Conservatories are less hassle and more affordable than extensions, making them a fantastic choice if you need extra living space. But will you get your investment back plus change when you sell?

The truth is that a conservatory can add or subtract value from your house depending on how stylish and well-made it is.

A modern, insulated conservatory that matches your house could add up to 10% to the value of your home. However, a poorly constructed and old-fashioned conservatory will turn buyers away and attract low and cheeky offers.

Here are the factors that impact house prices:

Garden to conservatory ratio

A key factor to consider is your ratio of garden and living space.

As a general rule, a conservatory should take up less than 50% of your garden space, which is also the ratio requiring planning permission.

Cramming a conservatory into a small garden will devalue your house because most people want a garden to enjoy. The trouble is that if you go too small with your conservatory, it can add no usable living space, defeating the point of it.

Simply put, you need to strike a balance; if a conservatory takes up 50% or more of your garden, don’t bother. If you have an odd-shaped garden perfect for the build, or it will take up less than 40% of your garden, it’s worth considering.

Conservatory style

Old-fashioned conservatories with thick beams, polycarbonate roofs, and timber or half brick builds are no longer in vogue. People want aluminium and composite conservatories with panoramic double glazing and a glazed or solid roof.

Victorian and Edwardian styles are eternally popular but do not match new and modern homes. New builds do better with a gable or lean-to-conservatory roof, finished in anthracite grey or another trendy colour.

You must match your conservatory to the period of your home. Otherwise, it will look out of place and devalue your house.

Conservatory quality

High-quality conservatories are fully insulated and built to last a lifetime, with a minimum ten-year guarantee on the frame and glazing.

The quality of construction is also essential, with the fit and finish of the build inspiring home buyer confidence. You should be proud of your conservatory, with every bit of detail from the window frames to the floor perfect.

Roof construction

A polycarbonate conservatory roof will devalue your house because everyone is savvy about their lack of efficiency and noisiness during rainfall.

A double-glazed roof is a better option, but pay more for solar glazing – solar glazing reduces glare and reflects 90% of the sun’s heat.

However, a solid roofing system is the best option overall. Solid roofing systems have a glass-reinforced plastic frame and engineered tile construction. The tiles match the roof of your house, creating the look of a proper extension.

Summing up

A conservatory built in the style of your home using modern materials can add around 10% to the value of your house.

Avoid these traps – old-fashioned styles, polycarbonate and glazed roofs without a solar treatment, and eating into more than 40% of your garden.
