Last updated: About 1 min read

Changing the floor plan during a condominium renovation allows you to create a space that fits your current lifestyle. This guide explains structural constraints, key points to check in the management rules, and recommended floor plan ideas.

How much freedom do you have to change a condominium floor plan?

The degree of freedom for floor plan changes varies greatly depending on the building structure.

The difference between frame structures and wall structures

Frame structures (supported by columns and beams) allow most interior walls to be removed, offering a high degree of flexibility. Wall structures (supported by walls) have many walls that cannot be removed, which limits floor plan changes.

The renovation scope is limited to the exclusive-use area

Work cannot be done on common areas (such as entrances, structural walls, and floor slabs).

Restrictions under the management rules

In some cases, changing flooring materials to wood flooring or moving wet-area fixtures may also be prohibited. Be sure to check the management rules in advance.

What should you consider first when changing a floor plan?

Clarify your lifestyle vision

Picture specifically how your family will spend time and where people will gather after the renovation, and set clear priorities.

Do not focus too much on the number of rooms

Adding too many rooms can make the space feel cramped. A balance between openness and privacy is important.

Try drawing the traffic flow

If you use a "block plan," which architects also use, to visualize the rough room layout and how people move through the space, you can identify wasted space and inconvenient traffic flow.

  • Adding a loft: If there is enough ceiling height, it can be installed even in a condominium. Suitable for a children's room or hobby space
  • A space centered around an island kitchen: Makes communication with family easier and creates an open feel
  • A gentle glass partition: Creates a cafe-like atmosphere while also dividing the space

Frequently Asked Questions (FAQ)

Q. Can you renovate a rental condominium as well?

As a rule, permission from the owner or landlord is required. In the case of a condominium unit, application to and approval from the management association are required.

Q. How long does a floor plan change take?

As a guideline, allow 1 to 2 months for design and 2 to 4 months for construction. The timeframe varies depending on the scale.

Q. Can the location of wet areas be changed?

It depends on the structure and the management rules, but technically it is often possible if the necessary drainage pipe slope can be secured.
