The french doors are fully glazed, and there are three fixed, full-length windows to provide plenty of light. The styrene glazing is shatterproof for added safety, making this a space the whole family can enjoy. You can use this contemporary summerhouse in various ways. Add a desk to create a garden office or workspace for your hobbies. Add lots of comfy seating for entertaining guests, or make your own cosy hideaway to relax with a cuppa or something stronger.

The pent roof design and wide-opening french doors let you open up the summerhouse on those balmy summer evenings. The pent roof also helps the rainwater runoff, and the simple, modern summer house design will sit neatly next to a wall or fence. High-quality brushed chrome handles and hinges add a stylish finish to this contemporary timber garden building. You can also lock the doors, so you get peace of mind. The exterior finish features smooth-planed timber cladding to complement the Maine summerhouse's contemporary design. It also makes it easy to add a treatment or paint colour of your choice to personalise the finish. This summerhouse's appealing design and multifunctional space will help you add a garden room the whole family will love.

Upon Delivery

Your order is delivered either kerbside or driveway and will be delivered on either a 3.5T, 7.5T or 18T Lorry. Unfortunately due to health and safety and insurance liabilities the driver will not be able to take your goods around to the back of your property but may upon request place the product at the side of the house if there are no access or restriction issues. We would not risk damaging your property whilst delivering a product to an unsafe location. Unfortunately, we will not be able to go through your property.

We would recommend against arranging for a third party to install the building before it's been delivered and checked that all parts are present, as we cannot be held liable for any third-party costs.


Orders with Assembly 

The lead time for our installation option is around 12 weeks from the date of order. With the installation option, the majority of orders will have their delivery and installation on separate days; there will be a small number of orders which will have delivery and installation on the same day. You will be advised by the manufacturer's installation team which category your order falls into.

Depending on the installation option for your order, you will be contacted within the delivery timescale and given a date for either delivery/assembly on the same date or a separate date for delivery and assembly.
