Explore how new rooms can connect to an existing house while keeping circulation and approximate dimensions visible.

Lay out bedrooms, bathrooms, stairs, and grouped plumbing for a proposed new level above an existing house.

Test how an existing garage footprint can become living space with light, egress, storage, plumbing, and a connection to the house.

Arrange a primary bedroom, en-suite, walk-in closet, windows, and a short connection to the existing home.

Explore side, rear, or courtyard additions that work with a single-storey ranch footprint.

Plan an addition around half-level stairs, existing entries, and the circulation constraints of a split-level home.

Lay out finished rooms while preserving stairs, mechanical space, storage, egress, and plumbing relationships.

Test an attic layout with stairs, head-height zones, dormers, storage, a bedroom, and a compact bathroom.

Plan a glazed addition with doors, window walls, furniture, and a clear connection to the existing living space.

Record the rooms, openings, fixtures, stairs, and dimensions that exist before proposed work begins.

Create a clear house planning layout from rooms, dimensions, openings, fixtures, and circulation described in one brief.
