Help With Old Loft

[Mattydoos79]

Hi pigeon guys I'm just writing on here to see if someone who keeps doos like to help with a project on my old loft, it needs a corridor put up inside and build nestboxes along the wall or new boxes hung up. The shed still got some life in it until I replace it in few years with a new loft. Also it's during autumn or winter I plan to do this when the pigeons stop breeding then resting.
