The greenhouse parts plus glass arrived safely packed.
We erected the greenhouse ourselves and after a couple of initial errors we got into the swing of it and are really pleased with the results.
The diagrams in the instruction manual could be clearer but we got there, though it did seem to take many hours.

It was easy to choose the greenhouse itself and then the extras. Hassle free and it was delivered when expected. I would however advise that you may want to hire someone to put it together for you, unless you are good at following this sort of instructions. The greenhouse looks fantastic and I am very happy to have bought it. I would recommend the Greenhouse Stores.

Brilliant service from start to finish and a slight issue with my order was resolved extremely quickly great service

Great product and straight forward to assemble, would suggest a few addition 3D views in the assembly manual but thats only so you can confirm which orientation you are working on. Also make sure the base is securely fixed prior to the build and ensure you are within 1mm on corner to corner measuring so you know you are square before you start building up. Some of confusion on some of the instructions as the description can be read several ways. All in all a very simple build. Only concern is how it acts in strong winds, I have positioned mine adjacent to a fence on one side and a structure at the rear to try and reduce the potential for wind causing damage

From ordering to delivery went fine had a phone call to let me know when delivery was coming. And it was on time.
Verified Customer
Was waiting for over a week for delivery from order date but apparently this is the norm with this company so be aware if you want it quick - delivered well boxed- no damage- no parts missing - husband assembled by himself and found it easy - couldn't find a small compact one like this on other websites and if available on other sites no shelves available which we feel you need - overall very pleased with purchasing method and product - enclosed pictures so other customers can gauge storage

Greenhouse Stores were the answer to my prayers. Amazing people who went above and beyond to satisfy my requirments and to ensure that I was happy with everything from ordering to having the Greenhouse put up. Top class from start to finish and wouldnt ever go anywhere else.
About our potting sheds
We stock Swallow potting sheds exclusively - the only ThermoWood potting shed range manufactured in the UK. Prices start from £3,307 for the Swallow Jay (6ft wide) and £3,485 for the Swallow Rook (8ft wide). Free UK delivery and professional installation are included in every price shown.
Each potting shed combines a glazed front for growing with solid timber walls for insulated storage. Standard features include toughened safety glass, automatic roof vents, a solid timber floor, and full-length slatted staging. Painted finishes are available on both ranges. For practical layout ideas, see our potting shed layout guide.
Why We Chose This Range
"We exclusively stock Swallow potting sheds for one simple reason: ThermoWood. Standard timber sheds shift and warp in the damp UK climate, causing glass to crack and doors to jam. Swallow heats their timber to 215°C, effectively 'cooking' the moisture and resin out. It means the frame stays dead straight, the locks always align, and you don't need to paint it every year."
- Matt, Founder of Greenhouse StoresSwallow jay vs rook: which potting shed size?
We stock two ranges to suit different garden widths. The Jay fits narrower spaces; the Rook gives workshop-level room.
| Feature | Swallow Jay (6ft Wide) | Swallow Rook (8ft Wide) |
|---|---|---|
| Width | 6ft 8" (2,035 mm) | 8ft 9" (2,660 mm) |
| Lengths Available | 6ft to 20ft | 6ft to 20ft |
| ThermoWood From | £3,307 | £3,485 |
| Painted From | £5,093 | £4,239 |
| Door | Single half-glass with mortise lock | Single or double doors on larger sizes |
| Staging | Full-length slatted bench (one side) | Full-length bench + wider aisle |
| Best For | Small to medium gardens, propagation | Larger gardens, workshop use |
| Matt's Pick | Swallow Jay 6x8 - the best balance of growing space and storage for most UK gardens. The 8ft length gives you a full potting bench plus room for overwintering plants. | |
Potting shed vs greenhouse: which should you buy?
When we install potting sheds, customers often tell us they nearly bought a greenhouse instead. Both are glazed garden buildings, but they serve different jobs. A potting shed gives you a warm, secure workspace all year round. A greenhouse gives you maximum light for summer cropping.
| Feature | Potting Shed | Greenhouse |
|---|---|---|
| Light | Glazed front and partial roof | Fully glazed on all sides and roof |
| Insulation | Solid timber walls retain heat | Glass loses heat rapidly in winter |
| Storage | Built-in shelving, lockable door | Open staging only, no secure storage |
| Security | Mortise lock, solid timber walls | Glass panels, basic catch locks |
| Year-Round Use | Comfortable spring to late autumn | Needs heating below 5°C |
| Best For | Seed starting, overwintering, tools | Tomatoes, peppers, summer crops |
If you want maximum growing light for summer crops, browse our greenhouse collection. If you want one building that handles propagation, potting, and secure storage across all seasons, a potting shed is the better investment. Still deciding? Read our detailed potting shed vs greenhouse comparison.
Types of potting sheds we offer

Our most popular potting shed for urban gardens. 6ft 8" wide with lengths from 6ft to 20ft. Natural ThermoWood finish requires no painting. Includes toughened glass, auto-vents, slatted staging, and a solid timber floor. Single half-glass door with mortise lock. From £3,307 with free installation.

