Hand Crafted
The Grandmaster Diplomat is built by our fully trained product assembly team using hand-selected graded scandinavian slow grown timber at our facility in Nottinghamshire, in the cusp of Sherwood Forest. Developed and tested by our highly experienced team designers, our grandmaster range is our most durable range of sheds. Designed for multiple uses and to be able to be customised to your requirements, the Grandmaster Diplomat Summerhouse is a building that you can enjoy for many years.
All of products are picked, checked and packed for delivery making sure everything meets our high standards.
We do the hard work for you
The Grandmaster Diplomat Summerhouse comes with pre-assembled panels which means assembling your building couldn’t be easier. With doubled up framing where the panels join, our Grandmaster Range really is built to last. All of our panels are manufactured and checked at our facility, to ensure your building meets our high standards. Made with high quality shiplap cladding, your building is stronger and more durable so that you will have a longer lasting building.
Build to your specification
The Grandmaster Diplomat Summerhouse can be fully tailored to your requirements. To make this even easier for you, we offer a wide range of upgrades for your building so you can get the most out of it, whatever its use. If you are looking for a building that you want to spend time in all year round, we offer double glazing for your windows and doors, and also a further upgrade to our upvc windows and doors, giving you increased security and even better insulation for those colder months.
If you are looking at using your building for a home gym, or require heavy furniture items to be stored inside your building, we offer the upgrade to our thicker flooring so that it can support all of the extra weight. For an even more heavy-duty building we also offer a full cladding upgrade from 11mm to our 16mm thickness. If this wasn’t enough options already, we also offer the choice of upgrading your roof felt to our EPDM rubber roof to fully protect your building from the elements, and increase the longevity of your building.
