From the sublime to the simple, we can make your conservatory dream become a reality. From a modest lean-to design to a stunning Victorian classic, the choice is yours. A cost effective and enjoyable way to add light and space to your home, a conservatory can offer a welcome retreat with resplendent views of your garden and the great outdoors. And, because most domestic conservatories are exempt from mainstream Building Regulations and Planning permissions, they can be installed with the minimum of fuss.

A variety of classic styles of conservatory are available in both uPVC and aluminium systems, including the ever popular Victorian and Edwardian designs. We use two main roofing systems in either aluminium and uPVC, both manufactured by Ultraframe Quantal, leaders in the specialist design and manufacture of custom-made, hand-finished conservatory and orangery roof systems that are innovative, stylish and durable. Our popular conservatory styles include:

An aesthetically pleasing classic style that generally suits all house styles from period to new build, the Victorian usually comprises of a 3-facet or 5-facet bay front. With a variety of styles and glazing options available, the Victorian is still probably the most popular style of conservatory.
More angular in shape than the Victorian, this is a classic style with clean lines and a rectangular or square flat fronted projection. A variety of styles and glazing options are available including single-ended or double-ended designs. This style is also sometimes referred to as “Georgian style”.
The simplest conservatory style and a popular choice for cottages and bungalows, the Lean-To is rectangular in shape with a flat angled sloping roof. This style makes the best use of available space constraints and can be adapted to fit awkward or unusual spaces. Remodelled with a steeper pitched roof and bold modern colours, the Lean-To conservatory is a popular contemporary style choice.
The popular P-shape is the ideal choice for the larger conservatory and combines a mix of both Lean-To and Victorian styles. By blending two styles into one you can create a conservatory big enough to offer two separate living areas. The Victorian section helps to create the P-shape that gives this style its name and can be built as either a 3-facet or 5-facet design.

A step-up from the standard conservatory, orangeries have now become the new up and coming product to have. Historically a place for the cultivation of citrus plants, the classic orangery design was originally separate from the main house. It would have had stone built walls with large sliding sash windows and a glass roof on timber rafters with a box gutter all round inside the parapet wall. Today the term “orangery” is less well defined, referring largely to a glazed building with a solid roof and roof lantern, usually used as part of the main home. An orangery combines the best features of a traditionally built room extension with the added benefits of “living under glass”.

An ideal addition to a flat roof to provide natural light into the room below, roof lanterns offer great potential for transforming an otherwise dark and gloomy space. A lantern represents an accessible and affordable alternative to many conventional roofing treatments and can take many different forms, from simple pyramids to elegant octagons, or larger rectangular hipped roof lanterns. An ideal solution for extensions, roof lanterns can be positioned to define a particular area within a space; a kitchen island for example, or the dining area within an open-plan kitchen/diner.
