Garden Buildings – Add Value to Your Home

Quality garden buildings do add value to your property and if you wish to sell, the sale-ability too. Constructed with the best materials and using the latest building techniques. Our garden rooms are strong and sturdy. They are highly insulated and sound-proofed as standard. Because a garden room is an extension of the house you can expect an excellent return on your investment. Extra space – adds value. Yet, unlike an extension it’s quicker, cleaner and more affordable. Also, due to the lack of red tape this makes a garden room even more appealing and achievable. Please visit our installation services page to see what’s included.

It looks good but you’d need a big garden to fit that into it!

I hope the new occupants enjoy it as much as we are enjoying ours.

Gareth Foster I'll have one of these plz for my old age

A perfect solution for many older parents/older children who want to be near their children but need their own space. If you have the space in the garden (if?) this is a good and very competitive price and overcomes many of the park home site issues. Having it custom built is the key so you have the design you want (personally I would want a separate living room). New Park homes remember cost from £250,000 to £300,00+ and yearly expensive site fees and they are only leasehold in the main. This looks so so much better if you have the land to put it on, with full security for your relatives (and no additional fees) and I believe it will be very popular in the future.

Just a decent shed would be good

Clare Hyde this would fit in your garden?...

How much plz?

All our garden buildings are individually tailored to your needs. Because the internal walls and ceiling are plaster skimmed. They provide a smooth internal finish to decorate to your own taste. There is no melamine, plastic wall cover-strips or silicone sealant. As, they will certainly turn yellow through the passage of time. Customers also have the freedom to choose the size, finish and external colour scheme. So, the building can blend with your environment and complement your home. We offer 21 factory applied colours to choose from. Our timeless beautiful facades are low maintenance and fire retardant. They are also a rot free alternative to traditional weatherboard.  Furthermore,  there is an aesthetic option to suit most project requirements.

Garden Building Construction

By using the very latest thermally efficient SIPs panel construction we comply with the current building regulations regardless of the size of your garden room or garden office. Please be aware that some companies supply garden rooms and garden offices that do not comply with building regulations. If the building is under 30m2 and is a metre away from the boundary, they do not have to. This can result in a building that is both structurally unsound and lacks the required amount of insulation. Our buildings can in-fact exceed the requirement by achieving insulation u-values as low as 0.10w/m2k. As a result, this combined with the use of modern panel heaters is a cost-efficient use of your garden building throughout all seasons.

Screw pile foundations are a local authority building control approved method. Therefore, they provide a fast, strong and permanent foundation. The combination of screw pile foundations and LABC approved, structurally insulated panels (SIPs). Results in a strong, permanent and highly insulated garden room or granny annexe. This modern method of construction comes with full structural calculations. Carried out by independent civil and structural consulting engineers on our behalf.
Depending on the size of your garden room, installation usually takes only four days. Larger granny annexe designs can take up to three or four weeks. This is due to utilities connection, kitchen and en-suite installation.

Garden Room Planning permission? Not a problem Logo.

Planning permission? Not a problem

Garden Buildings Planning Permission

All our garden rooms, garden offices and garden studios are manufactured to an external height of 2.5M. Therefore, avoiding the need for planning permission. There are a few exceptions to this: if your home is in a world heritage site, a national park, an area of outstanding beauty or if your proposed project includes sleeping accommodation. If your garden room does require planning permission we act as your agent and prepare all the necessary paperwork and drawings.  We submit the application on your behalf and attend to any queries that may arise.

Building Regulations

Depending on the size and use of your garden room, you may also need to comply with the current building regulations. For example, if the garden room exceeds 15m2 and if it is sited within a metre of your boundary, the garden room must be constructed of substantially zero rated non-combustible materials. The Green Room is a member of the Local Authority Building Control (LABC) scheme. Our buildings have been thoroughly vetted and therefore are compliant with all aspects of the building regulations. For further details on all the above see our FAQs page.
