Hello Forum members,
Need your advice in determining the principal elevation for my house.

Yellow line sets the postcode for my house.
Red line where the front door (Green marked area) is.
Brown line living room window and black line bedroom windows.

4m extension already done, half garage & half extension

I want to break this extension and build 8m extension, bule marked area.

Any thoughts appreciated.

Many thanks.

Is that your driveway next to the green front door? Without a photo of the street elevations and the information available here in the thread I would take the principal elevations as being the red one. I know there can be a little ambiguity for a corner plot and the technical guidance mentions the 'main highway & postcode but it also mentions the front of the house so I would suspect that would be implied here and would overrule the 'main highway'. But planners can be awkward dickheads so there is that too. If the front is the green door then surely;y the 'black' windows are side windows? Got some photos of the street views?
 
DCLG technical guidance quotes: "If a house lies on a corner plot where a side elevation also fronts a highway, there will be an additional restriction on PD to the side of the house."

If your red line is the PE then your blue line is a side extension and is therefore limited to 50% of house widtrh under PD. If the yellow line prevails then it's rear so up to 8m under LRE/prior approval would be my take.

FMT is spot on with his description of planners but unfortunately it's their view that matters.
 
Hi All
Thank you for your advice.
Yes its the driveway in front of front door. Please check the street view attached.
I have following questions:
1) I was searching my council website, but I cannot find any planning permission for this extensions (black box), so does this extension count as part of original house?
2) Garage is red box. Can I build another 4m side extension (green box) next to garage as PD?

Original house (which has a roof) width is 8m.

It will be much appreciated if you all can shed some advice.

Many thanks.

Is the front door the original front door? If so then that is the principal elevation. As for the extensions are they original or not you'll have to find out, that they're not on the council website is neither here nor there, council records online typically only go back a few years. You need to find out.

thank you for your reply. but in regards to green box side extension.
Do garage count as my side extension or I can build 4m side extension (half width of original house) adjoining the garage ?
Look forward to your input.
Many Thanks

It depends if the garage is fully attached to the house and was built at the same time as the house (or before 1948 if applicable). If it is then it is regarded as part of the original dwelling so the width calculation for the side extension is taken as half the width including the garage. So if the house is 8 metres wide and the garage is 2.5 metres wide the side extension can be 5.25 metres wide.
I looked in to this a few years ago and as with a lot of planning rules there is no actual written evidence and statutory documents to back this up but I did find some planning appeals that took this interpretation.
As Freddie has alluded to, the planners often just make stuff up to frustrate legitimate building work and impose their little bureaucratic power games so whether your local planning department actually accepts this rule is another matter.
