Hi all,
I’m trying to understand the 50% rule for a single storey side extension which I was hoping might be permitted development as the government website is quite ambiguous.
I’ve a detached house built in the early 1970s, 8.4m wide with plenty of space around it. The original owners were put a small single storey extension on one side for a utility room in the 1970s approx 2.7 m wide (2.2m deep)
I’m now looking to put an extension on the other side of the house to use as a garage/workshop which I’d like to be 3.6m wide
Can the 50% of the original build rule be applied to each side separately? ie 3.6m < 4.2m off I go…
Or, as I expect, it’s the total of all side extensions and therefore in this case I’d need to get planning? Ie (2.7m+3.6m) > 4.2m
TIA
