A townhouse is a multi-story (two or more) home that has an entrance typically on the street and usually has a small footprint (smaller lot) often a zero lot line (no space between townhome and adjacent building). In California, U.S.A, it is considered to be an architectural style. It could be a condominium in which the owner owns the exterior walls, the "air space" within, and shares ownership in areas common (greenbelts, roadways, mailboxes, or other amenities.) It could be an attached house in which the owner exclusively owns the structure and the land under and immediately adjacent to the building (courtyard, small rear or front patio, etc.).

Townhouses typically offer more square footage in one dwelling and are often popular in highly populated metropolitan areas with close access to transit and business centers.

A townhouse is like a house in that the owner owns both the structure and the land on which it sits; but it is not free-standing, so "the land on which it sits" is limited to the front and back yards. Townhouses are connected to one another in a row, and are usually two or three stories tall. They share many of the characteristics of condominiums.

The Normal House is a small, intentional, co-housing community in the Normal Heights.

Basically a 3 storey terrace or sometimes semi detached, take up less land. Historically a house in town, belonging to someone who also has a country house ,country houses are quite grand in the UK a lot are hotels these days

Well in north america, town houses generally are smaller, connected buildings, generally for housing more people in a small area. They're also generally cheaper to buy/rent, but that can depend where you live.

Generally from my experience, town houses are separated by building to building, but in other countries it can be many attached buildings, but multiple stories to hold each resident, kind of like an apartment.
