shape and unified at the center, and instead of repeated identical patterns, the architectural plan appoints successively receding and rotated stories. The Y-shaped plan is ideal for residential and hotel usage, with the wings allowing maximum outward views and inward natural light. Viewed from above or from the base, the tips of the Y-shaped plan evoke the onion domes of Islamic architecture.
The Architects With the design and engineering of Burj Khalifa, Skidmore, Owings & Merrill LLP (SOM) joined forces with Dubai based developers Emaar Properties PJSC, to redefine what was possible with supertall buildings. With a portfolio that includes some of the most important architectural accomplishments of the 20th and 21st centuries, including the John Hancock Center and Willis (formerly Sears) Tower, SOM was perfectly placed to carry out this challenging task.
Construction Highlights Burj Khalifa is truly the product of international collaboration; over 60 consultants including 30 on-site contracting companies from around the world were involved in the project. Over 1.59 million cubic ft. (45,000 m3) of concrete, weighing more than 121,254 tons (110,000 metric tons), were used to construct the concrete and steel foundations, which feature 192 piles, buried more than 164 ft. (50 m) deep. Burj Khalifa employs a record-breaking 11.6 million cubic ft.

LEGO® Architecture—then and now There has always been a natural connection between the LEGO® brick and the world of architecture. Fans who build with LEGO elements instinctively develop an interest in the form and function of the structures they create. At the same time, many architects have discovered that LEGO bricks are the perfect way of physically expressing their creative ideas. This connection was confirmed in the early 1960s with the launch of the LEGO ‘Scale Model’ line.
