2024 Guide to DIY Garden Room Kits

2024 Guide to DIY Garden Room Kits

Published: 22 March 2024
Reading Time: 4 minutes 41 seconds

Garden rooms have become a favoured way to extend our homes, offering a quicker alternative to traditional house extensions. Positioned away from the main house, they create a secluded retreat and can serve numerous purposes. While most garden rooms are installed by professionals, building your own offers several benefits, notably significant cost savings.

When self-building a garden room there are two routes you could take: designing and sourcing materials yourself, which demands considerable time and may involve trial and error, or opting for a garden room kit. A kit provides a proven building system with all components delivered simultaneously, accompanied by a detailed assembly manual. This approach allows you to enjoy the construction process while ensuring a timely finish so you can quickly begin enjoying your new space.

This guide will showcase various garden room kit options. Some kits come complete with everything needed for construction, while others provide the insulated core structure and exterior finishes for quick weatherproofing, leaving you to source your choice of interior finishes. There are also kits that offer just the insulated core structure, offering you the flexibility to select your own exterior and interior finishes for a custom look.

Jump to the 'Where to Buy' section

Benefits of Buying a DIY Garden Room Kit

Choosing a DIY garden room kit over a professional full-service installation or a from-scratch design offers several advantages:

  • Cost savings compared to full-service installations.
  • Shorter lead times than full installations.
  • Confidence in a proven building system, avoiding the uncertainties of a self-designed project.
  • A one-time delivery of all materials, eliminating the need to source individually.
  • Faster construction compared to building from scratch.
  • Comprehensive assembly instructions and video guides.

How Much Could You Save by Self-Building a Garden Room?

Purchasing a garden room kit results in savings of 20% to 35% compared to a fully installed garden room, mainly by eliminating the cost of on-site labour, one of the project's most significant expenses.

What is included in a garden room kit varies

It's important to note what each garden room kit includes when comparing your options. Most kits do not come with the foundation system, requiring additional budgeting for this component. While some companies offer foundation kits as an add-on, others leave the foundation choice, like a concrete slab or a plinth foundation system, up to you.

What is included in the kits varies between companies, with some including the insulated core structure, exterior cladding, doors, windows, and roofing system for a weatherproof shell, leaving the interior finishes and electrical system arrangements to you. Other companies allow you to configure your kit with everything you need for the project. For those seeking more control over finishes, SIPs kits might be an attractive option, offering the core structure with the option to separately source exterior and interior materials for greater customisation.

Remember to budget for the final electrical connection between the garden room and the house, which must be completed by a qualified electrician in compliance with Part P of the Building Regulations.

How long does a garden room kit take to build?

Garden room kits are designed for ease of assembly, with pre-cut, numbered panels that fit together easily. Typically, two individuals can make a garden room weatherproof within two to three days, depending on the building's size, ensuring a swift transition from the construction phase to using the space.

Where to buy a self-built garden room kit

Many garden room companies offer kits alongside their full installation ranges. Additionally, some SIPs manufacturers provide kits that can serve as the foundation for a multi-layer build-up. With each of these options, you engage directly with the company, placing your order, and they then deliver your kit. Use the links below to further explore your kit options:
