Space efficiency solutions

KONE Vertical Shaft Optimization is a space-saving elevator design approach that reduces the required pit depth and overhead height for high-speed configurations without compromising safety or performance. It uses sensor-based technology and an optimized safety concept to enable shallower pits and lower headroom. This reduces excavation and structural complexity while freeing up usable space above and below the shaft.

No. KONE space-saving solutions are designed to maintain both safety and performance while reducing shaft dimensions. Sensor-based safety systems and optimized shaft design ensure reliable operation and consistent ride quality, even with reduced pit depth and overhead space.

Space-saving shaft design is available across KONE elevator solutions rather than limited to a single model. These solutions can be applied in both new buildings and existing installations, helping achieve required capacity and people-flow performance without increasing shaft size.

Yes. KONE space-saving solutions are particularly well suited for elevator modernization projects. In full replacement projects, they can increase elevator capacity, improve travel efficiency, and reduce waiting times — helping create a better experience for building users. By reducing the amount of required construction work, they can also lower project costs and shorten elevator downtime, minimizing disruption during modernization.

KONE offers both EN 81-20 and EN 81-21 based solutions.

EN 81-20 solutions, such as Vertical Shaft Optimization and no-headroom solutions with maintenance from the car, have an EU type certificate, enabling wide use in both new and existing buildings.

EN 81-21 solutions, such as reduced pit and headroom solutions with temporary safety devices, have more limited applicability and are primarily intended for existing buildings. In some countries, such as Germany and Switzerland, they may also be used in new buildings, while other countries may not permit these solutions. Please check local regulations for your specific project.

Space-saving elevator design reduces both construction cost and space requirements by optimizing shaft dimensions.

Reduced pit depth lowers excavation and waterproofing needs, while lower overhead simplifies roof construction. This shortens construction time, reduces structural complexity, and frees up valuable space for uses such as rooftop amenities, parking, or storage - helping increase overall building value.

KONE space-saving solutions can support LEED and BREEAM certification by contributing to more efficient use of space, materials, and construction processes. By reducing excavation, structural work, and material use — and enabling additional building features such as green roofs or solar panels — they can help lower a building’s environmental impact across its lifecycle.
