How it works

How the House Map Maker works

Start from the plot

The boundary comes first, then the house

A house map is decided by the plot before it is decided by the rooms. Draw the plot outline to its real dimensions and mark which edge faces the road, because that sets the entry, the parking and which rooms can take windows. Only then place the built footprint inside it. Working the other way round, arranging rooms first and fitting them to the plot afterwards, is what produces a layout that has to be redrawn once the setbacks are applied.

  • Draw the plot to its actual dimensions before anything else.
  • Mark the road-facing edge, since it fixes entry and parking.
  • Apply the required setbacks and treat the remainder as buildable.
  • Place the footprint inside that remainder, not across it.
Ground floor

Separate the public rooms from the private ones

On the ground floor the entry, drawing room and any guest space form the public half, while bedrooms, kitchen and service areas form the private half. Keeping a visitor from walking through the private half to reach the drawing room is most of what makes a house map feel right to live in. A short entry passage, or simply turning the drawing room to face the entry, usually solves it without adding area.

  • Give visitors a route to the drawing room that avoids bedrooms.
  • Keep the kitchen reachable from the dining area without crossing it.
  • Put the service area, wash and storage on one side together.
  • Check the stair position works for both floors before fixing it.
Upper floor

The stair position decides the floor above

Once the staircase is placed, the upper floor is largely determined: the landing arrives somewhere, and every bedroom has to hang off it. Draw the upper floor as a second level over the same plot so the stair, the load-bearing walls and the shafts line up between the two. Bathrooms and kitchens stacked above one another keep the plumbing runs short, which is easier to arrange while it is still a drawing.

  • Draw the upper floor over the ground floor so walls align.
  • Stack bathrooms above bathrooms to keep plumbing runs short.
  • Check the landing reaches every bedroom without a long corridor.
  • Keep the stair a consistent width on both floors.
