Engineering Challenges & Solutions
The Asteroid required a sophisticated foundation approach to support its impressive 80-meter height and unique structural design. Theodoros was responsible for the analysis and design of the raft foundation on piles system, ensuring optimal load distribution and structural stability for this high-rise construction.
Engineering challenges addressed:
-
Accommodating high vertical loads from the 16-floor structure
-
Managing lateral forces from wind and seismic activity
-
Ensuring stable foundation for innovative raking columns
-
Coordinating with complex basement layouts and parking requirements
-
Geotechnical analysis and soil-structure interaction
-
Pile load capacity and settlement calculations
The solution involved comprehensive geotechnical analysis, pile load testing, and advanced structural modeling to create a foundation system capable of supporting this iconic high-rise safely and efficiently. The raft foundation distributes loads evenly across the pile group while providing the necessary stiffness for the superstructure above.

The building's primary structural system consists of a reinforced concrete frame spanning 2 basement levels and 16 floors above ground. This complex structure required meticulous analysis and design to accommodate the building's unique architectural features.
Engineering challenges:
-
Design of slender concrete elements for maximum interior space
-
Integration with curved glass facade requirements
-
Coordination between structural and architectural geometries
-
Ensuring structural continuity through complex floor transitions
-
Managing construction sequencing for tall concrete construction
Advanced concrete mix designs, detailed reinforcement layouts, and precise construction tolerances were essential to achieve both structural performance and architectural vision.
-
The Asteroid's most distinctive feature is its raking columns positioned at the North and South elevations. These inclined structural elements create the building's signature curved surfaces where the glass curtain walls are seamlessly integrated.
Technical challenges addressed:
-
Complex geometric analysis for non-vertical load paths
-
Advanced structural modeling for inclined column behavior
-
Integration with horizontal floor systems and vertical cores
-
Accommodation of building services within curved geometry
-
Coordination with curtain wall attachment systems
-
Wind load distribution through angled structural elements
This innovative design element required advanced structural analysis and creative problem-solving to achieve both architectural vision and structural integrity. The raking columns represent a significant engineering achievement in Cyprus's construction industry.
-
Building stability is ensured through a strategically positioned reinforced concrete core at the center of the structure. This core system provides lateral stability against wind loads and seismic forces, crucial for a building of this height in the Eastern Mediterranean region.
Core design considerations:
-
Seismic design requirements for Cyprus location
-
Wind load resistance for 80-meter height
-
Integration with elevator and stair systems
-
Coordination with mechanical and electrical services
-
Connection details with perimeter raking columns
-
Progressive collapse prevention measures
The central core acts as the building's structural backbone, working in harmony with the perimeter raking columns to create a robust and efficient lateral force resistance system.
-
Beyond the concrete framework, several key structural steel components were designed to complement the overall structural system. These elements demonstrate the successful integration of mixed construction materials.
Steel elements designed:
-
North Veranda: Sophisticated steel structure extending usable space
-
East Lobby: Structural steel framework supporting main entrance area
-
Roof Level Canopy: Elegant steel canopy providing functional and aesthetic value
-
Connection systems between steel and concrete elements
-
Expansion joint details for thermal movement
-
Corrosion protection systems for Mediterranean climate
The steel elements required careful coordination with the concrete structure, ensuring proper load transfer, thermal compatibility, and long-term durability in the coastal environment.
