Garden SIPs kits

If you dream of building your own inspiring workspace, home yoga studio, guest annexe or a special place for the kids to play, explore our range of sustainable SIPs garden kits, available in supply and install only. Every garden is different; that’s why we don’t offer a standard set of SIPs kit sizes. Our in-house design experts can produce SIPs drawings to match your specific project sizes.

Supply and install

Our professional team of site technicians can ensure accurate and efficient installation of the SIP panels. Ahead of accepting the quote, we estimate the lead-time and provide detailed forecasts for the manufacture and installation phases for your bespoke project.

Main contractors

You may prefer to have one main contractor overseeing all the works on your garden build project, so we’ve teamed up with a network of local main contractors who specialise in garden building installation. Essentially, they are responsible for all the work before and after the installation of the SIP shell structure. Likewise, if you’re a DIY enthusiast or have your own carpenter or builder, we’ll happily put up the SIPs structure once the site is ready.

What do SIPs kits include?

We provide a complete shell for your garden structure, containing the requisite number of SIPs to construct the walls, floor and roof, in the specific sizes for your project. You can then choose to finish your garden room however you wish. We aim to make life as simple as possible and supply all the elements needed for construction.

  • Detailed SIPs structure drawings
  • Production and assembly instructions
  • Insulated timber floor cassette*
  • SIP panels for the walls and roof
  • Timber splines, sole and wall plates
  • Specialist SIPs screw fixings
  • Specialist adhesives and sealants
  • Breather membrane

* ideal for sitting on ground screws or pads, we can also accommodation building up from a concrete slab

Foundations

A great building needs strong foundations. That’s why you’ll need to consider the type of base that your self-build garden kit will be constructed on. We recommend one of three types of foundation to be in place ahead of the SIPs structure installation.

Ground screws are galvanised pins that screw into the ground with precision to create a strong and level platform for your garden room, office or leisure building. Environmentally, ground screws offer a huge reduction of emitted carbon compared to a traditional concrete base. We recommend the Great British Ground Screw Company as our preferred supplier.

Pads offer another innovative solution, especially where rocky ground makes digging really difficult. Environmentally, the pads can also be a great way to reduce your carbon impact. That’s why we’ve teamed up with a preferred supplier that produces its pads from 100% recycled plastic – we recommend Jackpad.

Concrete slabs can also be used as the base for your SIPs structure. Through our established network of main contractors, we can recommend local professionals to assist with this process if necessary.

Planning permission

Some garden projects will need to apply to the local planning authority for planning permission prior to commencing any works. However, there are several scenarios where planning permission may not be required*. As a guide, outbuildings are generally considered to be permitted development, without the need for planning permission, subject to certain conditions. For example:

    • Outbuildings must be single-storey with a maximum eaves height of 2.5 metres and maximum overall height of 4 metres with a dual pitched roof
    • For outbuildings within 2 metres of the property boundary, maximum height is 2.5 metres
    • Verandas, balconies or raised platforms are not permitted
    • No more than half the area of land around the original house should be covered by additions or other buildings
    • If your property is a listed building, on designated land or within a national park, further restrictions apply

Whether you require planning permission or not, we’d love to help you understand the costs for the SIPs structure of your project.

* whilst we can signpost our clients to relevant literature, we do not offer a planning application or consultancy service. Therefore, we highly recommend that you check with your local planning authority ahead of embarking on your garden room project.
