Why take a laughably small floor plan and divide it further?

Small spaces have to be open plan, really deliberate about negative space to avoid feeling cluttered, and make good use of vertical space.

Another key tell that a penut drafted this is that the house is oriented to the road not the sun, there are no outbuildings, the doors share the same swing space so both end up creating a whole meter of dead space, the bathroom amenities are dodgem car style, dirt will blow straight into the kitchen, loft seems totally wasted.
