The right to privacy and light

When your local authority validates your planning they will send out consultation letters to your neighbours. Your neighbours have the right to add their comments and may attempt to hinder your application by raising the issue of sunlight being blocked, or that a window is overlooking into their property.

Your neighbour by law has a right to light and privacy which an easement not a restrictive covenant. An easement by English law is rights one individual has over another land. Easements override any planning permission you may have therefore it is critical that your design of your property is duly designed to overcome this barrier.

Minimum Ceiling Heights

All rooms should have a height of at least 2.1m-finished ceiling heght throughout the room. It is essential to get the planning right before building. If you’re planning to convert your loft you should take into consideration the joists which will be used, typically joist size for the floor are 8by2 treated timber and ceiling.

If you’re planning to building a single storey extension you can build a flat roof. The more go to roof style is a gable pitched roof. A gable pitched roof is sloped and provides excellent water drainage as opposed to flat roof. A gable pitched roof tends to have fewer leaks and has a longer life expectancy. The most promising advantage to a gable roof it provides the most ceiling space. Houses in the United Kingdom majority of ceiling heights are 2.5m having a gable roof extension will give the extension a much higher ceiling.

Avoid breaking rooms

Design is a really key element an extension can be a very hard challenge. Sacrificing more than you will be gaining will not be worth it. If your breaking a double bedroom to make a lobby to enter your extension which gives you an extra bedroom of the similar size will not be worth it. When you break a room to gain access into the extension you’re normally making a corridor, which is a waste of space.

The kitchen is a main selling point of a house. Your Kitchen should not be compromised when it comes to space, The kitchen and living rooms should all be accessed directly from the main hallway and not a lobby to get to it.

Party Wall Notice

A party wall agreement is a document produced by the two party wall surveyors acting for the owners of the land.You will need a party wall agreement if your extension included excavations or alterations near a neighbours boundary. There are certain requirements as to when you need a party wall agreement. Visit planning portal for more advice. The owner of the land planning to build the extension will normally pay the cost for party wall surveyors which your neighbour appoints.
