For the architect

Doors and windows: what needs to be done so rain water does not pool or flow in? Are drain holes needed?

Should bathroom waterproofing go up to 1.8-2 m, or is the whole wall better? Is reverse waterproofing on the ceiling of the floor below needed? Should waterproofing be tested by flooding for 72 hours?

Have 1 master switch for the whole house (e.g. when away): press it to cut all power, except the fridge, cameras and wifi / network. Besides the fridge, cameras and wifi - what other equipment should keep power when the master switch is off?

How will the house be protected against lightning?

Should electrical devices and sockets be recessed into the wall?
