The steel frames are straightforward and fast to erect and may be suitable for a competent, skilled and confident DIY team. To fully realise the long term benefits of these hard wearing structures, however, a professional installation is recommended.
Erection of the steel frame is an important part of the installation process, but any plumbing, electrics, waterproofing and indeed preparation of the area prior to installation should all be completed to a high standard. All building regulations must be adhered to and qualified, professional tradespeople will also provide guarantees and insurance. The design and manufacture of garden rooms from Permaroof mean that the installation process is fast and easy for experienced fitters, leading to reduced labour time and cost.
