High-Performance Glazing for Year-Round Comfort
Choose from double-glazed glass roofs for maximum natural light, thermally efficient solid roof options for year-round comfort, or energy-rated glazing units that help keep heating costs down in every season.
Built-In Security You Can Rely On
Every lean-to we install comes fitted with robust, multi-point locking hardware as standard. Doors and windows are specified to meet modern security standards, giving you genuine peace of mind from day one.
The Most Versatile Way to Add Space to Your Home
A lean-to conservatory works precisely because it keeps things simple. The single-sloped roof fits neatly against your existing wall, making it an excellent choice for bungalows, side returns, or any space where a larger structure simply wouldn’t work.
Whether you want a sun-filled dining area, a productive home office, or a relaxed garden room, the rectangular floor plan puts every square foot to use. With Malbern Windows, your lean-to is designed around your home – not the other way around.

We’re a family-run business and our reputation in the local area has been built one satisfied customer at a time. From your first enquiry through to the final handover, you’ll deal with people who genuinely care about the finished result.
Frequently Asked Questions

In most cases, lean-to conservatories fall under permitted development and don't require planning permission, provided they stay within the relevant size limits for your property. We'll advise you at survey stage.
Yes - they're one of the best choices for bungalows. The adjustable roof pitch means the structure can sit comfortably against lower eaves without compromising headroom or appearance.
Absolutely. With the right glazing specification and an insulated roof option, a lean-to can be a genuinely comfortable room in every season, not just the warmer months.
Installation time varies depending on size and specification, but most lean-to conservatories are completed within a few days once groundworks are done. We'll give you a clear timeline before work starts.
A lean-to has a single sloping roof and a simple rectangular layout. It's generally more affordable and easier to fit into tighter spaces than Victorian or Edwardian designs, without sacrificing quality or kerb appeal.

We have had an outstanding service from Malbern, dating back to 2014 when they built my conservatory, over the intervening years when we needed a small bit of maintenance under the guarantee, and most recently when they have replaced the glass roof with a solid roof, transforming the original design. This has given us a brilliant new room in 2024 and made our house feel much more spacious and better insulated. The build team took care of the whole process, doing a very professional clean and tidy job. I can't recommend more highly!

Just completed a full conservatory build and all we can really say is that we are extremely amazed at the quality of the end result. Fantastic, brilliant, overjoyed, perfect, better than expected. After the initial meeting we had a picture in our mind of what we wanted but the end result is so much better than expected. We certainly can't complain, it is a job well done and money well spent. Now it's time to enjoy the final end result. A massive thank you to all involved.

Malbern recently built us a large conservatory and a garden room. This was a massive job involving levelling a terraced garden and putting in retaining walls in addition to the conservatory and garden room construction. They did a fantastic job, all the work was done to a high standard and any snags were quickly dealt with.
