Calculating Usable Area and Living Space Correctly for Houses and Apartments in Hamburg

A person draws on architectural blueprints with a pencil, using a ruler on a desk with a laptop and a black mug nearby.

One of the most important details in a real estate listing is the size specification of the living area or usable space. This information helps potential buyers understand how much space a house or apartment offers and whether the price per square meter positions the property above or below the average market level. However, there are fundamental differences between the professional definitions of living space and usable area—differences that not every property owner is familiar with. Engel & Völkers Hamburg aims to explain the basics of these area calculations in this article, so you can be well prepared for selling your property in Hamburg Wilhelmsburg or the surrounding districts.

First step: Calculating the floor area of your property in Hamburg

To determine the living or usable area, you first need to calculate the basic floor area. The calculation is based on the guidelines of the DIN standard 277, which governs the measurement of floor areas and volumes. The simplest form of floor area measurement defined by this standard is the gross floor area, which includes the total footprint of the building across all floors. When you subtract all inaccessible areas—such as walls, support beams, cladding, and similar structures—you get the net room area, which measures the basically accessible space within the property in Hamburg Wilhelmsburg.

So far, this term alone does not have a specific practical application and would offer limited insight when selling a house or apartment. It is refined by the seven different categories of usable space defined in DIN standard 277. In the next section, Engel & Völkers real estate agents explain how this classification helps differentiate between living area and usable space for the sale of your property.

The living area of your house or apartment as one of seven categories of usable space

When discussing the distinction between living area and usable space in a property in Hamburg Wilhelmsburg, the key question for a clear classification is: Which parts of the net room area are suitable for living and staying, and which parts can only be used otherwise and therefore fall into one of the other six categories?

To be classified as living area according to DIN 277, the space must meet several requirements. Proper interior finishing and basic heating capability are fundamental prerequisites, as is a minimum ceiling height of two meters. If the ceiling height is between one and two meters, or if the space is an outdoor area such as a terrace or balcony, only 50% of this area is counted towards the living area.

However, it is important to note that these are minimum standards and are often applied more generously in practice. Additionally, they partly differ from the requirements of the German Federal Living Space Ordinance (Wohnflächenverordnung) of 2004. For this reason, our Engel & Völkers real estate team recommends specifying the relevant reference source when selling your property to ensure clarity and avoid misunderstandings.

Which other types of usable space are calculated alongside the living area of a property?

If certain parts of your house or apartment in Hamburg Wilhelmsburg cannot be classified as living area, they can be assigned to other categories of usable space. These include:

Office spaces
Production areas & laboratories
Medical practice rooms
Retail spaces
Storage rooms, attics, basements
Other usable space

Additionally, there are areas that neither fall under living nor usable space. These include traffic areas such as elevators or emergency exits, as well as technical functional spaces like boiler or heating rooms.
