A Timber Summerhouse that is made to last! The world’s most adaptable summerhouse ,the Power 6’x4′ Tongue and Groove Timber Summerhouse can be installed how you want by allowing you to place the door and windows in any position.

The door can be placed in any position on any side, which you can choose as you’re assembling the building. This is a premium quality summerhouse with high grade timber sourced from the finest Scandinavian forests. It is tongue and groove throughout giving you a garden shed which will last for many years.

Made from 12mm Scandinavian timber with 44x28mm Timber Framing rounded at each corner to give a stunning finish. The panels are screwed together and so when joined it creates double strength 44x56mm thick framing. Also comes with a 10 year guarantee against timber rot, decay or insect infestation.

The windows are made from toughened safety glass. The glass is already internally beaded so you don’t need to fit the glass yourself and PVC sills complete the window units to stop water ingress and provide a stunning finish.

ROBUST– All of Power’s wooden buildings have high-grade premium quality Scandinavian tongue and groove timber throughout including roof and floor – No chipboard or OSB.

RESPONSIBILY SOURCED TIMBER – Power’s summerhouses use 12mm extra thick shiplap cladding responsibly sourced in line with their sustainability policy.

MODULAR DESIGNED– Modular panels allow you to position the door and windows of your garden summerhouse in any position as you build it. Full fixings and instructions are included with easy-to-manage panels that easily fit through your house.

Shed Base Preparation

You will need a firm and level base for the shed to go on. The shed comes with a T&G floor with floor joists on the underside to lift the building off the ground, but you will still need something firm and level for it to go on. This can be concrete, paving slabs, timber bearers or any other suitable firm and level base. If you have any questions on bases then please get in touch. Some silicone around the windows on the outside would also be beneficial.

The base is slightly smaller than the external measurement of the building, i.e. the cladding should overhang the base, creating a run for water. It is recommended that the floor is at least 25mm above the surrounding ground level to avoid flooding.

If you have not chosen to purchase our Power Base then other suitable bases would include a concrete base or a paving slab base (slabs laid on top of 50mm of sharp sand).

Optional Timber Base (chargeable)

This base is made from 90x50mm pressure treated timber bearers. It is a kit which requires self assembly but comes with the instructions and fixings required to screw it together.

Each base section matches each floor panel perfectly to make assembly easy.



The shed will arrive on a pallet delivered by our trusted courier. It will be delivered on an 18ton vehicle and a tail lift / pallet truck will unload the pallet. If there are any access problems for an 18ton vehicle (similar to the size of a bin wagon) then please advise us when placing the order so we are able to make alternative arrangements.
