Bird nest boxes suitable for bungalows

Hi everyone, in our previous house we had a starling nest in the roof eaves at the front, and a sparrow nest in the roof eaves at the back. We've recently moved to a bungalow and are getting some building works done soon, including an extension with a pitched roof. I was just curious if there are any other bungalow owners who find birds nesting in the roof eaves or is a bungalow too low for birds to take up residence? If there is a chance that birds will want to nest should we make sure there's access points to the eaves for birds when we get the extension built? And would nest boxes work in a lower position on the bungalow walls?
Thanks for any help and input.
