Arden & Oak — serving Ashburton
Premium Garden Rooms in Ashburton.
Ashburton sits on the Dartmoor National Park edge — larger plots on the town's fringe, a design-conscious independent client base, and briefs that mix creative studios with straightforward home-office builds. National Park volume rules apply on plots inside the boundary.
Local context
Drawn for Ashburton. Built by us.
Charred cedar and thermo-treated ash cladding sit well against the Moor's stone-and-slate palette. Ground screws handle the mixed ground. We handle the National Park design guidance and pre-application enquiries where a plot needs one.
Why us
Why Ashburton 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.

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

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