Our clients had been considering a conservatory as permitted development on the rear of their 1970’s end of terrace house. Other internal alterations were also required and we were approached to obtain Building Regulations consent for these works. The budget for the conservatory was £20 000 + VAT. We persuaded them to consider a more substantial extension, still within permitted development limits and with the same budget. The advantage of our proposal was that it would be fully integrated into the house as a true addition to the current living space, and could be used 24/7, 365 days a year. The cost was agreed at £22 000 + VAT, excluding external works. They had not considered it was possible to achieve a ‘proper’ extension to their home at the same budget as a quality conservatory and are delighted with the result.
Contract value £28 000 excl VAT. (£22 000 extension). Homeowner contract.
Conservatories are often considered as low cost additions to living space which can be constructed without the need for planning or building regulations consents. Permitted development rights under planning legislation have recently been relaxed and relatively large extensions can now be undertaken without planning consent. Building Regulations exemption does apply to conservatories, but only if they are separated from the house by external quality doors and windows, and are unheated spaces. In many cases people construct conservatories and then remove internal walls or doors to integrate them into the house. As soon as this is done the extension is no longer a conservatory and requires Building Regulations consent. In most cases, due to the amount of glazing in the extension, it will not be possible to get this consent.
