Exterior Finishes for Bespoke Garden Buildings

Customise Your Bespoke Garden Buildings Exterior Finish

The exterior finish of your garden building plays a major role in both its appearance and long-term durability. At CS-Garden Offices, our exterior finishes are designed to deliver a sleek, modern look while providing exceptional protection against the UK climate.

Unlike traditional timber garden rooms that require regular staining, painting or treatment, our buildings use plastisol-coated galvanised steel panels, creating a highly durable and completely zero-maintenance exterior. This advanced material will not rot, warp or deteriorate over time, ensuring your garden office or garden room maintains its appearance for many years without ongoing upkeep.

As part of our insulated modular building system, each panel also contains a 75mm polyurethane insulated core, delivering excellent thermal performance and impressive U-values of around 0.13, helping to keep your garden building warm in winter and cool in summer. This means your garden office, gym or studio remains comfortable all year round while also helping to reduce energy consumption.

With a range of modern colours and design options available, our exterior finishes allow you to create a garden building that complements your home, enhances your outdoor space and provides long-lasting performance with minimal maintenance.

Superior exterior finishes built to last

Zero maintenance

We use a plastisol coated galvanised steel giving a superior sturdy structure that will never rot or deteriorate in years to come. So unlike the traditional timber rooms, you will never have to varnish or treat your garden room.

Superior insulation

Our modular panels have a 75mm polyurethane insulated core giving tremendous U-Values of 0.13. The very best on the market. This awesome insulation gives massive energy savings, even in the harshest of winters a small electric heater is more than sufficient to keep a comfortable temperature.

High security

Over the years our buildings have stored anything from home theaters to scientific test chambers holding over £150k worth of equipment. You can be assured that our buildings offer the very best security values. From the standard 6point locking systems to our doors & windows to the High-security steel reinforced doors

Vermin Proof

In timber based garden rooms there are hundreds of small joints and cracks for unwanted insects & vermin to access. With our modular panel system, there are very few panel joints all of which are sealed with a colour matched mastic keeping even the smallest of insects out.
