Duplex, Townhouse or Apartment? Comparing Attached Housing

Duplex, Townhouse or Apartment? Comparing Attached Housing

Domira Team August 11, 2025 2 min read

Attached housing types differ in privacy, maintenance responsibility and how easily they sell.

Between a detached villa and an apartment sit several attached housing types that suit households wanting more space than a flat and less responsibility than a villa. They differ in ways that matter daily.

Duplex or townhouse at a glance

A multi-storey home sharing one or two walls with neighbours, usually with its own entrance and often a small outdoor area.

Apartment at a glance

A single level unit within a building, with shared maintenance of the structure and common systems.

Privacy

Duplex or townhouse: Generally better, with a private entrance and fewer shared surfaces, though party walls still transmit sound.

Apartment: More shared surfaces, including floors and ceilings, which is where most complaints originate.

Maintenance responsibility

Duplex or townhouse: Yours, including the roof and external envelope, which are significant items.

Apartment: Shared through the service charge, which is predictable but outside your control.

Outdoor space

Duplex or townhouse: Usually some private outdoor area, even if modest.

Apartment: Balcony at most, with any garden being communal.

Accessibility

Duplex or townhouse: Stairs are inherent to the type, which affects elderly residents and long-term suitability.

Apartment: Single level, with lift access in most buildings.

Resale market

Duplex or townhouse: Family buyers, generally a smaller pool than for apartments.

Apartment: Broad, including investors, which supports liquidity.

When duplex or townhouse wins

  • You want the vertical arrangement and private entrance of a house.
  • A small outdoor area matters to the household.
  • You accept maintaining the building yourself.
  • Shared walls are acceptable given the layout and construction.

When apartment wins

  • Single level living suits the household, including elderly members.
  • Shared maintenance is preferable to individual responsibility.
  • Building amenities and security have value to you.
  • Lower entry price allows a better location.

How to decide

Choose a duplex or townhouse where private entrance, outdoor space and the feeling of a house matter and you accept the maintenance. Choose an apartment where single level living, shared maintenance and liquidity matter more.

For attached housing, inspect the party wall construction specifically and visit at a time when neighbours are home. Sound transmission through party walls is the most common complaint in this housing type and the hardest to remedy afterwards.

If you are buying a finished property, Domira can inspect it, verify the documentation and price the findings with you before you commit.

Frequently Asked Questions

How do I assess sound transmission before buying?

Visit when neighbours are present, listen against the party wall, and ask the seller and neighbours directly. Where possible, establish the wall construction, since a single masonry wall performs very differently from a properly detailed separating wall.

Who maintains shared elements in a townhouse development?

It depends on the development's arrangements, which may include a management company for common areas while individual owners maintain their own buildings. Establish this before buying, since the arrangements vary and affect both cost and responsibility.

Do duplexes hold value as well as villas?

They serve a different buyer, and value depends primarily on location and condition rather than on type. What matters for resale is that the unit suits its market: a well-located duplex in an area where families want that format performs well.