Swallow Rook ThermoWood
The wider 8ft 9" body gives workshop-level space. Wide aisles, room for a chair and heater, and generous storage on the non-glazed side. Double doors available on larger sizes. From £3,485 with free installation.
Swallow Rook Painted
The full-size Rook with a premium factory-applied painted finish. All the space of the ThermoWood Rook with a colour of your choice. Popular with customers who want the potting shed to complement a painted fence or garden room. From £4,239 with free installation.
Matt's Installation Tip: The "Breathing Space"
These potting sheds include a solid timber floor. Never lay them directly onto grass or soil. The floor needs airflow underneath.
We recommend a base of concrete or paving slabs matching the shed's footprint exactly. Use pressure-treated timber bearers to lift the floor 50 mm off the slabs. This allows air to circulate underneath and prevents rising damp, adding years to the building's life.
All Swallow potting sheds are manufactured to order. Lead times are typically 4-8 weeks depending on season. You pay a 20% deposit at checkout and the remainder after installation. Our professional fitting team assembles the building on site, usually within a single day.
Every model includes automatic roof vents, toughened safety glass, and full-length staging. Browse our potting benches for additional workspace, or explore our combined greenhouse shed combis for a dedicated growing section alongside enclosed storage.

Frequently Asked Questions
-
How much do potting sheds cost?
Swallow ThermoWood potting sheds start from £3,307. The wider Swallow Rook (8ft) starts from £3,485. Painted finishes add roughly 25-30% to the ThermoWood price. All prices include free UK mainland delivery and professional installation. You pay a 20% deposit at checkout and the balance after the build is complete.
-
What is the best potting shed to buy in the UK?
The Swallow Jay 6x8 ThermoWood is our best-selling potting shed. It fits most UK gardens, gives you a full-length staging bench plus storage shelving, and the ThermoWood frame lasts 25-30 years without annual treatment. For larger gardens or allotments, the Swallow Rook 8x10 gives genuine workshop-level room. Both include free professional installation and a 12-year manufacturer's warranty.
-
Do I need planning permission for a potting shed?
Most potting sheds do not need planning permission. Buildings under 2.5 m tall that cover less than 50% of your garden area are normally permitted development. Structures within 2 m of a boundary must stay below 2.5 m in height. Conservation areas and listed buildings have stricter rules. Check your local council's planning portal before ordering. See our planning permission guide for full details.
-
What base do I need for a potting shed?
A firm, level concrete or paving slab base is required. The base must match your potting shed's footprint exactly. We recommend lifting the shed 50 mm off the base using pressure-treated timber bearers for airflow underneath. A poor base causes door alignment issues and can void your warranty. See our concrete base guide for step-by-step instructions.
-
What is ThermoWood and why does it matter?
ThermoWood is timber heated to 215°C to remove moisture and resin. This changes the wood's cellular structure permanently. The result is a frame that will not warp, twist, or rot for 25-30 years. Unlike pressure-treated timber, ThermoWood needs no chemical retreatment. Apply optional wood oil every few years to maintain colour, but the structural integrity requires no ongoing treatment.
-
Are potting sheds worth the money?
A ThermoWood potting shed is a 25-30 year investment. Standard pressure-treated timber sheds develop rot after 10-15 years and need retreatment every 12-18 months. ThermoWood frames stay structurally sound with zero chemical maintenance. The toughened safety glass, mortise lock, and solid timber floor add practical value you use every week. Our customers consistently tell us they wish they had bought one sooner.
-
Can I use a potting shed for general storage?
Yes, potting sheds are designed for dual use. The glazed front half provides growing space for seedlings and tender plants. The solid rear section has shelving for tools, pots, and garden equipment. The mortise lock on the door keeps everything secure. For a dedicated storage section alongside growing space, consider a combined greenhouse shed combi.
-
How long does installation take?
Professional installation typically takes one day on site. Our fitting team handles assembly, glazing, and fitting the automatic vents. Delivery and installation happen 4-8 weeks after you confirm your base is ready. You do not need to lift a finger beyond preparing a level base.
