months or more once you include planning, party wall agreements with neighbours, and the disruption of living through a building site. A bespoke garden office avoids most of that: it's built largely off the back of your existing walls, it rarely needs a full planning application, and your home stays liveable throughout. For a growing number of homeowners across London working from home two, three or five days a week, a dedicated garden office also solves a problem an extension doesn't, a proper line between "home" and "work" that a spare bedroom or kitchen table never quite manages.

6–10m²
Single-desk office

A focused, quiet room for one person.

12–18m²
Shared office or studio

Space for two desks and a small meeting corner.

Changes mid-build?

Adding a shower room or upgrading insulation is a conversation, not a change order, we design and build everything ourselves.

FAQ

Frequently asked questions

Do I need planning permission for a garden office?

Most garden offices fall under permitted development and don't need planning permission, but the rules depend on your garden, your home, and any local restrictions. We check this at the first visit, and prepare any application for you if one is needed.

I don't have side access, can you still build?

Yes. Tight or no side access is one of the most common challenges we solve for London gardens. We plan delivery and construction around narrow gates, steps and shared passageways as standard.

Will a garden office add value to my home?

A well-built, properly insulated garden room is generally seen as a valuable, usable addition to a property, without the cost or disruption of an extension. We're happy to talk through what's realistic for your house.

What if it's not insulated well enough for winter?

Every room we build uses OSB3 panels with 75mm or 100mm Super Therm EPS insulation as standard, so it stays comfortable to work or relax in through a London winter, not just a fair-weather shed.
