When choosing a condominium, people often focus on location and layout, but the type of shared corridor has a major impact on day-to-day comfort. Outer corridors and inner corridors each come with different advantages and disadvantages, so it is important to choose the option that fits your lifestyle.

What is the difference between an outer corridor and an inner corridor?

An outer corridor faces the outside of the building, while an inner corridor is located inside the building.

Characteristics of outer corridors

They are commonly used in older condominium buildings, with all units arranged in the same direction.

Characteristics of inner corridors

They are often seen in tower condominiums and luxury residences, with units on both sides of the corridor in a hotel-like layout. A premium finish using carpet or marble is a typical feature.

What are the advantages of an outer corridor?

It offers strengths in disaster preparedness, ventilation, and cost efficiency.

  • Securing an evacuation route:Fire truck ladders can reach it more easily, and smoke is less likely to build up
  • Sunlight and ventilation:South-facing layouts are common, making ventilation easier
  • Lower management fees:No air-conditioning equipment is required, which helps reduce construction and maintenance costs

What are the disadvantages of an outer corridor?

  • Rain, snow, and debris can enter more easily
  • Entrance doors and handrails are more likely to deteriorate due to UV exposure
  • It is hot in summer and cold in winter
  • Footsteps echo more easily, and privacy is lower

What are the advantages of an inner corridor?

It performs well in comfort, privacy, and a sense of luxury.

  • You can move around comfortably without being affected by the weather
  • Climate control maintains a comfortable temperature throughout the year
  • Privacy is better protected because people coming and going are not visible from outside
  • Hotel-like luxury feel

What are the disadvantages of an inner corridor?

  • Management fees are higher (electricity costs for air conditioning and lighting)
  • Ventilation can easily become insufficient
  • There is a risk of smoke accumulation during a disaster
