How do you count properties that are demolished for redevelopment under BV64?

Please could anyone let me know your views- if a property is demolished, as part of a redevelopment of the whole site, should we be counting this as 1 unit (the demolished property) ot the total number of new units that are provided on the site?

We have a couple of long term empty properties in particular where where we have been encouraging the owners for several years to take some action, and now looks like they are pursuing planning applications for approx 7 units on each, so would liek to ensure we include the correct figure once these are developed, and will aslo obviously affect the year its counted in.

Any views would be much appreciated. Thanks.

Hi Amanda
This question comes up from time to time.  The simple answer is that there is no basis in the old BVPI64 or in the NAEPP Guidelines that accompanied BVPI64 for counting newbuild properties on sites that have been cleared via the demolition of empty properties.   This is after all a fairly common occurrence on brownfield sites and to allow such an interpretation would start to make a mockery of the whole idea of measuring local government work in bringing empty properties back into use (or demolishing them).  There is no relationship, in many cases, between the number of new builld properties constructed and the number of empty properties demolished so that "performance" in respect of empty properties becomes meaningless.  That is different from the situation where a building is converted, where the number of new dwellings is broadly speaking related to the volume of the original building.
I am aware of one or two authorities that have counted newbuild on sites where properties have been demolished (in one case restricting the number to those that were built on the footprint of the demolished building and ignoring others).  But I think that is an unacceptable blurring of the boundary between empty homes work and regeneration.
