Self-build-insulated garden rooms give you access to the Waltons product range at a reduced price.

Self-build-insulated garden rooms give you access to the Waltons product range at a reduced price. While we normally offer free installation as part of the package, a great way to cut costs is to elect to erect your own garden room. If you choose this option, you’ll receive full step-by-step instructions with your product, and if you get stuck, there’s a helpline you can ring for advice from our experienced staff. To figure out whether self-build is for you, just open the PDF document in each product description and view the installation instructions. For more information on buying a garden room, please look at our guide to buying an insulated garden room.

How to build a garden room base

Due to the size and weight of an insulated garden room, either a paving slab or concrete base offers the best foundation. A job for a competent DIYer or your local builder or landscaper, building a base requires a reasonable level of fitness as you’ll need to dig down and then create foundations from hardcore before you lay your slabs or mix and pour concrete. If your site is on a slope, you’ll also need to clear and level it before you begin. For a better idea of what’s involved, you’ll find full step-by-step instructions for building both in our guide to building a shed base.

How to build a garden room

More DIY Garden Room Info

Opting for a self-build insulated garden room is a great way to access the Waltons range while achieving a significant cost advantage. Our garden rooms offer versatile extra living accommodation in the heart of your garden. Elegant and functional, not only do they make great offices, treatment rooms, garden retreats, and entertaining spaces, but they also add value to your property. If you’d like to know more, here are answers to some of the questions our customers often ask us about our insulated garden rooms.

Can I use my garden room all year?

Our insulated garden rooms are designed to offer comfort no matter what the British weather throws at them. The thick (choose between 72mm and 100mm thickness) double-skinned timber walls contain a layer of EcoQuilt insulation – a multilayer foil product that offers insulation properties equivalent to 100mm of standard rock wool. Both floors and ceilings are also fully insulated, and we fit double-glazed windows as standard. Adding a heat source will, of course, make your room that much more comfortable. For more information, please refer to our guide to heating a garden building in winter, where you’ll find lots of helpful info.

Can I sleep in my garden room?

As a comfortable, cosy space, we’d be disappointed if you didn’t occasionally nod off in your beautiful garden room, but you shouldn’t use your building as extra sleeping accommodation unless you have planning permission to do so.

Do I need planning permission for my garden room?

The vast majority of our customers do not need planning permission for their Waltons insulated garden room. In fact, we design our buildings to comply with all the relevant height and building size restrictions. There are, however, certain exceptions – listed buildings, for example, and for builds that take place in the front garden or take up more than half of your garden. If in doubt, you should refer to the government planning portal.
