The 7 x 7 Premier Corner Summerhouse is made using high quality materials to provide a premium finish. The space saving design means this building will sit neatly in the corner of your garden and will help you maximise your usable space. Whether you’re looking for a craft room or somewhere to relax with family and friends, this summerhouse offers a bright and welcoming space, with panoramic views of your garden.

The walls are manufactured using 12mm Shiplap tongue and groove cladding. This method of construction ensures a tight seal against the elements while providing a smooth finish. The roof and floor are formed using tongue and groove boards that lock together to form a strong, hard-wearing and robust build. We supply heavy-duty roofing felt to cover the roof and ensure your building has added protection against the elements. The two, full length fixed windows and fully glazed double doors, are fitted with shatterproof styrene glazing, a safer alternative to glass.

This building is made here in the UK, using ethically sourced timber. We supply robust fixtures and fittings with this summerhouse, including a lock and key for security. We offer a 10 year anti-rot guarantee alongside our standard 1 year manufacturers warranty. All you need to do is treat the building once installed, and again annually, with high quality timber preservative and a waterproof top coat, and your guarantee will be good to go! Manufactured here in the UK, using sustainably sourced and regulated timber.

Delivery and Installation Timeframes

We offer same-day delivery and installation services. While we strive to complete the installation on the same day, larger buildings may require more than one day for installation. You can find the estimated delivery and installation lead time for this product on the product page above. Our lead times are calculated in working days (Monday - Friday) and do not include Bank Holidays. These estimates are sourced from the manufacturers and serve as a general guideline, subject to fluctuations in demand. We provide this information in good faith to represent the expected delivery during that period. Please note that some remote areas might experience slightly longer lead times.

Delivery and Installation Procedure

Within 5 working days, Shire, the manufacturer, will reach out to you. This communication will be via either a text message or an automated telephone message. If a mobile number is not provided, the latter method will be used. This message will include the necessary website link where you can review and accept the assembly's terms and conditions. Prompt acceptance of these terms is crucial to avoid any potential delays. Once you've agreed to the terms and conditions, Shire will contact you within the specified timeframe to arrange the delivery and assembly date for your order. Please note that this process might take more time during peak seasons. Keep in mind that the installation team will require unobstructed access to your garden, a minimum of 18" clearance around the building, and a solid, level foundation. It's important to know that Shire's installation team cannot bring the building through your home, as they lack the insurance coverage for entering a customer’s property.

Delivery Day


The manufacturer, Shire, handles the delivery process. Typically, this item will be delivered using a 17-ton flat-bed vehicle, similar in size to a council refuse lorry. Deliveries are scheduled within the time frame of 7 am to 7 pm.
