You can choose which side the single door is on your building and if you want just one opening window or an opening window on both sides. You can also upgrade the floor thickness if you have heavy office equipment. We also have paint options, guttering options, and a choice of uPVC door colour.

Evolution Insulated Garden Office
Fully Insulated

Fully Insulated

For an office you can use all year round, the My Den comes fully insulated with our high performance multi-foil insulation. Our multi-foil insulation has multiple layers which lock the temperature in the colder months and deflects the heat in the warmer months. It also provides you with the same U-values of 120mm glass wool insulation. It is also much thinner which means you have more room inside compared to using conventional insulation rolls.

To make assembly as easy and as quick as possible for you, we have specially designed the panels to have the multi-foil insulation and internal cladding pre-fitted, meaning that the panels simply slot together without any additional fitting for the internal cladding.

Hand Crafted

The My Den is built by our fully trained product development team using hand-selected graded scandinavian slow grown timber and state of the art 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

My Den comes with pre-assembled panels which we line with insulation before it’s delivered to your door. Making the installation of My Den 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 My Den experience a pleasant one.

Fully Insulated Metal Roof

For the ultimate roof covering the My Den comes with our heavy duty, fully insulated metal roof as standard. Made from corrugated metal outer shell and premium gloss internal finish, our metal roof provides increased weather protection and increased longevity of your building.

Our metal roof panels also come with a solid 40mm insulated core, which means that they will keep your building warmer in the winter and cooler in the warmer months. The roof panels are also easy to fit and don’t require any additional roof covering, making them faster to fit than a timber roof which requires a roof covering material. The metal roof is also our lowest maintenance roof option and will protect your building throughout its lifespan.
