Loft Conversion Building Regulations Guide

Loft Conversion Building Regulations Guide



Before building a house or adding an extension to your home, you need to get, you need to get two official things out of the way. The first is building regulations approval and check whether panning permission is needed. More than likely you will need both. Sometimes, you can get away with just needing the building regs  approval only of your planned extension is within certain limits.

These are covered in under roughly six parts and are related to house extension within UK only.  Rules might be different within other European countries, USA and Canada. The first is area.

Area

 
If the area in which you are planning to build an extension will cover more than half the original area of the garden, then you will need planning permission.

Boundary

 
Be prepared to get planning permission if the height of your extension is more than thirteen feet (13ft) [4m] high and within two feet, six inches (6ft 2in) [2m] of a boundary irrespective of the part of the boundary.

Conservation Area

 
As expected, the environment comes first and preserving what cannot be easily replaced is paramount. Any building extension within an area of exceptional natural beauty requires permission.

Height

 
This is very much a key factor in any build. Any addition to the house which is going to be higher than the highest part of the house roof will require the go-ahead of planning authorities.

Listed Building

 
As part of cultural heritage and highly supported by the National Trust, consent must be sought and obtained for any listed buildings. In fact having extension works on any listed building requires up to five (5) types of consent depending on the extent or complexity of the house extension.

  1. Firstly and most importantly is the planning permission for building operations no matter how small.

  2. Listed building consent is needed there will be modification or demolition to a listed building.

  3. If for some reason the building constitute part of a historic monument, then scheduled monument consent will be required.

  4. Lastly, although not expected of home users, you may need advertisement content. This is only needed if advertisement and signs are going to be erected on the building.

  5. For those who wish to take on such a challenge in building an extension on a listed building, one will be pleased to know that for obtaining consent for works on the listed building that there is a considerable concession available in that the cost of alterations to listed buildings used as charities or as private residence are zero rated for VAT. More information can be obtained from the National Trust.

Projections

 
Any part of an extension that projects beyond the main wall of the house facing a highway or that is less than sixty five feet (65ft) [20m] from a highway requires panning consent.

Residence

 
If the extension is going to be an independent dwelling house then seek planning agreement first.

Volume

 
The most obvious and notable reason for building a house extension is to create extra living space. To guidelines laid down by the authorities stipulate that for an increase in volume of the original size of the house of the following amount (which ever is greater) that planning permission should be obtained:

  • In Scotland: General category, 28.7 sq yd [24 sqm] or twenty per cent (20%)

  • Terrace houses: A ten per cent (10%) increase or sixty five and a half cubic yards (65.5 cu yd) [50 cu m], up to a maximum of one hundred and fifty cubic yards (150 cu yd) [115cu m]

  • Other houses: A fifteen per cent (15%) increase or ninety one and a half cubic yards (91.5 cu yd) [70 cu m], up to a maximum of one hundred and fifty cubic yards (150.4 cu yd) [115cu m]


Town and Country Planning (General Permitted Development) (Amendment) (No 2) (England) Order 2008



As part of the Government’s reform of the planning system the Government introduced new changes on 1st October 2008 to the permitted development rights for householders. The Government’s stated intention was to make it easier for householders wanting to extend their homes without the need for planning permission.
