We’ve had a fair few sunny days this year, but the British weather can be notoriously fickle.

With a conservatory, you can enjoy the garden whatever the weather while remaining safely under cover.

Conservatories are versatile too, and can be made into sitting rooms, playrooms, dining rooms, dens or even home offices.

The problem, though, is that they’re often boiling when it’s hot, and freezing when it’s cold, so you must make sure they are properly equipped for extremes of temperature.

Many conservatories have low brick walls with glazing above, but you can increase the brick ratio which makes it easier to insulate and add radiators.

Conservatories are usually at the back of the house, but if there’s a sunny spot at the side, you may prefer to put yours there. Its position can make a big difference to how usable it is, so consider how the sun moves across the plot during the day.

An east-facing conservatory will only get morning sun, while a west-facing one will be cooler in the morning and hotter towards the end of the day.

Conservatories that face north should get angled sun first and last thing and so won’t overheat on hot days, but they can be bitterly cold in winter.

A south-facing conservatory makes the best sun-trap, but it will get extremely hot on a warm summer day.

It is, of course, a shame to spend all that money on a conservatory and only be able to use it when the weather allows, so efficient heating and cooling systems are a must to make the most of your investment.

Portable heaters aren’t a good long-term solution and while extending your home’s central heating system into the conservatory may not be cheap, powerful radiators are one way to counter all that glass when it’s cold. Installing electric heating is often easier – with under-floor heating, you have a nice warm floor and warmth that radiates upwards.

Blinds help to insulate a conservatory in winter, as well as keeping it cool in summer, and provide privacy.

Your conservatory should also be in proportion to the garden and house. The best way to get an idea of the size (and position) is to mark it out in the garden with spray paint or string and pegs, and change it if you’re not happy with it.

Like anything in your home, there are different styles of conservatory, from ones with ornate period features to plainer, more contemporary ones.

UPVC conservatories are white or wood effect, and they’re affordable and require little maintenance.

Alternatively, aluminium is really strong, durable and versatile, but it is expensive. Wooden conservatories require more maintenance than UPVC and aluminium – but they are environmentally-friendly, as long as the wood is sustainably sourced.

The best conservatory is one that matches the period and style of your home so that it becomes a seamless addition.
