A shared-workspace campus for you and your friends would work out then? You can picture it as a shared-workspace town if that is more appealing to you. Living quarters, parks, etc. on one side of the highway. A shared-workspace campus hosting multiple companies/teams on the other. Living and working stays strictly separate, everyone has a short commute and you still have all project members available on-site at the same time to reliably work together and gasp actually meet up when required.

To answer your question, I do not want to bring work into my home. BYOD resolves most of the factors that would make me want to provide my own office at home.

May I ask how you currently manage to live close to your family and friends and (because I have to assume you are surrounded by like-minded individuals) their families and their friends and so on? Frankly, I find this very unrealistic, but maybe that's because my friends and family are spread out across the globe.
