How is the building envelope?
Do you have to build so close to the street?
Is that a main or a side street?
Questions, questions, questions!
Sorry, but the orientation of the house is a no-go for me... and I would explore every option to get some sun into the living space. House further back, utility room facing north (damn the long supply lines, you only die once), bedrooms to the east, kids' wing with shower toilet, parents' area at the back with a cleverly placed walk-in closet as access to the bedroom (so there’s no long hallway ;))
Nice terrace to the southwest, show off the best side! :) (if necessary, a hedge will do) and entrance to the east.
This is too superficial for me, tips can only be made concrete with information, information, information!
And the measurements have to be right.
