It's usually possible if you are in small towns to contact local construction companies, see what/where they are planning to build (usually semi-detached or row houses) and customize the inside (plan and fixtures) as much as possible. It's really hard to do it without an architect with so much less space available, but even then you still have a lot of freedom.
