side extension query

[JulietRomeo]

Hello, my neighbour has a detached property with a converted garage on one side which has been converted into living space with a bay window at the front and 4 square/domed rooflights along the flat roof which are equally spread along the depth of this now living space.
On my side, I would like to extend my much smaller property which has a lengthy driveway along my side of the boundary into a double storey extension (living space on the bottom, bedrooms on top). The depth of the property would be identical to the neighbours property. However due to the roof lights would my neighbour be able to argue to veto my plans for a double storey and effectively reduce them to a single storey in order not to impact his roof lighting setup?

The neighbours property is a rental so I don't have an easy 'go knock and find out' option unless I press the agents for a chat.

Thanks
JR

Do you have to have windows in the side?

[JulietRomeo]

Hi, to allow light into the landing area a window is likely on the top floor about halfway down the depth. Could be a frosted one if this was the determining factor.

The window overlooking your neighbour would probably be an issue with planning.
Speak to an architect to get some advise on what they think would get approval in your area.

[Spudler]

I'd say you'd struggle on that one.
Have you looked at roof lights?

[BlueMeganeII]

Did anyone actually read the ops post? He is worried his double height extension would block light thus causing issues with his neighbours roof lights and that he would thus be limited to a single story extension.

[JulietRomeo]

Yep bingo. Perhaps could have been clearer with my opening mail.
Side window or no side window it still a stonking wall going up that will affect their light lumens entering the roof lights I'm sure...

[Fizzsimba]

That's why I suggested you speak to an architect, they will be able to advise you on this matter and should have access to a right to light specialist.

How far from the boundary will your extension end and how far from the boundary is the neighbour's property?

[barryrs]

Right to light is not a material planning consideration IIRC so a two storey extension couldn't be refused on that basis. They could try and argue loss of amenity however a chat with your neighbors could well be half hour well spent and negate any objection in the future.

[JulietRomeo]

The neighbours single storey side extension is ~6 inches from the boundary, with their guttering then nudging right upto the boundary itself. I would be looking to do similar on my side.

I'm awaiting the owner to contact me as agents can't give out their details.

Speak with the planners.

In my opinion the rooflights are secondary windows and will not be considered.

Building a 2 storey extension tight to the boundary is becoming more difficult to get approved nowadays.

This ^^ there is no way anyone can give you a definite answer on here with the details we have. Give them a ring and you can submit a query with a sketch of what you intend to do and they will then give you a lot clearer answer (costs around £50 here, not sure if varies county to county).
They are actually really helpful if you keep them informed of what you are doing/planning on doing.
