Modern Conservatories

Bespoke Conservatories

We can build custom designed conservatories, giving you more control over the appearance and construction of your conservatory.

You can customise the conservatory roof, windows and doors, as well as installing conservatory heating or fans. We can design a custom conservatory to suit the particular shape or size of your site.

High Quality Conservatories

KJT Builders use only the highest quality materials in the construction of every conservatory. Conservatories are really an extension of your house, and so should be designed using sympathetic styles and materials.

Our conservatories are available in a choice of brilliant white UPVC, PVCU, traditional hardwood and other materials. Our highly-skilled bricklayers will use complementary materials to match the brickwork in your conservatory to that of your house.

Conservatory Windows

We use only high quality Duraflex window systems, manufactured and tested to the highest standards. Our conservatory windows are made using a choice of styles of toughened glass, including Guardian and Pilkington K glass.

As well as helping to control temperature and improve security, Pilkington K glass is designed to exceed the ”Part J” Building Standard for energy efficiency, thereby helping to reduce greenhouse gas emissions.

Conservatory Roofs

KJT Builders use high quality K2 roof systems on all our conservatories, and these can be fitted with a choice of glass or polycarbonate. These BBA-certified roof systems are designed to look great as well as being secure and easy to maintain.

Conservatory Planning Permission

Many people worry about getting planning permission and satisfying building regulations for conservatories.

KJT Builders have been building conservatories and sunrooms for over 12 years, and so have built up a great deal of knowledge with regards to planning permission in Portsmouth and the surrounding areas.

For example, all our drawings are carried out by a professional architect, and our conservatory foundations exceed required Building Control standards.
