Fully Insulated

The Evolution Apex Roof comes fully insulated as standard making it perfect for use all year round. The multi-foil insulation locks heat in during the colder months and deflects heat in the warmer periods. Meaning that Evolution is always at a comfortable temperature.

We’ve made sure that the Evolution is secure so that all your belongings are safe, as standard Evolution comes with a high quality mortice lock. This gives you the peace of mind that your space is protected, along with a thicker and doubled up framing which gives your building extra strength

Hand Crafted

The Evolution is built by our fully trained product development team using hand-selected graded scandinavian slow grown timber and state of the art composite exterior cladding in house at our facility in Nottinghamshire, in the cusp of Sherwood Forest. All of products are checked before delivery making sure everything meets our high standards
Hand Crafted
Team Hard Work

We do the hard work for you

The Evolution Apex Roof comes with pre-assembled panels which we line with insulation before it’s delivered to your door. Making the installation of the Evolution easier for you or your installer, whilst saving you time and money.

Alongside this we have created a set of easy to follow instructions which are sent out with every building, making your Evolution experience a pleasant one.

Create your own Evolution

We’ve built the Evolution Apex Roof with upgradability in mind, allowing you to customise your building to your exact specification. We offer multiple upgrade options for the Evolution, we can upgrade your floor to 19mm or 28mm for heavy duty applications. To give extra protection to your Evolution we have included our EPDM rubber roof as standard, which will give you 50 years of protection. With its modular construction we can configure your Evolution to perfectly suit your garden or outdoor space with extra side doors and windows. To go along long fixed double glazed windows which come as standard.

Easy Self Assembly

When it comes to assembly, your building has been designed to be simple to install where a large building is as simple to assembly as a smaller building due to be being constructed from modular panels. Your building will be supplied flat packed in modular panels with instructions and all of the fixings required. The instructions show how each panel is positioned and fixed in place clearly in simple stages. This means that if you have some basic DIY knowledge and experience you will be able to assemble your building. It is recommended that two people assemble the building so that the parts can be held in place and fitted at the same time, for safety and to handle any heavier parts. Before the building arrives, a solid level base must be prepared ready before assembly and you should also have space outside your house for the delivery to be made. Our panels are also pre-lined with our multi-foil insulation so that all you need to fix for the insulation is the internal cladding, making the build an enjoyable experience.

The sales team were excellent and answered all our questions. Delivery was as arranged and the delivery driver couldn’t have been more helpful. The timber and its pressure treatment is good quality and the construction plans were easy to follow. We are delighted with our new summer house.

Brilliant company, so easy to deal with. The summerhouse arrived on the date they said a two great young men erected it within about 4/5 hours. Extremely efficient and friendly. As for the summer house, well it’s great and so affordable. My son uses it daily as a man cave with a sofa ,TV.and games console .
