When someone says "skyscraper", the imagery one gets is of a concrete or glass building shooting up hundreds of feet into the sky. Now, imagine the same building with one key difference - it is made of wood.

For a housing design competition in Stockholm, architect C. F. Møller, architect Dinell Johansson and consultant Tyréns have designed a building that has been shortlisted for the finals. The design is a vision of the future and considers sustainable, cheaper living and construction costs, reports Dezeen.

The renderings of the building look very interesting. If built, the structure will be a 34-story tower that will be higher than the nine-story Murray Grove Tower in London and the proposed 20-floor structure in Vancouver. The structure will have wooden doors, pillars and beams that will be visible through the glass walls. The building will also have amenities like rain water harvesting, solar paneled roofs, a café, a childcare facility, a fitness center and a communal winter garden.

The architects say that this is a one-of-a-kind project that hasn't been taken on before. Commenting on the project, Møller said:

 "The main reason it hasn't been done before is that concrete and steel have a big part of the market. But now the building industry has started taking responsibility for the environment. Construction accounts for around 30-40 percent of CO2 produced in the world globally and if you look at the CO2 released in the production of wood it is a lot better than steel or concrete."

This project is another example of the increasing trend of constructing green buildings, which offer sustainable and healthy operational facilities. These structures focus on efficient energy consumption while preserving and protecting the surrounding environment. Recently, Green buildings have become a fad in the real estate industry.
