The BillyOh Penton Summerhouse with Side Store combines two types of garden buildings into one fantastic product; A stylish Summerhouse and a Garden Storage unit. With the Penton, you have a summerhouse in which you can relax and enjoy some quality time with your loved ones, and a storage unit that is ideal for storing away all of your garden essentials.

If you want to have a summerhouse and a storage shed but garden space does not allow then this great 2in1 building could be the solution to your problem and provide you with both in one unit.

Modern, Stylish Design

The Penton has been designed to be a stylish and modern addition to any garden. With tall Styrene glazed windows and wide-opening double doors, you can relax inside of your summerhouse and admire your garden all year round.

For added convenience and mobility, the Penton has been designed with a high roof which makes mobility inside extremely easy.

Strong T&G Construction

Strong T&G Construction

Incorporated into the Penton Summerhouse design, is our incredibly popular Tongue and Groove construction. The T&G wooden boards give the corner summer house a classic, authentic, smooth look, perfect for more traditionally styled gardens.

The panels are 11mm thick and interlock together, giving the outdoor garden unit it’s incredible strength. The construction denies any water entry, giving valuable protection against the elements, with the joints well protected against long term issues. With its strong T&G construction, the Penton Summerhouse has a reliable structure which can withstand the harsh weather and be a feature of your garden for years to come.

11mm T&G Roof Included

Included with the Penton Summerhouse is an 11mm Tongue & Groove Roof. The heavy duty roof is extremely durable and will not become damaged by harsh weather or falling debris, providing your summerhouse with a strong and reliable covering.

For increased protection, Green Mineral Roofing Felt is available as an additional extra. Roofing felt provides the roof with a waterproof covering, protecting it from weather and increasing the lifespan.

Pressure Treated Option Available

Pressure Treated Option Available

The Penton is available as a Pressure Treated Option. Pressure Treatment gives the timber added strength and protection, making it better able to withstand wear and increasing the lifespan. Pressure treated wood does not require annual treatment to keep it protected, so it is a great option for those who want a lower maintenance building after installation.

All of our non-pressure treated buildings are Factory Treated for Transit, but require treatment once installed for protection. We have a range of paints and primers available as additional extras with the Picton. Available in a range of colours, you can personalise your building to you and ensure it compliments your garden perfectly. Note: All paints are supplied as a tin, not applied prior to delivery.
