Article 4 properties map

Does an article 4(2) direction mean that development is not allowed?

An article 4 direction only means that a particular development cannot be carried out under normal permitted development rights and therefore needs a planning application. This gives a local planning authority the opportunity to consider a proposal in more detail. Article 4 per se does not prohibit any work you may want to carry out, it merely means you need to apply for planning permission.

Permitted development, put simply, means the type of work that people are generally allowed to do without the need for planning permission (as defined under the General Permitted Development Order 2015. In a conservation area such as ours there are certain things, such as demolition or part demoltion of buildings and walls, that do however need planning permission. This applies to all houses within the conservation area.

In addition those properties covered by Article 4(2) are legally obliged to apply for planning permission for certain other alterations that are facing the street (or deemed visible to the “public realm”). These include house and garden walls, gates, windows, doors, roofs, driveways, paths. Repainting or like-for-like repairs are not included.

Original John Smith development: 1911 – 1926

*Original John Smith style means those properties which were part of John Smith’s original development 1911 to circa 1930.  There are later properties that were built to emulate or “pay tribute” to that style. e.g. 18 Leigh Road (2009) 33 Blenheim Avenue (2000)

Some properties built during the original development may have been built by John Smith to different designs, though are more likely designed by other architects (TBC). This includes many of the houses on the west (common) side of Westbourne Crescent.

Later infill development

The majority of houses later than 1930 were built on infill sites, for example  36 -44 Blenheim Avenue were built on the large plot that originally served as John Smith’s yard and offices. Others built on are plots that presumably did not sell during the original development. Some houses were built following WWII due to  bomb damage (10 and 32 Oakmount Avenue).
