We have a three bed semi with garage to the side.

The idea we would like to consider is demolish the garage and build a two story extension and extend the roof correctly over it ie not flat roof. The garage would be within it.

A couple of houses in the street have done it and it increases the number of rooms to 5 proper double rooms a bathroom and two ensuite. Plus garage is wider so better.


Question I have is the neighbour on one side which is north of our property ie think light here. Would they reject the proposal. I'd guess light loss would be say up to possibly one hour more than currently. IF they did reject what would the revised options ? How does it impact relations with a neighbour

Up to the neighbour in question I guess...

Would have thought if similar planning had been approved then the precedent had been set as far as the council are concerned. No idea if yours does obviously - but my local council website allows you to see any plans that have been submitted previously which can help if you're looking for any ideas

Do planners still use the 45-degree rule? It's a rule-of-thumb about judging the impact on habitable rooms (only) in neighbouring houses.

It's described here: http://www.planning-applications.co.uk/righttoligh... and there's a basic video here: http://www.justaskdino.com/45rule.php

Precedent is one thing, but planners' attitudes can change and what might have been allowed 20yrs ago, might not be allowed now. Plus, if there's a curve on the street, etc the geometry might be different.

You can't just measure light loss in hours of sun, there is the permanent loss of diffuse light from the portion of sky obscured. This is why removal of an isolated tree to the north can still make a garden seem much lighter.

The chances of you reducing their light to a level where they could take private civil action outside of planning is very slim.

So that probably means the only essential requirement is planning permission.

But let's face it, no neighbour is going to be happy or even neutral about something that affects his property adversely, so the sooner you involve the neighbour in your proposal, the less the likelihood of an objection and/or simmering animosity.

^^^ This.

The '45 degree rule' is still in widespread use, but it's only the first stage rule-of-thumb that Planners use to discourage what they consider to be inappropriate development. If you want to argue the case beyond that, the benchmark is usually taken as the Building Research Establishment guidance document 'Site Layout Planning for Daylight and Sunlight'. This starts with the '45 degree' rule of thumb but then offers methodologies for more accurate assessment of impact, and my experience of these is that you've got to do something incredibly overbearing before you fail the test.

You may need to consider overlooking issues as well, however, along with design principles that usually seek to ensure that the extension is aesthetically subordinate to the original dwelling.

Seek professional advice.

The other thing is how long does planning permission last?


Also a question they have two large trees in their rear garden which late in the evening pbscurlers sunlight. They are fruit trees and they have never harvested anything from them. So based upon thT logic I could have a tree blocking the exact same level of sunlight from a tree that I planted.

As said I'd guesstimate sunlight loss would be max one hour vs as is and the sun is from c10-11am at this tome of year.

i'm not an expert on planning, but I'm not aware of any process for the neighbour to approve or dis-approve your plans.

yes, they can lodge an objection, but planners will determine your application on its planning merits compared to the local plan - ie set of development policies and procedures.

people referring to expert help will include architects who know these, and hopefully know how to draw up plans that will meet both yours and the Council's requirements.

of course, many are judgements, but again this is where your "expert" comes in.


it also depends how friendly you are / want to be with your neighbour. In my view: people extend. Your neighbour will just have to get used to it, and leave it to the planning system to determine what is acceptable or not.

3 (or 5?) years rings a bell.

Forget about their trees, and what trees you could plant!
It has nothing to do with any extension light issue.
And what they don't do with the fruit?????????????

Try and discuss it with the neighbour if you want to be neighbourly, but just get on with the application - your achitect won't design anything the planners would obviously reject.
