The land and the house.

Right; the fascinating details;

The land we have purchased is 650m2 of mostly flat (dips at the front and rear) rectangle.

(This 'un)

The house, in which the living area will mostly be oriented North, is a home and income plan comprising a 4 bed/2 bath main house and a 2 bed/1 bath minor dwelling attached to the back (east) side of the main house. 

The plan is to rent the back house out to help with the mortgage as well as make the property more appealing when we look to sell (more on that later). 

There's a Right Of Way/Lane thing at the back of the section. Turns out that we own 1/6th share of it (along with 5 neighbours). As a result, we're approaching Council for permission to have a vehicle crossing for the back house. This is massive for us as Council rules are you have to have parking for each dwelling, and at the moment, the slab for the back house pushes the whole build off the southern boundary. Naturally, we want to be as close as we can to that boundary to maximize our northern yard.

We've signed up for a house and land pckage and so far the experience (which consists primarily of tweaking the design to what we want. Then tweaking back again when we change our mind) has been mostly painless. It helps to be extremely clear with the design guys as they tend to fixate on one thing and ignore the rest of what you're asking. They've been (touch wood) good at letting us take responsibility for portions of the build that we can do cheaper. We do expect their largesse to falter at some point as we suspect everything they don't arrange reduces their chances to clip the ticket.
