Hi,

I am in the process of planning an extension however I need to know what is actually considered as ?

Regs state "The term ‘original house’ means the house as it was rst built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so."

Our 1936 semi has a utility room which is original to the house, this measures about 2.5 meters from the rear of the house (where it joins the existing kitchen).

As I am planning to knock this down and re-build but a bit bigger, do I take the 3 meter measurement from the interior wall of existing utility (so the party wall between existing kitchen and utility) or from the end of the existing utility (so could go to a max of 5.5 meters from the kitchen wall) - not that I want to, I just want to make it a total of 3.5M

A bit confused as the utility is original to the house!

Many thanks in advance guys

In theory, it would be possible to extend 3 metres from the rear wall of the dwelling across the rear elevation - so your end result could be an extension projecting 3 metres from the wall of the house, and 3 metres from the wall of the utility room (resulting in a 5.5 metre 'extension' at the utility room) However, if you knock the utility room, you will then only be entitled to build a 3m from the rear of the house. It's a permitted development right to extend the house only, not to demolish a portion and extend. Sounds silly, but that's the rule.
