Overview
This 20′ x 10′ Forest 4Life apex shed is a large, windowless storage building built from pressure treated overlap timber, carrying a 25 year guarantee against rot. The windowless design leaves maximum wall space free for shelving and heavy-duty storage.
For a slightly smaller windowless apex model in the same range, see the 15×10 Forest 4Life Windowless Double Door Apex Shed.
Key Features
- 20′ x 10′ (5.96m x 3.21m) large windowless apex shed
- Pressure treated overlap cladding
- 25 year guarantee against rot
- Maximum wall space for shelving
- Double doors for wide access
Roof Types
The apex roof rises to a central ridge, giving strong headroom across a shed of this scale and shedding rain efficiently from both sides. That extra height makes it much easier to store tall items and move around freely inside.
Dimensions
- Overall width: 20′ (5.96m)
- Overall depth: 10′ (3.21m)
- Roof style: apex
- Windows: none fitted
Construction
Overlap boards are fixed horizontally along a robust timber frame built for a structure of this size, each board overlapping the one below to shed rainwater effectively. Pressure treatment forces preservative into the timber during manufacture, supporting the long guarantee period.
Treatment & Guarantee
The 25 year guarantee against rot reflects the pressure treatment used throughout this shed. We still recommend checking cut edges and joints occasionally, touching these up with a compatible preservative if needed.
Doors & Windows
Wide double doors make it easy to move mowers, bikes and bulky items in and out, and the windowless walls leave maximum space for shelving and fixed storage. A mid-size windowless apex option in the same range is the 12×8 Forest 4Life Windowless Double Door Apex Shed.
Assembly Information
Given the size of this shed, assembly is best tackled by two or more people over a full weekend, following the supplied instructions carefully and allowing extra time for a build of this scale.
Delivery Information
Delivery is by pallet carrier to the nearest accessible point at your property. Please arrange help to move the panels into the garden, as the driver delivers to kerbside only.
Optional Upgrades
Additional shelving or a floor upgrade may be available for this model. Contact our sales team before ordering to check current options for a shed of this size, particularly if you plan to fit workbenches.
Frequently Asked Questions
Why choose windowless over windowed?
A windowless design frees up the maximum amount of wall space for shelving, workbenches or fixed storage racking along every wall.

It covers the pressure treated timber against rot when the shed is maintained as recommended; full terms are available on request.
What base is recommended?
