Distance between rear of property and proposed new dwelling on corner plot

[JayBo1979]

Hi there,
We live in a 1930's semi on a decent sized corner plot. We had a meeting with the council planners and they agreed we had potential to build a small bungalow at the bottom of the plot/garden. This is our long term plan but in the meantime we plan to develop our current plot with a rear extension under PD (coming back 3 meters)

I have a couple of questions regarding separation distances

1) If we develop our current plot under PD with a rear extension coming back 3 meters will this affect the future planning application for the new dwelling at the bottom of the garden? I ask this as under PD there needs to be a minimum of 7 meters between the back of the extension and the rear boundary of the property but if we want to split the plot then this will be reduced to under 7 meters

2) The bungalow will be perpendicular to our house with no windows on the elevation facing the back of our current home. What are the rules about separation distances between the new dwelling and neighbouring houses? It seems that these only apply when they have windows facing each other?

See very rough image- rear extension to replace conservatory and shaded yellow. Proposed location of bungalow shaded in red. 

Thanks

The plot does not look big enough to accommodate this.  Is there anything similar around?

[JayBo1979]

Yes- the rest of the street is all very small semi detached bungalows. Plot will be almost 200 m2. Had pre app meeting and they agreed I could fit a small 1/2 bed bungalow (subject to design). Sketch is a VERY rough idea.

Hoping to get some advice on how not to jeopardise my chances of getting the PP by developing my current plot

Put detailed PP in for your bungalow in the garden, when it's approved fence off the plot, then put in PP for your own extension.

My plan would be

1) get planning for the new house.

2) Once you have that, speak the the neighbour about buying part of their back garden.  You already have plannig so they don't have the leverage of you needing part of their garden.  But if you can get part of their garden you can build the new house on a narrower plot and thus leave more of the plot with the original house.

 

You could even arrange it with the purchase of a bit of the neighbours garden as the new house would be entirely built on your garden and the bit you were buying from the neighbour would just be the back garden of the new house and the new house would not be built on that.

LPA’s have differing rules, policies and guidance on separation distances. You’d need to make sure the new dwelling fits well within the locality. You’d also need to make sure the new dwelling complies with the minimum GIA for that sizes unit, parking, bin/cycle storage and garden/amenity space.
