Garden Room Companies Offering the Best Value
Which garden-room companies give you the most for your money? We compare published prices, installation and what’s actually included — because the cheapest advertised room isn’t necessarily the cheapest finished project.
Our current view
We therefore look beyond the headline price. Foundations, installation, insulation, electrics, flooring and finishing can materially change the true cost of a garden room.
| Company | Published starting price | Our value category | Important point |
|---|---|---|---|
| Eurocell | From £8,499 | Lower-cost installed option | Fully installed Studio Select available, but published price excludes groundworks. |
| Green Retreats | From £9,485 | Range & established national supplier | Professional installation and 12-year guarantee; specification varies by range. |
| Cabin Master | From £12,500 | Inclusive mid-market package | Base/foundations, build, insulation, internal electrics, flooring and painting included. |

Our best-value picks by buyer type
Eurocell Studio Select
From £8,499Eurocell is interesting for buyers trying to keep the initial cost of a professionally installed garden room down. Its Studio Select range currently starts at £8,499 and is described as fully insulated for year-round use.
The compact 2.44m × 2.44m model includes French doors and a full-height side window, with larger sizes available.

From £12,500Cabin Master’s starting price is higher than the cheapest options in this comparison, but the included specification is why it deserves attention.

We’re not simply ranking companies from cheapest to most expensive. For GardenSpacewise, value means considering the finished usable room.
Completed cost
What will you actually spend before the room is ready to use rather than merely delivered?
Foundations
A low headline price can become much less attractive when significant groundworks are added later.
Insulation
Year-round buyers need to understand the wall, roof and floor specification rather than accepting “fully insulated” at face value.
Installation
Supply-only, basic assembly and a complete professional installation are not equivalent products.
Internal finish
Flooring, walls, painting and heating can represent meaningful additional expenditure.
Guarantee & support
A garden room is a substantial purchase, so warranty length, scope and after-sales support matter.
The questions we’d ask every supplier
- Does the quoted price include VAT?
- Is delivery to my postcode included?
- Is a site survey included?
- Who provides the foundations or base?
- Are groundworks included in the advertised price?
- Is complete installation included?
- What is the wall, floor and roof construction?
- What insulation is used?
- What glazing specification is standard?
- Are internal sockets and lighting included?
- Is the final electrical connection from the house included?
- Is flooring included?
- Is heating included?
- Are the internal walls completely finished?
- Could access to my garden create additional charges?
- What exactly does the guarantee cover?
Ask for the ready-to-use price.
The easiest way to compare companies is to ask what the total project will cost before the room is genuinely ready for the purpose you intend to use it for.Why the cheapest garden room can cost more
Imagine Supplier A advertises a garden room for £9,000 while Supplier B quotes £13,000. Supplier A initially appears substantially cheaper.
But if Supplier A’s price excludes foundations, electrical work, flooring and internal finishing while Supplier B includes most of those items, the comparison changes completely.
This is why our Garden Room Cost Guide focuses on completed project cost rather than headline price.
Which company should you choose?

Prices and included specifications on this page are taken from the suppliers’ own published information. We check supplier information periodically, but prices and specifications can change between updates.
Supplier information checked August 2026. We recommend obtaining a current written quotation directly from the supplier before making a purchase decision.
Best value isn’t necessarily the lowest price.
Compare the building, foundations, installation and finishing as one project. That’s the figure that tells you what you’re really getting for your money.
