Garden Rooms in London.
London gardens ask one thing above all: make every square metre count. Plots are tighter, planning culture is more attentive, and neighbours are closer than in our South West counties — which is why our London builds lean toward longer, narrower, taller-glazed pavilions with discreet eaves and considered roof drainage. We design and install across all four quadrants of the city, with a planned-route install crew working week-on, week-off between the South West and the capital.
Designed and installed across London.
We deliver throughout the M25 — from the Hampstead and Highgate villas of the north to the Wimbledon Common gardens of the south west, the Dulwich Village conservation lanes of the south east and the Chiswick and Kew riverside terraces of the west. Most London installs need careful logistics — restricted parking, side-access constraints, sometimes a hand-carry route through the house — and we plan that into the survey from day one.
Permitted development is the default starting point for most London garden rooms (under 4 m to the eaves where boundaries allow), but we treat conservation area, Listed-property curtilage and Article 4 direction work as the standard rather than the exception in the capital.
Why London clients choose Arden & Oak.
We’re a small, architecturally-led UK studio. We don’t subcontract, we don’t volume-build, and we don’t sell finance. What we do is design and install premium, year-round garden rooms that earn their place in your garden.
- 10-year structural warranty
Backed by SIP manufacturer cover and our own installation guarantee.
- Architectural, not catalogue
Every drawing is for your plot, your aspect, your sightlines — not a brochure size.
- Our crew, never sub-contracted
Same team designs, manufactures and installs. Single point of accountability.
- 6–8 week typical lead time
From signed quote to handover. SIP off-site manufacture means weather doesn't stop us.
Popular garden room uses in London.
The brief varies — a Clifton home office, a Plymouth music studio, an Exeter therapy room, a Truro yoga retreat. The architecture adapts. These are the most common briefs we see in the South West.
- Garden offices
A separate, year-round workspace with proper acoustic separation and UK building-reg-grade insulation.
- Home gyms
Reinforced flooring, mirrored walls, dedicated power and ventilation — designed around the equipment.
- Golf simulator rooms
Year-round practice — ceiling heights, projector mounts and floor build-up specified for trackman or SkyTrak.
- Garden bars
Entertain in a stylish, weatherproof retreat — bar back, integrated lighting and bifold openings as standard.
- Yoga & wellness studios
Generous glazing, polished or engineered timber floor, calm palette — designed for movement and stillness.
- Therapy & treatment rooms
Quiet, private, professional. Often used by counsellors, beauty therapists and personal trainers.
- Music & recording studios
Acoustic insulation upgrades available — vocal rooms, podcasting and home studios.
- Creative studios
Photographers, painters, makers — high ceilings, north-light glazing options on request.
Built like a house. Insulated better than one.
Every Arden & Oak garden room in London uses Structural Insulated Panels (SIPs). It’s the construction method chosen by Passivhaus architects for a reason: factory-precision tolerances, continuous insulation and zero cold bridges.
Full specification →- U-value 0.17 W/m²K — better than UK building regs
- Manufactured indoors in a controlled environment
- No structural cold bridges through the build-up
- Outer skin can be cedar, Thermowood, Accoya or charred
- Vapour-controlled inner layer — no condensation risk
- Installed in a single day with zero excavation spoil
- No concrete cure time — build starts immediately
- Reversible — leaves the garden almost untouched if removed
- Suitable for sloping plots and clay-heavy ground
- Engineered for the building's load case, not estimated
No concrete. No mess. No waiting.
Every London install starts with engineered ground screws — the same technology used for telecom masts and architectural glass houses. Installed in a single day, with no excavation spoil and no concrete cure time.

Common questions from London customers.
Do you build garden rooms in London?
Yes — London is part of our active service area. We design, manufacture and install across London from our Paignton studio. Discovery visits are free, with most consultations booked within 48–72 hours of enquiry.
Will I need planning permission in London?
Most Arden & Oak garden rooms in London fall within Permitted Development Rights — height kept below 2.5 m at the eaves, set back at least 2 m from boundaries, and under 50% of the original garden footprint. We confirm this in writing as part of the consultation, and handle full applications where listed status, AONB or conservation-area rules apply.
How long does a London installation take?
From signed quote to handover, the typical lead time is 6–8 weeks. Ground screws install in a day. SIP factory production takes around three weeks. Site assembly, glazing, electrics, cladding and finish take a further 5–10 working days depending on size.
What's the starting price for a London garden room?
Our entry studio (The Snug) starts at £11,995 fully installed. A typical mid-spec garden office or gym lands between £18,000 and £32,000. See the full pricing breakdown for what's included — or explore the funding guide for the common ways customers pay for their build.
Are foundations included in the London quote?
Yes. Ground screw foundations are included as standard on every fixed-price quote. There are no surprise extras for typical UK garden ground conditions — we survey first.
