I find there's a (not quite) happy medium - some things are way overdesigned, but trying to use all the space in a large is basically impossible under a 400 item limit unless you love wide open spaces or absolutely no detail whatsoever. And then you get into silly problems like my current one, which is that to make a rainy mood mansion I've also committed myself to re-walling every single room I intend to use so the 'native' windows don't ruin things...
