Layouts and floor areas

Usable area (užitná plocha)

In Czech: Užitná plocha

Usable area (užitná plocha) is the area of all spaces in a flat or house that can be used, including rooms and ancillary spaces such as bathroom, hallway or storage. What is included varies.

Also called: užitná plocha, užitková plocha, usable floor space

What it means

Usable area, in Czech užitná plocha, is the area of the spaces that are actually used: habitable rooms plus ancillary spaces such as the kitchen, bathroom, toilet, hallway, walk-in wardrobe or storage room. It is therefore usually larger than living area (obytná plocha), which covers rooms only.

The term is used for flats and houses alike. For a family house it may include the basement, garage, utility room or attic. There is no single definition that all adverts follow, and in everyday Czech you will also see the variant užitková plocha for the same thing.

How it works in the Czech Republic

For a flat, the usable area in an advert often matches the floor area. It differs when the advertiser adds a cellar, balcony or terrace. For a house it can include every floor, unheated spaces too, so the figure may be much higher than the space you actually live in.

Attic and basement space deserve a separate look. Part of an attic under a low sloping ceiling is only good for storage, and a basement without windows may not be suitable for living. If such spaces are inside the usable area, the headline number does not tell you how many square metres are habitable.

The figure is usually based on project documentation, a building passport (pasport stavby), an expert valuation or the seller's own measurement. Authorities, banks and insurers may determine areas by their own rules for their purposes, so numbers in different documents can differ.

Practical example

For example, a family house is advertised with 180 m² of usable area (an illustrative figure). The breakdown shows that the number includes the garage, a basement cellar and an unheated loft. The rooms, kitchen and bathrooms on the ground and first floor make up only part of it, and that part is what you should compare with other houses.

What to watch out for

  • Ask for a breakdown of usable area by floor and by room.
  • Find out whether a garage, cellar, loft or utility room is included.
  • For attics, ask from what ceiling height the area was counted.
  • When comparing houses, compare the same kind of area, not usable area for one and living area for the other.

Frequently asked questions

What is the difference between usable area and living area?

Living area covers only the rooms you live in; usable area adds ancillary spaces such as the bathroom, hallway or storage. Usable area is therefore normally larger.

Are užitná plocha and užitková plocha the same?

In everyday use, yes; both refer to the same figure. What matters more is what the advertiser counted in it.

Is a garage included in usable area?

Sometimes, especially for family houses. Ask, because a built-in garage can push the figure up considerably.

  • Floor area (podlahová plocha)Floor area (podlahová plocha) is the floor surface of the rooms of a flat or house, measured inside between the walls. What advertisers include varies, so always ask how it was measured.
  • Living area (obytná plocha)Living area (obytná plocha) is the area of the rooms used for living, such as the living room and bedrooms, sometimes also the kitchen. Bathrooms, hallways and storage are usually left out.
  • Total area (celková plocha)Total area (celková plocha) is the headline size figure in a Czech listing. Depending on the advertiser it may cover only the flat or also a balcony, terrace, cellar or front garden.
  • Built-up area (zastavěná plocha)Built-up area (zastavěná plocha) is the part of a plot covered by a building, its footprint measured along the outside walls. It is used for houses and land and says nothing about indoor living space.
  • Family house (rodinný dům)A family house (rodinný dům) is a building intended mainly for one or a few households, either detached or attached to neighbouring houses. It is usually sold together with the land, of which the building is legally a part.
