The 3-frontage house is an excellent compromise between the economy of semi-detached and the freedom of 4 frontages.

1. Configuration

Semi-detached on one side, free on the other three. See buying a new-build house.

2. Energy performance

The party wall limits heat loss. See EPC new-construction.

3. Local market

See new-build house Walloon Brabant.

Questions on the 3-frontage new-build

Advantages of 3 vs 4 frontages?
Narrower plot (so cheaper), one wall without heat loss, slightly lower construction cost. Disadvantage: one fewer view.
What minimum plot for 3 frontages?
From 180-220 m² depending on plot depth and planning rules.
