The London Eye stands as an iconic feat of modern engineering and architectural innovation, symbolizing the transformation of London’s skyline in the early 21st century. The design of the London Eye was inspired by the idea of a "flight" and provided visitors with a unique perspective on the city. Explore its striking design concept, the key figures and engineers behind its construction, the structural ingenuity that enables its rotation, and the distinctive features of its exterior and passenger capsules.
The London Eye’s architecture reflects modern structural expressionism, marked by its cantilevered design and visible engineering elements. Inspired by the form of a bicycle wheel, the structure uses tensioned steel cables and an A-frame support to achieve balance and stability without a central axle. This minimalist and functional approach emphasizes lightness, transparency, and open views, aligning with the late-20th-century focus on blending form with utility. Materials like glass and steel were chosen to create an airy, futuristic feel, while the external mounting of the 32 capsules allows for uninterrupted views.
Several key figures and teams played a pivotal role in bringing the London Eye’s architectural vision to life:
The husband-and-wife architect duo who conceived and designed the London Eye. Their vision was to create a modern landmark to mark the millennium, combining public space with engineering innovation.
The renowned engineering firm is responsible for the structural design. Arup’s team developed the wheel’s unique cantilevered form and managed complex calculations for stability and rotation.
A Dutch steelwork specialist company that fabricated the main steel structure. Hollandia’s precision engineering was crucial for the wheel’s massive rim and tensioned spoke system.
A French company known for cable transport systems, Poma designed and built the 32 glass capsules, each mounted externally to maximize views and enhance the riding experience.
These UK-based construction firms oversaw on-site assembly, including the floating platform technique used to build the wheel horizontally before it was raised upright.
The original sponsor and project backer, British Airways, helped fund and promote the project, facilitating public support and visibility ahead of its official opening in 2000.
The London Eye is a cantilevered observation wheel supported by an A-frame on one side, with no symmetrical support on the opposite side—a structural rarity for wheels of this scale.
Standing 135 metres tall, it consists of a central hub and spindle from which 64 tensioned steel cables radiate outward, forming a massive spoked wheel. The rim is made of tubular steel sections, bolted together with high precision. Thirty-two sealed glass capsules are mounted externally on the rim using motorised rotating mounts, allowing them to stay level as the wheel turns. The entire structure is anchored to a reinforced concrete foundation on the South Bank of the River Thames.
The London Eye’s most striking feature is its 135-metre-tall cantilevered wheel, designed to resemble a bicycle wheel. Supported by an A-frame only on one side, it uses 64 tensioned steel cables radiating from the hub to the rim, giving the structure both strength and visual lightness. The rim, made of tubular steel sections, was fabricated with high precision to support the capsules and ensure smooth rotation.
There are 32 sealed, egg-shaped capsules mounted externally to the rim, allowing for uninterrupted 360° views. Made from glass and lightweight materials, each capsule is climate-controlled and equipped with stabilising motors to keep it level as the wheel turns. The design reflects a blend of functionality and transparency, enhancing both safety and the viewing experience.
Fitted with a programmable LED lighting system, the London Eye transforms after sunset into a vibrant landmark. It regularly lights up to mark national holidays, charitable events, and cultural celebrations. The sleek, white-painted structure reflects ambient light beautifully, making it a centrepiece of London’s nighttime skyline.
The boarding area sits along the South Bank and includes a sleek steel and glass platform that rotates slowly with the wheel, allowing passengers to embark and disembark without stopping the motion. The wheel’s A-frame support and foundation are anchored deep into the ground and reinforced with concrete, ensuring stability while maintaining a minimal visual footprint on the riverside.
Each of the 32 glass capsules offers a sleek, modern interior designed for comfort and panoramic viewing. Spacious enough to hold up to 25 people, the capsules are climate-controlled and fitted with bench seating, though most visitors prefer to stand and move around to take in 360° views. The glass panels are curved to reduce reflection and glare, enhancing photography and sightseeing.
Designed with inclusivity in mind, the London Eye offers step-free access and dedicated spaces within the capsules for wheelchair users. The slow rotation allows easy boarding and disembarking without stopping the wheel. Inside, the open-plan layout ensures unobstructed views for all passengers, and subtle lighting creates a calm ambience during night rides, aligning with the capsule's clean, futuristic design.
The interior of the boarding terminal is designed with functionality and flow in mind. Visitors move through a modern, glass-lined space with minimal barriers, guided by clear signage and gentle ramps. Audio-visual displays offer an introduction to the experience, while the rotating boarding platform, aligned with the wheel’s pace, ensures continuous movement, reinforcing the seamless design of the overall structure.

The London Eye's design is notable for its unsupported structure, which rotates around a central hub using a system of cables and a floating axis. This structure allows visitors to experience a 'hovering' sensation over London with clear views in all directions.
The design was inspired by a bicycle wheel—light, balanced, and transparent—to offer uninterrupted city views.
The London Eye is the fourth tallest structure in London and the world's tallest cantilevered observation wheel.
While not the tallest overall, the London Eye holds the title of the world's tallest cantilevered observation wheel.
While the Eye itself doesn’t have specific eco-friendly design elements, it does employ efficient energy systems. The entire wheel is powered by electric motors designed for energy efficiency, minimizing its environmental impact.
Yes, the London Eye has received numerous awards for engineering and design excellence, including the 2000 RIBA National Award and the Millennium Product designation by the Design Council.
