1960s Chalet Bungalow

1960s Chalet Bungalow Survey
We recently carried out a survey on a 1960`s chalet bungalow which had been modernised and extended in more recent years. At the rear of the extension and overlooking the garden, there was a full height and width gable end UPVC double glazed picture window. Although an attractive feature, it was found that the window flexed excessively when pushed laterally.

On further investigation it transpired that building regulation approval was not granted for the installation and we recommended that the client obtains a structural engineers report to establish the structural stability of the window. The engineer concluded that the window was structurally unsound, dangerous and recommended that the UPVC window be replaced with an aluminium framed window, designed by a structural engineer, installed by a specialist and approved by Building Control. 

A safety barrier should be installed on the outside and inside, to protect anybody from injury should the window be blown in, sucked out by a strong wind, or by impact damage. The structural engineer made the comment that a UPVC window should never be installed in such a wide and tall opening and it is important in such circumstances that full enquiries are made to ensure such an installation complies with building regulation approval.
