Spend ages designing the house, down to the last detail. You very soon
acquire a suite of library objects like bogs, cookers and fridges
etc..take time and get them right - and then you can quickly assemble
while layers of structure, fixtures, plumbing and the like, and see the
house before you even build it.

I can "see" it roughly now. Gimme a while to work out the details.

There's a lot of "Construction to satisfy building regs" and "Size to
fit available space" on the drawings so far.....

It can be of benefit to find a design you nearly like and make a few
alterations.
