Yes, an extra door for the garden with a dirt lock. We have a shower installed there. And in this area (there is also a toilet and a sink) a floor drain is installed. That means it can simply be sprayed out or wiped down. For the work shoes, there is a shelving system on the wall; on the shelves are shoe trays that can be sprayed clean if needed. Basically, nothing is standing on the floor there, so it can quickly be vacuumed or mopped.
Generally in the house: many free surfaces, furniture (bathroom!) hanging on the wall. Also, few open shelves in the bathroom; better to store things in drawers and cabinets.
If curtain rods are installed, make sure the curtains can be quickly removed for cleaning.
Use bookshelves with doors. Coffee table with drawer, so coasters, tissues, bottle openers, remote controls, etc. can quickly disappear from view and dust.
In the kitchen, make sure little is standing or hanging in the way. So no wall rail with spatulas, but everything packed in drawers. Mount suitable gliders under chairs and furniture so they can be easily moved for cleaning. Plan sufficient sockets – also place a cleaning closet with vacuum cleaner and mop upstairs, so everything doesn’t always have to be carried up separately.
Hang the TV on the wall or on a swivel arm. In the office, hang the computer under the desk or mount a mini PC on the monitor. Also attach screen(s) on an arm. Do not lay cables on the floor but attach them to the desk.
Bedroom: hang bedside tables on the wall, they should also have drawers to store small items. Mount bedside lamps on the wall as well.
