Swifts v Building Regulations Q+A

Swifts v Building Regulations Q+A
About:


Stephen Fitt suggested I write to you.

I spend a fair amount of time designing nest boxes for Swifts, which also turn out to be popular with House Sparrows.

Some of them end up as products and others are custom solutions.

Some are external, fitted to the outside of a building and others are internal: Swift bricks and the like.

I recently strolled around a building development where Swift bricks had been conditioned.

Apart from the fact that less than half of the conditioned nest boxes had been installed, I looked at the ones that had been installed and thought we must be able to do better than this.

I have some draft designs, and have started to build some prototypes.

The aim is to produce something that satisfies the following:

  • Simple as possible for the bricklayer
  • Unobtrusive in the wall
  • Suitable for both retrofit and for new build, though the new build market would be somewhat larger than the retrofit market.
  • Accepted by Swifts and Sparrows.

Back in 2013, I built some prototypes and installed 6 of them under people’s eaves – since then all 6 have been occupied by sparrows or swifts – 3 pairs of Swifts.

My target would be for boxes high up in a gable, near the roofline, embedded in the wall but also intruding into the cavity but not penetrating the inner leaf.

I do not think my ideas would push the boundaries beyond what accepted products do

e.g. Schwegler, Ibstock, Manthorpe and CJ/Vivara pro

However, I am not up to speed as much as I would like about building regulations relating to Swift boxes embedded in walls.
