Garden Room House Extensions
Several garden room companies featured on this site also offer house extensions alongside their standalone buildings. Like garden rooms, these highly insulated extensions use various construction techniques, including traditional timber frames, Structural Insulated Panels (SIPs), and light gauge steel frame systems. Most companies manufacture the core structure off-site in optimal workshop conditions and deliver it in modules for rapid on-site assembly – this is where the term flat-pack extensions originates. Compared to traditional brick-and-block building systems, this modular approach is far quicker and far less disruptive to your daily life.
As you can see from the examples below, house extensions come in a range of styles, from beautifully glazed, traditionally styled designs by specialists like David Salisbury to more contemporary, cubist-inspired structures. Designers will work with you to create a size, layout, and specification tailored to your needs, offering vast palettes of materials to personalise your extension – from traditional brick finishes that match your house to low-maintenance composite options.
Most of these companies offer a turnkey service, managing the entire project for you – from design and planning approval to final decoration and sign-off by building control. While the majority of options focus on single-storey extensions, you’ll notice companies like Bridge Garden Rooms also offer two-storey designs.
A flat-pack extension is one of the quickest ways to add space to your home. In many cases, your new room can be assembled and ready to use within just a couple of weeks.
