We have bought part of an 18th century mill and are in the process of converting it to live in. The building is not listed and is not in a Conservation Area. One of the covenants in our deeds (imposed by the vendor, who still lives in the unit next door) was that all windows must be timber framed with putty pointed single glazing.

We are consulting with Building Control who say that there is no reason for us not to comply with current regs regarding the energy efficiency of the window glazing, ie. we will not able to use single glazing (though the timber frames are fine).

So, my questions are:

  1. Does Building Control overrule the restrictive covenant?
  2. If we do have to comply with building regs and fit double glazing, what implications does this have with the vendor being able to impose the covenant on us?

Any and all advice would be much appreciated!
