Design notes

NoteThe house is sized to fit your rooms and covers 55.6% of the plot. Your rules allow up to 70%, so you can make rooms bigger or keep a larger garden.
CheckLiving room faces north and gets little direct sun. Compare the option with living on the other side.
NoteGarage uses 3.10 m of street frontage and sets the front rooms at 5.40 m deep.
NoteSide walls are treated as blank party walls, so every room takes light from the front or back.
NoteA 2.60 × 2.90 m dogleg stair sits in the same place on every floor.
NoteFloor area ratio is 1.11 (total floor area ÷ plot area). Check the maximum your local planning rules allow.
