One of the best ways to add an extra living space to your home (without the need to acquire planning permission) is by adding a conservatory. There are, however, plenty of other advantages that come into play with this highly sought after home improvement, such as increasing the overall value of your home, boosting natural light and providing a pleasant transition to your garden.

Over the best part of the last two decades, 3SG has developed a wealth of experience in designing and building conservatories in Olney and the surrounding areas of Buckinghamshire, in a range of materials, styles and designs. Some of the most popular designs include:

  • Gable
  • Georgian
  • Lantern
  • Lean-to
  • P-Shape
  • Victorian
  • T-Shape
  • Orangery

Many old-fashioned conservatories have proven to be unusable much of the year, being too hot in the summer months and too cold in the winter, and this is largely due to the fact they included a polycarbonate roof that wasn’t heat reflective or thermally efficient. With 3SG, you’ll be guaranteed a superbly crafted conservatory that’s designed to be used all year round.

We understand that every family will outgrow their home at some stage and if you love your home and your location, whether it be Olney, Buckingham, Milton Keynes, Bedford or Northampton, a brand new conservatory by 3SG can offer you more space, style, functionality and value.

Absolutely. Our specialist team of engineers have helped a huge range of homeowners in Buckinghamshire, Bedfordshire and Northamptonshire finally make full use of their conservatory with a series of smart upgrades. Whether you’re in need of a thermally efficient polycarbonate roof that reduces noise, or a contemporary self-cleaning glass roof that’s solar reflective, allowing just the right amount of light to come through, we can ensure your existing space is completely transformed and fit for all seasons. We’re also specialists in Guardian Roof replacements, and this is a fine option if you’re looking to completely transform your conservatory into a room that feels more like an extension that you can enjoy all year round thanks to a revolutionary, insulated tiled roof.
