Yes wonderful use of 2 x 4's as I am sure the pigeons will appreciate the new roost. But on a more serious note single family homes with a community atmosphere does not necessarily need to be compromised for good architecture. Batay-Csorba has proposed a similar build on Pacific Avenue in Toronto that has no front door open to the street that is removing valuable parking spaces and increasing the height and depth that is normally allowed for west end properties.

The devil is realy in the details
