sparrows and garden birds

We live on a housing exec estate, and this summer all houses and flats are having new rooves. The flat opposite us has had sparrows, great tits and chaffinches nesting in the attic through a gap in the eaves there for many years. They will almost certainly lose thier nests. As work has now progressed to the first house in our row, I've ordered a sparrow terraced nest box from RSPB, I've also bought a couple of single ones from pet shop. I'm slowly providing nests for a lot of  migratory and home birds. In April I errected two swallow nest bowls under our balcony, I may need to move one nearer to the wall after they leave again as an attempt was made to line one of them but I think the bird was aiming to build towards wall. I was delighted to see that they'd acknowledged it. I'm hoping to errect my garden bird nest boxes next week to give the soon to be evictees time to check them out. I hope this will help them. I'm also hoping to errect a swift box next spring as I've noticed a lot of them here this year.
