SPD4 – A Guide for Designing Housing Extensions and Alterations

This SPD comprises procedural advice, general design and amenity principles that are applicable to all forms of household development, more detailed advice for specific forms of development and special factors that may need to be taken into consideration with some householder applications. This SPD replaces PG2 – House Extensions (1994).

The draft SPD was subject to a six week public consultation period between the 7 March 2011 and 18 April 2011. Elements of the SPD were also part of an earlier consultation on Supplementary Planning Documents – Scope and Issues that took place in October / November 2009.
