randomly hit the keyboard and produced:

I am planning to extend a 1960’s Gable ended Bungalow. The height to
the roof of the Bungalow is just over 4m at a 30 degree angle. Ideally
I would like to make the extension the same height elongating the
Bungalow but when researching Extensions most seem to drop a metre and
have a step in the roof height however this would reduce the ceiling
height.

So what are the problems of extending the existing Gable end roof at
the same height?

Often the reason extensions as you describe are lower is due to
planning constraints. To avoid terracing (if all houses were extended,
a row of semis would end up looking like a terrace), they ask for the
extensions to be set back, usually by a metre. This has the knock-on
effect of reducing the ridge height if you keep the roof pitches the
same.

It may sound obvious, but check with Planning as to what would be
acceptable.
