The History of Oxford

The city’s university dates back to the 1300s, and is of course famous worldwide, but it’s not all college quads and dreaming spires. Ethnically diverse and expanding rapidly, Oxford is also a modern, working place, and not everyone based here is involved in the university.
Areas are diverse, too. Choose from convenient family suburbs such as Botley, bohemian, cool districts like Jericho or cosmopolitan, vibrant East Oxford or unpretentious Cutteslowe.
As you’d expect, just about every property type you could mention can be found in and around the city – including terraces, grand Edwardian and Victorian villas, townhouses, conversions and detached homes. There’s quite a bit of building going on across Oxford, too, particularly at the higher end of the market.

With an older building, you may be more limited in how you can develop it, especially if it lies within one of Oxford’s conservation areas. We can help with timber-effect windows, sliding sash windows or Edwardian or Victorian conservatories to enhance period properties. Equally, our replacement doors suit Oxford homes whenever they were built, from elegant bi-folding ones to versatile, energy-efficient composite models or great value uPVC.

Conservatories in Oxford

Conservatory Styles

Conservatories in the Victorian or Edwardian style, as well as lean-to models, remain popular with our customers and tend to suit older properties. You could have full-height glass walls or dwarf walls with glass. Orangeries are another option, originally devised to cultivate orange trees, and which have solid walls inset with glazed panels or full-length doors and a glass roof. They tend to be rather more substantial structures. Contemporary conservatories tend to be bespoke designs, with a wide choice of styles and materials available. And modern ones can even work well alongside period buildings, as long as they are sympathetically designed.

At Isis Windows, we offer orangeries and sunrooms, Victorian and Edwardian conservatories and bespoke designs together with a great selection of stunning roofing options. And our products and service come with a full guarantee, giving you genuine peace of mind. Remember, most of our business comes from personal recommendations.
