I've found some good resources for prefab and modular spaces for both workshops and larger dwelling spaces. www.studioshed.com (I don't work for them or benefit financially, i'm just a fan) is the one i'm leaning toward as we have a nice sized yard, South Beacon Hill, with an independent alleyway for access and parking and we can get the build for $80k including kitchen and bathroom, all electrical components, doors/windows etc (I would have to put it all together or hire someone to do that) but not incl permits, site work, utility connections and foundations.I've been quoted in the range of $260-360K for a complete package with a design build service which is out of our league but the DADU' presented do look awesome.
