Garden Rooms with Storage We've Built
The Secret Door
Our signature detail — a storage access door clad in the same material as the surrounding wall. From the outside it looks like a seamless panel. Push it and it opens to a full storage room behind.
It solves the perennial problem of garden storage without the eyesore of a separate shed, and without using up more garden space. One structure, two purposes.
What Goes in the Storage Area?
The storage section is weatherproof, electrified, and secure — not just a bare cupboard.
Bikes & E-bikes
Full-height clearance and enough depth for 2–3 bikes stored side by side.
Garden Tools & Mower
A petrol or electric mower, strimmer, leaf blower and all associated tools.
Seasonal & Sports Kit
Skis, golf clubs, camping gear, outdoor furniture covers — bulky items sorted.
1–1.5m
Typical depth
Light + socket
Electrics included
Weatherproof
Same SIPs structure
Permitted Development Applies to the Whole Structure
The storage section doesn't change the planning position — the same Permitted Development rules apply to the combined structure as to any garden room. Most builds don't require planning permission.
We confirm this at the free site visit. If you're on a listed building, in a conservation area, or on a corner plot with boundary considerations, we'll tell you clearly what applies before you commit to anything.

"I've got a home office AND storage shed in one beautiful space. The quality of the build is excellent and James was great to work with from start to finish. Really happy with the end result."
"Brilliant space that now serves as both a garden office and a storage room. Very efficiently designed and excellent quality materials throughout. I would recommend The Green Rooms to anyone considering this type of project."

Frequently Asked Questions
More questions? See our full FAQ →
How big is the storage area?
The storage section is typically 1–1.5m deep across the full width of the structure — giving you a generous area that comfortably fits bikes, a lawnmower, garden tools, outdoor furniture, and seasonal storage. The exact depth is agreed at the design stage based on your overall room width and how you plan to use the space.
Does the storage area have electrics?
Yes — the storage section is on the same electrical installation as the main room. A light fitting and a socket are included in the storage area as standard, so you can actually see what you're doing and charge power tools. The consumer unit serves both areas.
What can be stored in the storage area?
The storage section is fully weatherproof and secure — it's part of the same SIPs structure as the room. Common uses include: bikes and e-bikes, lawnmower, garden power tools, outdoor furniture covers, ski gear and winter sports equipment, golf clubs, seasonal decorations and general overflow. Because it's enclosed within the main structure, it's more secure and weatherproof than any standalone shed.
How does this compare to having a garden room and a separate shed?
Two separate structures costs more, takes up more garden space, and looks less cohesive. The garden room with storage solves both needs in a single footprint, with a seamlessly clad secret door that blends into the exterior. One planning permission consideration, one installation, one neat finish. If you'd like to explore the option, see our standard Garden Room for comparison.
Does a garden room with storage need planning permission?
The same Permitted Development rules apply as to any garden room — most builds don't require planning permission. The storage section doesn't change the planning position, as it's part of the same single-storey structure. We confirm your position at the free site visit. See our getting started guide for the full Permitted Development criteria.
What is the minimum garden size needed for a garden room with storage?
As a guide, a 4×3m build (including storage) fits comfortably in most medium-sized Surrey gardens. The 50% garden coverage rule under Permitted Development applies — so we'll check that the footprint stays within permitted limits. At the free site visit we bring a tape measure and give you a clear picture of what fits and what options look best in your space.
What Makes Us Stand Out
Every Green Rooms build uses the same premium specification — regardless of price point.

20-Year Roof Guarantee
