Good idea about the radiant floor heating. Might be nice to have the guest/inlaw suite on a separate heating system, since aged relatives etc often like it warmer than I'd like. Don't want to give up too much headroom, though.

Not hung up on real hardwood vs engineered vs laminate, as long as it matches the main house decently well.

Anyone know about sound insulating a ceiling, to reduce footstep noise from overhead?
