If you’re thinking of turning a conservatory into an extension, don’t rush into it. It may seem a simple job of just getting rid of the glazing and maybe extending dwarf walls but you are asking for trouble – both structural and legal – if you don’t speak to your local authority and if you fail to do your homework first. For example, are you 100 per cent sure that your foundations will take a heavy extension (usually they won’t) and that the thermal properties of your extension will conform to the stringent new environmental considerations (ditto)?

The reasons why homeowners like turning a conservatory into an extension

One of the main problems with most conservatories is that they are only fully functional when the weather is within narrow limits. Whether you have a glazed or polycarbonate roof, there is little to stop the transfer of heat out of the room which means that once the sun goes down, any heat that has built up over the day will quickly dissipate. On the other hand, when the summer mid-day sun is shining down through your roof, it quickly heats up the surrounding air, largely due to the greenhouse effect which stops the sun’s rays escaping. After a while the conservatory becomes too hot to bear.

So one reason why homeowners prefer turning a conservatory into an extension is so they can use it all year round.

Some people accept the fact that one of their rooms is basically out of action for over half of the year until they make plans to sell it. Everybody knows that adding usable space to a house is the surest way to increase its value and it makes perfect sense for the outgoing owners to begin converting their part-time conservatory into a full-time reception room – or even a bedroom.

Electrical items are also a problem when you have a conservatory. Almost all electrical items will warn you against exposing them to extreme fluctuations in temperature which makes most conservatories an absolute no-no. That’s even before you get to the issue of excessive glare and UV damage.

Ultra-violet rays from the sun are also behind the fading and bleaching damage that you see on fabrics and other sensitive materials used in a conservatory – there is a reason why you only tend to find plants and rattan furniture in a conservatory!

If at this stage you’re getting depressed about your prospects of turning a conservatory into an extension then the good news is…there is another way!

Alternatives to turning a conservatory into an extension

If turning a conservatory into an extension seems a bit of a headache then there are alternatives. Conservatory roof conversions for example give you many of the temperature conserving benefits with minimal structural changes and no red tape to wade through with Building Regulations.

There are now several kinds of specialist lightweight roofing systems, complete with insulation, designed to be used with conservatories (for example see our Supalite roof review). These roofing systems are solid and opaque, preventing both glare and the direct transference of sunlight.  They also have a much lower u-value than glass or polycarbonate which means they transfer heat only slowly, stabilising the temperature within the room, even when the sun has gone down.

Conservatory roof conversions are a compromise between the convenience and cost of a conservatory and the comfort and economy of an extension.

However, if you do decide you would prefer to go the whole hog and can afford the time and expense it takes when turning a conservatory into an extension then this video gives some idea of the process…good luck and enjoy.
