Conservatory Roof Replacements
Our most popular service – and with good reason. If your conservatory is uncomfortable or rarely used, replacing the roof with a solid, insulated system is the most effective way to fix it.
We use Supalite tiled roofs to turn cold, noisy rooms into warm, energy efficient spaces that feel like a proper extension.

Orangery Extensions
Combining brick piers with large windows and a central glazed roof, orangeries offer a more solid, modern take on a traditional conservatory.
They’re ideal if you want extra space that feels integrated with the rest of your home – perfect for kitchens, dining rooms or open plan living.

Modern Conservatories
Clean lines, slim frames and high-performance glazing – our modern conservatories are designed for contemporary homes and updated layouts.
They’re great for creating bright, open living areas that flow naturally from the rest of the house.

Lean To Conservatories
Simple, practical and space-saving. Lean to conservatories are ideal for bungalows, terraced homes or smaller gardens where space is limited. They’re quick to build and can be customised with modern finishes, glazed roofs or solid insulated options.

Insulated Conservatories
Whether you’re starting from scratch or upgrading an older build, we can create a fully insulated conservatory that’s usable all year round. From warm roof systems to energy efficient glazing and upgraded doors, we’ll help you design a space that’s comfortable whatever the weather.

What’s the best way to improve an old conservatory?
The most effective upgrade is replacing the roof. A solid, insulated roof can transform your conservatory into a usable, energy efficient space that feels like part of your home.

Most conservatory replacements fall under permitted development. If there are any planning or building control requirements, we’ll guide you through them and handle the paperwork.

Absolutely. We specialise in warm, insulated conservatories that regulate temperature all year round – using solid roofs, double or triple glazing and modern materials that improve energy efficiency.
