Start with three air standards: cleaner air (less dust/odor), controlled humidity (no musty feeling or mold),
and reliable air exchange even when the house is closed.
Design AC for stability: zone by real use so you do not cool the entire house.
Protect bedrooms from noise and vibration by managing equipment placement and routes.
Make condensate drainage inspectable. Hidden ceiling leaks are expensive later.
Design lighting and outlets from activities.
Define four lighting scenes: arriving home, relaxing, working, and hosting.
Place outlets based on the real layout of beds, TV walls, desks, and kitchen appliances.
Add plumbing shut-off valves by zone (kitchen, bathrooms, garden) so repairs stay local.
Provide service access to pumps, tanks, filters, and key joints.
If you add smart features, start only with friction reducers: lighting scenes, security, leak alerts, timers, irrigation.
Manual control must always exist.
Before handover, test like real life: run multiple taps, test every AC zone, cycle lighting scenes,
and document pipe/cable routes before finishes close.
