For the architect

The bedroom is only for relaxing, sleeping, and a bit of play for the child in the evening - gentle, Mediterranean or wabi sabi style.

Bedroom lighting: layered, glare-free, no ceiling light, two-way switches on both sides of the bed head - turn off the light without leaving the bed.

One person sleeps while the other can still read or go to the bathroom without disturbing them.

Bedroom furniture (bed, chair if any) from Hè Studio - the architect designs to match.

A socket at the bed head for charging; a socket at the dressing table (existing or later) for the hair dryer.

A secondary bedroom may need no design, or limit built-ins so it can be re-designed later - it should not be designed specifically for one age. The ground-floor room: when built it could be a study but later a bedroom - so electrical equipment (lights, sockets) and water must be planned for in advance; later only loose furniture needs to be bought as replacement.
