Our 12×8 Ultimate Pent Garden Room – Half Glazed not only offers you superior build and reliable durability, but it also provides you with endless possibilities for how to make the most of this garden building. Will you create the perfect summerhouse for entertaining and relaxing? Or design a tranquil garden office? Perhaps you’ll turn it into a home gym? However you use this beautiful contemporary space it is sure to be a valuable addition to your garden and lifestyle. Both stylish and functional, the summerhouse has been clad in attractive 12mm tongue and groove timber for greater weather resistance plus first class strength and insulation. This is supported by strong 34x57mm framing and floor joists.

All the wood has been pressure treated and carries an impressive 15 year guarantee against rot and decay. This guarantee is subject to periodic retreatment, which will also help maintain the wood’s attractive appearance. Providing you with another splendid saving on time and money, our manufacturer-approved, same-day installation is included with this premium summerhouse. You just need to make sure you have prepared a suitable solid, level base – concrete or slabs are recommended. With 4 custom made, large windows and 2 fully glazed double doors, this summerhouse is flooded with light creating a spacious environment.

The two side windows open to provide ventilation on warm days while the doors feature a premium 3 lever mortice lock and handle mechanism to ensure your belongings are kept secure. Adding the finishing touch, the pent roof’s modern design creates an overhang which provides shade and protects the front of this remarkable building. For longer lasting protection against the elements, this summerhouse features superior graded polyester-reinforced roof felt. Why not upgrade to a professional paint finish? Complete your summer house’s handsome appearance with a superior, durable paint finish. Aquatop is a water-based topcoat specifically designed for exterior wood such as windows, doors, conservatories and other garden buildings.

Flexible and durable, this micro porous protective film dries quickly and resists blocking when stacked. Adding to the summerhouse’s already robust treatment, this paint is also resistant to bacterial or fungal attack. Plus, the paint also resists UV damage, providing you with a summer house with a high-quality, long-lasting finish. For the range of colours, see the chart in the image carousel. Call our friendly, UK-based customer service team who will be happy to process your order or answer any questions you may have. For customers who choose to paint their garden building themselves, please note that it is recommended to wait 6 months before painting pressure treated wood.

DIY paint applied before this time may not adhere properly to the timber.
