Arden & Oak — serving Devon
Garden Rooms in Devon.
Create the perfect space to work, relax, train or entertain with a fully insulated garden room from Arden & Oak. We design, manufacture and install premium garden rooms throughout Devon — helping homeowners create beautiful spaces without the cost and disruption of moving house or building an extension.
Local context
Designed and installed across Devon.
Devon offers some of the most beautiful homes and gardens in the UK, making it the perfect place to invest in a high-quality garden room. Our buildings are designed to complement everything from modern homes in Exeter to coastal properties in Torbay and rural homes across Dartmoor and the South Hams.
Every Arden & Oak garden room is manufactured using highly insulated SIP construction and installed on low-impact ground screw foundations. The result is a warm, energy-efficient building you can enjoy throughout the year — whether that's a garden office in Exeter, a home gym in Plymouth, a golf simulator in Torquay or a garden studio in North Devon.
Many Devon homeowners come to us looking for extra living space without the cost of moving home. A garden room delivers a dedicated workspace, a home business premises, a hobby room, a guest retreat or a fitness space — typically faster, less disruptive and more cost-effective than a traditional extension.

SIP construction
Built like a house. Insulated better than one.
Every Arden & Oak garden room in Devon 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

What people build
Popular garden room uses in Devon.
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.

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.
Planning permission
Planning permission in Devon.
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.
Devon pricing
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 £10,495.

Construction comparison
Why SIP construction outperforms timber framing.
A garden room in Devon that’s still warm, tight and level in twenty years’ time isn’t about specification — it’s about how it was built.
Traditional timber framing
- Hundreds of individual timber components
- Built entirely on site
- Numerous thermal bridges
- Greater potential for movement
- Variable workmanship
- More difficult to achieve airtightness
Arden & Oak SIP construction
- Factory-engineered structural panels
- Precision manufactured off-site
- Continuous insulation
- Exceptional structural rigidity
- Consistent factory quality
- Continuous airtight envelope
- 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
Ground screw foundations
No concrete. No mess. No waiting.
Every Devon 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.

Local FAQs
Common questions from Devon customers.
Do you build garden rooms in Devon?
Yes — Devon is part of our active service area. We design, manufacture and install across Devon from our Paignton studio. Discovery visits are free, with most consultations booked within 48–72 hours of enquiry.
Will I need planning permission in Devon?
Most Arden & Oak garden rooms in Devon 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 Devon 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 Devon 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 Devon 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.
