Insulation is one of the most important factors to address in any building, but especially garden rooms. Being located away from the house, or at least semi-detached, garden rooms need professional insulation to keep them warm and habitable during the winter and to expel the heat in summer months.
You can choose one of our award-winning designs from off the shelf or opt for a bespoke design to cater to your specific needs. Whether youâre looking for a summer retreat to entertain guests, a private garden office to work from home or a winter snug room for cosy nights, we can design and install it.
All designs come with a price match guarantee, so you can rest assured that not only will you receive the best bargain for your insulated garden room but you will also be receiving the best quality (all designs have obtained the Q-Mark certification of quality).

All garden buildings at EHB are built with insulation in mind, as itâs one of the most important benefits customers look for when buying an outdoor garden building.
A professionally insulated garden building can save you a small fortune in electricity bills as they are designed to retain heat and stop it from escaping through the walls and ceiling.
Additionally, weâd always recommend pairing our insulated garden buildings with double-glazed windows to maximize both security and insulation â as double-glazed windows also play a crucial part in retaining heat as well as deflecting it in the summer months to keep the garden room cool.

If you are considering converting your garden room into an annexe for semi-permanent or even permanent living, full insulation is absolutely crucial. Our fully insulated garden rooms are built using French oak beams which are fantastic insulators, and we can design the building to accommodate any type of insulation for walls, ceilings and even underfloor heating.
However, be mindful that you must take into account the rules and regulations regarding building a live-in garden room or garden annexe. If you are unsure of these rules this is something we can help with. Simply get in touch with our team if you have any questions or refer to our permitted development or planning permission guidelines.

Work with us to design your bespoke dream garden room or choose from one of our stunning premade builds for a faster installation. If youâre unsure of what youâre looking for, our team can help navigate you through your options so you get the most out of your purchase.
Once you have chosen your insulated garden room, we deliver and install it â however, please allow 6-8 weeks for custom and bespoke builds. In this scenario, we would send you planning drawings to ensure that youâre happy with the proposed build before charging you the full price.

We do not currently offer any insulation services, however, our buildings are made out of the finest French oak timber to ensure that insulation properties are exceptional. However, for padding and underfloor heating needs, we may be able to put you in touch with a contractor.
Garden rooms vary in price depending on a number of factors, such as size, features (double-glazing, ceilings, doors etc). However, you can expect to pay between ÂŁ6,000 and upwards of ÂŁ30,000 for larger, complex builds with unique features. For a bespoke quote, please contact our team with your requirements.
You should not need planning permission for insulated garden rooms as they fall under permitted development. For more information on these terms and how you can assure youâre not breaking any rules, please visit our permitted development or planning permission page.
