The first sketch for the new project.

The client likes the modern style and light colors. With that in mind, we suggest finishing the main body of the house in several shades of plaster and adding rustication on the bay window for decoration. We would keep the plinth fairly narrow, in graphite-colored stone, and combine it with vertical groupings of planken inserts in places.

A bay window (Erker) — the part of a façade that projects beyond the main plane. It can take various shapes (round, rectangular, polygonal) and span one or more floors. It's carried on cantilever beams; if the support continues down to the foundation, it's already a risalit.

One half of the façade keeps its traditional bay window untouched, while the other half merges the bay with a dormer to form a larger projecting volume with floor-to-ceiling windows. It's a great example of reinventing an existing façade with minimal intervention.
