So what does this mean?
Well to ensure that your site can be built out to Part L 2010, make sure that you've firstly registered the site with building control before 6th April 2014. Then you’ll need to start work on site before 6th April 2015. If you don’t think you’re going to be able to start work before this date, make sure you've got some flexibility in your budget to accommodate improvements to the building fabric and services to ensure compliance.
If a site contains multiple dwellings, then works to a single dwelling in line with the definition above, will mean that the site has commenced and locked into the applicable Building Regulation for the duration of the development.”
