The perfect place in which to relax and enjoy your garden, the 6 x 4 Forest 4Life Double Door Apex Summer House (1.99m x 1.23m) includes pressure-treated wood, extensive shatterproof glazing and a fabulous 25-year guarantee. Buy this beautiful garden summerhouse now and it’s sure to become one of your property’s most treasured features for decades to come.

Fully Modular Design and High-Quality Build

Thanks to a fully modular design, this small summerhouse is much easier to assemble and far stronger than most wooden summerhouses. This fully modular design also gives you a market-leading choice of door and window placements, so you can customise the summerhouse to your exact requirements.

Supported by a 28mm frame, the 7mm straight-cut, overlap cladding allows for the natural movement of the timber and ensures excellent rainwater runoff. The floor is constructed from extra-thick 14mm solid wooden boards, so will easily accommodate your heavier items and cope with regular footfall. Pressure-treated bearers allow air to circulate beneath the floor, preventing damp and rot. The 8mm OSB roof comes with a traditional apex design, diamond-shaped finials, and green felt cover to provide you with complete weatherproof protection.

Doors and Windows

You can easily access this summerhouse via glazed double doors, which are fitted with sturdy handles, a tower bolt and turn buttons. Five further large, fixed windows ensure the interior enjoys an abundance of natural light. All of the glazing is made from PET, so is lightweight and completely shatterproof.

Maintenance Free and a Market-Leading Guarantee

Constructed using FSC® certified wood, this summer house is pressure treated and suppled with a market-leading 25-year anti-rot guarantee, so further treatment is never required, saving you time and money.

White Glove Delivery

Free delivery is available to most UK addresses using Forest's White Glove Service, who will deliver the summerhouse straight into your garden, with all of its packaging removed. Fixings and instructions are included for a straightforward assembly.

Optional Upgrades

If you’d rather the professionals do the work for you, why not select our summerhouse installation service as an optional upgrade? You can purchase a pressure-treated summerhouse base as an optional extra too.

The 4Life Summerhouse Range - Overlap, Pressure Treated Summerhouses available in a range of sizes by Forest GardenThe 4Life Summerhouse Range - Overlap, Pressure Treated Summerhouses available in a range of sizes by Forest Garden
Number 1 TreatmentNumber 1 Treatment


Pressure treatment forces preservative deep inside the wood. The result is long-lasting protection against rot and fungal decay. There is no need to re-treat EVER, saving an estimated £200 in time and treatment costs compared to dip-treated summerhouses.

Number 2 FloorNumber 2 Floor


Far superior to standard summerhouses, the 14mm wooden boarded floor will withstand years of constant footfall and enables you to store heavier items. It is fitted with pressure-treated bearers too, improving air circulation underneath the summerhouse, which prevents damp and rot.

Number 3 CladdingNumber 3 Cladding


The straight-edge 7mm overlap cladding is a traditional style, which we all know and love. It is robust, durable and ensures excellent rainwater runoff. It is supported by a sturdy 28mm x 28mm frame for even greater strength and solidity.

Number 4 WindowsNumber 4 Windows


Both the glazing on the doors and the additional windows are made with PET glazing. It is a lightweight material, completely shatterproof and far safer than conventional glass.

Number 5 Wide Double DoorsNumber 5 Wide Double Doors


Wide double doors offer you comfortable access to the interior. They are fitted with ¾-length windows so the summerhouse benefits from plenty of natural light. Interior bolts and exterior turn buttons keep these doors secure, whatever the weather.

Number 6 Robust RoofNumber 6 Robust Roof


The 8mm OSB roof features a traditional apex design featuring a metal truss bracket that adds strength to the roof, and a green mineral felt cover gives you complete protection from the elements.


You'll only ever need one summerhouse with a 4Life summerhouse!



Every 4Life summer house is made in Great Britain from ethically-sourced, FSC®-certified wood, so you’re benefitting from highly-skilled workmanship, while being kind to the environment.









The Pressure treatment process for timber has been applied to products for a number of years; the key benefit of this process is that the preservative is forced under vacuum pressure right deep into the heart of the wood and the grain structure. The preservative becomes an integral part of the wood; giving a long life and protection against rot.


This process also means that you never have to apply preservatives to your garden summerhouse, and it allows the natural colours of the timber to show through and so your summerhouse blends easily within your garden. Surprisingly, our pressure treated summer houses are only slightly more expensive than dip treated alternatives.



Timber is loaded into chamber and a vacuum empties timber cells of air.



Cylinder is flooded under vacuum with preservative.



Preservative is forced deep into timber using hydraulic pressure.



Another vacuum extracts excess preservative.




Timber draws in surface excess of preservative under low pressure, then is left to dry.
