The Window Building

This is a prime office building designed for Inmobiliaria Colonial, which is LEED Gold certified and was awarded by the Spanish Office Association for its sustainable and innovative design in 2020.

Based on the pre-existence of a mixed-use office and apartment building on the plot, and after discarding its partial refurbishment due to the compromises it would entail (height between floors or distances between pillars too low for the current needs of flexibility, or inadequate overloads for the current guidelines), its complete demolition is proposed, projecting from scratch a flexible, bright, spacious building with high ceilings and the latest technologies.

The Window Building is a new office building with 11,300 m² of GLA distributed over 8 floors and 115 parking spaces. The building has more than 600 meters of gardens and several terraces distributed over the different floors of the building. For its construction, avant-garde and state-of-the-art materials have been chosen. All these details make The Window a space that invites you to imagine, think and create.

The Window Building’s design offers flexibility to its users, multiple alternatives and the possibility of creating all kinds of spaces. Its floors, with a single line of pillars, are diaphanous, spacious and make the most of natural light. This is achieved by taking the following decisions in the design of the project:

• Use of free spans of 8.50 x 15.50 m achieved by means of post-tensioned slabs.
• Floor-to-ceiling façade modules of 2.70 m wide x up to 3.60 m high.
• The main communications core is moved to the back of the plot, as a strategy to free up office space and the most valued facades.
• The existing building is reduced by one floor to achieve a greater height between floors.
• Transformation of the regulatory corset that forces to maintain the pre-existing volumetry into an opportunity to give value to the forced staggering, turning them into more than 600 meters of gardens and terraces distributed in the different floors of the building.
