    Good afternoon all,

    I am proposing to build a rear extension to my bungalow. The bungalow has a standard pitch roof with the soffit at the top of the windows. (eaves height 2.7m).

    Looking through the Permitted Development rights it states that the eaves must be no higher than the existing. Does this mean that you cannot have a standard flat roof extension to any bungalow which would naturally have a higher eaves (unless the floor to ceiling height was considerably lower). Or is this excused for bungalows? The new eaves height would be 3m.

    Any thoughts would be greatly appreciated.

    Correct. Under PD, the proposed eaves cannot exceed the original eaves irrespective of the type of dwelling.

    I’ve had this on another bungalow project of which there was an ‘original’ first floor rear dormer. So in that case, one would assume the maximum eaves height would be that of the dormer and not the main roof.

    thank you for your response. It is interesting as I suspect many, many single storey flat roof extensions have been built to bungalows which in theory should have had Planning Applications but were overlooked as you would expect a simple flat roof extension to be PD

    Pre-2008, that was more than likely the case when the PD rules changed. 2.7m is quite high for normal soffits anyway. What height is your ceiling, approx. 300mm higher than soffit level?

    Why would you assume that? Are there no eaves at ground floor level?

    Design the flat roof with a tiled eaves.
