Garden Rooms in the East of England.
The East of England mixes some of the country's busiest commuter towns with its most open countryside. Cambridge and Chelmsford households want a quiet office away from the kitchen table; Norfolk and Suffolk clients often have the space for a larger studio, a guest room or a gym looking out over the garden. We design, build and install insulated timber-frame garden rooms across the whole region.
Designed and installed across the East of England.
Big skies and exposed sites mean wind and driving rain matter here, especially on the Norfolk and Suffolk coast. Every room is built with a sealed vapour-control layer, a warranted EPDM roof and cladding that weathers well, and the walls and roof are fully insulated for year-round use.
Much of the region sits on clay or soft ground, which is why we use steel ground-screw foundations as standard — no concrete slab, fast to install and kind to the garden. Most rooms fall inside permitted development; in conservation villages and on listed properties we handle the planning conversation as part of the design.
Why the East of England 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.
- Timber-frame engineered construction
C16 timber frame, PIR insulation, OSB sheathing and a ventilated cavity — a 209.5 mm insulated wall build-up.
- Year-round comfort
Continuous PIR insulation and an airtight envelope hold heat in February and stay cool in August.
- Precision manufactured
Every panel is CNC-cut off-site, inspected before it leaves the factory, and installed to the millimetre.
- Installed by experts
Our own crew — never sub-contracted. Same team designs, manufactures and installs. One point of accountability.
- 10-year structural warranty
Backed by panel manufacturer cover, our installation guarantee and honoured anywhere on the UK mainland.
- Designed to last
Engineered components reduce movement, shrinkage and long-term maintenance. Built to be around in twenty years.
Built like a house. Insulated better than one.
Every Arden & Oak garden room in the East of England uses Structural Insulated Panels (insulated timber-frame builds). 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

Photographers, painters, makers — high ceilings, north-light glazing options on request.
Planning permission in the East of England.
The good news: most garden rooms are permitted development and do not require a full planning application — provided the building sits within the rules for outbuildings on residential land.
- Height — typically capped at 2.5 m within 2 m of a boundary; more if further away.
- Position — the building cannot be in front of the principal elevation of your home.
- Listed buildings & conservation areas — extra restrictions apply. We handle the paperwork with you.
- Not for sleeping accommodation — annexes need separate consent, and we’ll advise before you commit.
Garden room prices.
Every Arden & Oak building is designed around your plot, so no two quotes look identical. The final price is shaped by four decisions:
- Size
- Footprint drives cost more than any other single factor.
- Specification
- Standard, Studio or Signature interior finish.
- Glazing
- Sliders, corners and roof-lights all move the number.
- Cladding
- Cedar, Thermowood, Accoya or charred timber options.
Use the instant price tool to see a firm number in under a minute — or browse the Arden Edition standard range for fully-installed pricing from £8,495.

Will I need planning permission in the East of England?
