Benefits of Modern Extensions

Energy Efficient

With energy prices what they are right now, it is very important to ensure that your home is as thermally efficient as it can be. With our extensions, the frames and pillars are designed with this specifically in mind to ensure that your home isn’t excessively burning through energy to keep your home warm. 

Our insulated double glazing will also endeavour to keep you equally comfortable in the middle of winter and the height of summer. Our modern extensions will ensure that your Carshalton home will keep your carbon footprint down and low energy bills.


With a modern extension from Castle Conservatories, you can be assured of an investment that is built to last. Concerns about decay and deterioration will become a thing of the past. Your new installation will stand the test of time and prove to be a worthwhile investment. 

With exceptional durability comes exceptionally low maintenance needs! It takes a wipe down from a damp cloth to ensure that your modern extension remains a shiny example of how wonderful your home is.


We know, at Castle Conservatories, that homeowners want to make sure that their homes are as secure as they can be. With us, you’ll receive top of the line locking systems and mechanisms that have been tested against the highest standard to ensure they meet modern requirements of security.

With our double glazing, you can be assured that the glass in your home is not the structural weak point you may fear. You can enjoy a good night’s sleep, knowing that your home is protected from intruders.

Modern Conservatories

A modern conservatory from Castle Conservatories fulfils all the modern expectations for extensions and goes above and beyond in terms of thermal efficiency, security and aesthetic appeal.

Modern Orangeries

The modern orangery is a wonderful addition to all homes, whether they be traditional or modern. Brickwork combines with natural light to create a private but attractive modern extension that is both unique and practical. 

We ensure that all of our orangeries are fully customisable to your specification so you can be assured that your modern extension fits your Carshalton home perfectly. We provide solid, tiled and lantern roofs for our orangeries, with each system providing an aesthetically pleasing feature and all the practical benefits you have come to expect.
