The Window Building

It 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 rehabilitation due to the compromises it would entail (height between slabs or distances between pillars insufficient for the current needs of flexibility, or inadequate overloads for the current guidelines), its complete demolition is proposed, designing from scratch a flexible, bright, spacious building with high ceilings and the latest technologies.

The Window Building is a new 11,300 sqm GLA office building distributed over 8 floors with 115 parking spaces. The building has more than 600 meters of gardens and several terraces distributed in 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 right decisions in the conception of the project:

• Use of free spans of 8.50 x 15.50 m achieved by means of post-tensioned slabs.
• Floor-to-ceiling facade modules 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 building is reduced by one floor with respect to the pre-existing building in order 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.
