Description

The 6 x 6 Powersheds Corner Summerhouse combines timeless craftsmanship with a clever, space-saving design. Its unique five-sided pentagon shape is made to sit snugly in any garden corner, transforming an underused area into a beautiful and practical retreat. Crafted from high-grade Scandinavian tongue and groove timber throughout – including the floor and roof – it offers exceptional strength, a refined appearance, and year-round durability. Every panel is treated with a special formula enhanced preserver for added weather protection.

Attention to detail is evident in every feature. The well-braced door, complete with a press lock and key, is matched with galvanised ironmongery to guard against rust. Toughened safety glass, 500% more resistant to heat and shock than standard glass, ensures both safety and clarity, while PVC sills provide extra protection against moisture. These features are not usually seen on summerhouses, making this an exceptional choice. Superior rounded framing, internal corner bracing, and extra headroom create a structure that feels as sturdy as it is spacious. Simple to put up. Tough to knock down.

The finishing touches make this summerhouse stand out. A high-performance polyester felt roof offers tear-proof, water-resistant protection that surpasses standard roofing materials, keeping the interior dry and inviting. Its tall glazing invites natural light to flood the space, making it perfect for relaxation, creativity, or simply enjoying the view of your garden in comfort. With a 10-year guarantee against timber rot, decay, or insect infestation – and a lifespan you can expect to reach 25 years – it’s an investment in lasting quality.

Optional Summerhouse Base

A solid base sets your shed up for a lifetime of use. Our optional summerhouse base kit is crafted from UC4 pressure-treated 95x44mm timber bearers and tailored to fit your Powershed perfectly. Designed for straightforward self-assembly, each base section aligns precisely with the summerhouse’s floor panels, and it includes all fixings and clear instructions.

Optional EPDM Rubber Roof

Enhance the durability and weather resistance of your summerhouse with our high-quality optional EPDM roofing solutions.  Designed to provide superior protection, EPDM is a versatile and long-lasting material that ensures your timber structures remain secure against the elements. Its strong waterproof properties, combined with resistance to UV rays and temperature fluctuations, make it an ideal choice for outdoor use.

Corner Summerhouse Aftercare:

The Powershed corner summerhouse is built from timbers that have been treated with an advanced wood preservative containing wax additives, giving it year-round protection. To keep the wood in top condition and looking its best, we recommend applying a fresh coat of treatment once a year. This not only preserves the high-quality finish but is also required to keep the 10-year anti-rot guarantee valid. Every summerhouse also comes with a standard 1-year manufacturer’s warranty.

FAQ:

Does my summerhouse need a base?

Yes. For your summerhouse to remain stable and weatherproof, it must sit on a firm, level surface. Concrete, paving slabs or timber bearers all work well.

For ease, we offer an optional purpose-built Summerhouse Base Kit—made to match your Powershed and make setup simple.

Can I choose where the door and windows go?

Yes, you can. Powersheds are built with adaptability in mind. During assembly, you’ll choose the exact positioning of your windows and doors (excluding 7x5 models)—there is no need to pre-select. Each summerhouse comes with full instructions and fixings for a smooth build.

Can I add an extra door?

Absolutely. Want double doors or a tunnel-through design? You can upgrade to a two-door setup. Contact us for pricing and options.

Note: Summerhouses with high-security locks may carry an additional charge for dual-door installations.
