Conservatories button

A new conservatory can transform your home allowing you to enjoy a new spacious room that lets sunlight and fresh air flood in and brings your house and garden together. Today’s conservatories are no longer limited to being just an ‘add on’ to your home, as many homeowners are choosing to create unique spaces to use for a kitchen/dining area, living room, children’s playroom, study, swimming pool enclosure or detached garden room. Benefiting from our highly energy efficient glazing, weather sealed door systems and with optional heating, it means your conservatory can be used all year round.

At Alpen we offer a range of conservatory styles from heritage designs through to cutting-edge, sleek contemporary conservatories with bi-doors that open up large areas, blurring the edge between a room and terrace or garden. We can also create beautiful orangeries or more conventional brick walled rooms with glazed feature lanterns or Skypod Skylights.

Doors and windows for our PVCU conservatories are constructed from the same batch of high quality materials so we can ensure that the frames, colours etc match perfectly.

All Alpen PVCU doors are designed to be low maintenance so they don’t need to be painted or treated. Occasional wiping with a damp cloth is all they need to maintain a fresh, good-as-new appearance. Furthermore, PVCU doesn’t warp or swell, so you can be sure your door will maintain its original  appearance and keep performing for many years to come. With internal webbing and thick PVCU walls, our conservatories are designed to withstand the rigours of everyday use.

We offer a range of styles of windows and doors which can feature frosted, patterned, leaded, Georgian Bars or stained glass. Our door options include inward or outward opening and low or flush threshold.

We also offer a non-standard range of colours which may take a little longer to manufacture, please ask for details. We can also supply with wood finish exterior and a white interior. Guttering and trims can be selected to match or complement the exterior. For that historic look we can create Edwardian, Victorian and Tudor style crestings for your roof.


For a real cutting edge contemporary look we can create a stunning conservatory in aluminium. Featuring a sleek profile which is minimal and modern, aluminium is popular with homeowners and architects because it’s low maintenance, won’t rot or warp and is designed to give many years of trouble-free performance. By using aluminium bi-fold doors we can also create a design where nearly all of one side of the conservatory can totally open up, allowing fresh air and sunlight to flood in. Our aluminium range also benefits from high specification thermal and sound insulation properties to help create a peaceful and warm environment inside your home.

Alpen aluminium conservatories can be finished in a range of RAL colour coatings which allow homeowners and architects to create a unique look.
