Get these right early and the rest of the build gets easier.
Orientation is everything
Face the main living areas and windows north for free solar warmth and natural light. The same aspect gives you the best position for solar panels later.
The indoor-outdoor connection
In a 60 sqm flat, link open-plan living to a deck or patio with sliding or stacker doors. A bar-style bench works too. Include the deck, weather protection and door specification in the quote; those features affect cost and the usable footprint.
Roof design drives cost
A simple skillion roof is cheaper to build and easier to maintain than a complex pitched roof full of valleys and hips.
