Garden Building Supplier Perth in Perth & PerthshireBespoke Garden Rooms, Offices, Studios & Outbuildings

Marshall & Co are a specialist garden building supplier based in Perth, designing, manufacturing and installing bespoke garden rooms, garden offices, studios, gyms and storage outbuildings across Perth, Dundee and the wider Perthshire region. Unlike kit-shed retailers, every garden building we supply is built specifically for your garden, your purpose and your budget — fully insulated, fully wired, fully finished and ready to use year-round.

Demand for high-quality garden buildings in Perthshire has grown enormously since 2020. Whether you need a quiet home office away from the house, a teenage retreat, a hobby studio, a yoga and pilates room, a home gym, a garden bar or a guest annexe, a bespoke garden building gives you the space without the cost or disruption of a house extension.

As a local garden building supplier we control the whole process — design, base preparation, frame manufacture, cladding, insulation, electrics, plumbing (where required), interior finishing and final commissioning. One company, one project manager, one programme, one set of warranties. Browse our dedicated garden room service for full specifications, and ask about combining your build with a timber or composite deck for a complete garden transformation.

As part of our established building and joinery firm in Perth, we deliver every project to a premium standard across Perth and Perthshire.

Why Marshall & Co?

There are essentially three options when you're looking for a garden building in Perthshire: a flat-pack kit from a national retailer, a modular pod from an online specialist, or a bespoke build from a local garden building supplier. Each has trade-offs.

Flat-pack kits are cheap but rarely insulated to year-round standard, often have flimsy single-skin construction, and you (or a hired carpenter) have to assemble them. They're fine for occasional summer use but disappointing as serious working or living space.

Modular pods look great in marketing photos but can feel boxy on site, are sized to standard footprints rather than your garden, and arrive on a flatbed lorry that sometimes can't access tighter Perthshire gardens. Costs are high (£25k–£60k for typical sizes) and customisation is limited.

A bespoke build from a local garden building supplier like Marshall & Co gives you the right building for your garden, your purpose and your budget. Sized to fit, designed to suit your taste (modern cedar, traditional larch, painted finish), and built on site by carpenters who can adapt to ground conditions, access constraints and tree-root issues that kit and modular options can't accommodate.

What you'll use the garden building for drives the specification. A garden office for full-time working needs serious acoustic insulation, ethernet (Wi-Fi alone won't cut it across 30m of garden), proper heating (typically a wall-mounted electric panel heater plus ceiling-cooled summer cooling), and good natural light. Typical size 12–18m².

A garden studio for art, music or yoga needs floor-to-ceiling glazing for natural light, reinforced flooring (especially for pilates/yoga reformer work or pottery wheels), and excellent ventilation. Typical size 15–25m².

A home gym needs heavy-duty engineered flooring (typically 18mm structural ply with rubber gym tiles), reinforced wall fixings for racks, robust ventilation, and often AC for summer use. Typical size 18–30m².

A garden bar or entertaining room is the most flexible spec — typically a wider front opening (bi-fold or large sliding doors), bar fit-out, integrated lighting, sound system pre-wiring and sometimes a small toilet. Typical size 15–25m².

We'll talk through your intended use during the site visit and recommend the right size, layout and specification for your needs and budget.

Bespoke garden building costs in Perth typically range from £15,000 for a basic 10m² insulated room with electrics, up to £45,000+ for a fully fitted-out 25m² garden office or studio with bi-folds, bathroom, premium finishes and integrated lighting. The average is around £22,000–£32,000 for a mid-sized garden room with quality cedar cladding, double-glazed bi-folds and full electrical fit-out.

Lead time from order to completion is typically 8–14 weeks. Construction itself takes 4–8 weeks on site depending on size, weather and access. Most garden buildings under 4m height to ridge and 30m² floor area fall under permitted development in Scotland, so no planning permission is required — but we always check the specifics for your site.

All quotations are fixed-price after the site visit and design agreement. There are no hidden extras for foundations, electrics, finishes or rubble removal — everything is included in the headline price.

Three reasons Perthshire homeowners choose us over national garden room brands: design flexibility, build quality and aftercare. Design flexibility means your building isn't constrained to off-the-shelf footprints — we'll design something that fits your specific garden, taste and budget. Build quality means proper structural timber framing, full PIR insulation (not loft-roll), EPDM or composite roofing rated for 50 years, and quality double-glazed aluminium or timber windows — not the cheap UPVC many kit suppliers use.

Aftercare means we're 5 minutes away if something needs adjusting. Many of our clients have come to us after disappointing experiences with national garden room companies who installed and disappeared. We're a local construction company — we live here, our reputation is on every garden we work in, and we provide a 12-month workmanship guarantee plus manufacturer warranties on roofing, glazing and electrics.

If you're considering a garden room, office, studio, gym or workshop, get in touch for a free site visit. We'll measure up, talk through what you want to use it for, advise on size and position, and provide a fixed-price quote within 5 working days.
