A maisonette (複層式) apartment is a unit that spans two floors within an apartment building, offering a house-like living experience. This guide explains the features, pros and cons, and who maisonette apartments suit best.

What Makes a Maisonette?

Unlike a standard single-floor apartment, a maisonette has living space on two separate floors connected by an internal staircase. The entrance is usually on the lower floor, with bedrooms on the upper floor.

Advantages

  • House-like feel: The staircase and two-floor layout give a detached-home atmosphere
  • Clear separation between living and sleeping areas: Lower floor for living/dining, upper floor for bedrooms
  • Better privacy: No neighbors directly above or below (depending on building layout)
  • Often better natural light: Windows on two levels

Disadvantages

  • Stairs can be inconvenient: Carrying laundry and groceries up and down
  • Larger footprint: Usually costs more than a standard single-floor apartment of similar area
  • Cold in winter / hot in summer: Two-floor spaces with stairs can have drafts
  • Smaller for families: Total area may look large but effective living area per floor can be limited

Who Is It Best For?

Maisonette apartments suit people who value privacy, want a house-like atmosphere without the cost of renting a whole house, or work from home and want a clear separation between workspace and living area.

FAQ

Q. Are maisonette apartments more expensive?

Generally yes — rent tends to be 10–20% higher than comparable single-floor units due to the desirable layout and style.

Q. Are maisonettes good for families with children?

The stairs can be a risk for very young children, but for school-age kids the two-floor layout is popular. Check the staircase design for safety.
