pencil tower by Durbach Block Jaggers

Durbach Block Jaggers- an Australian architecture studio, has revealed the design of its super skinny hotel soon to be built at 410 Pitt Street in Sydney. The height of the Tower is around 110 meters, while the width is only 6.4 meter. The Pencil Tower Hotel by Durbach Block Jaggers will stand on a seven-story podium with a lobby, café, lounge, and a spa with a flying balcony on the rooftop. With six suites on each floor, the hotel would contain 173 rooms. Read more about this implausibly narrow Pencil Tower:

It will be Australia's skinniest skyscraper once complete, with a height-to-width ratio of 16:1.

Labelled as a "sky scratcher" by the studio as it is "too thin to really qualify as a skyscraper", the building design has been suggested to planning authorities. Neil Durbach, the architect of the Pencil Tower, designed hotel rooms like a train compartment because of its super compact feature.

According to Durbach Block Jaggers, this will make the skinny skyscraper resemble the arrangement of a column on a base topped with a capital.

Thin Tower With A Podium

The building appears as an arrangement of a column on a base crowned with a capital. The architect has also created the podium to mention the nearby facades at street level. The skyscraper features a modern façade clad in marble and metallic material, and a slender vaulted roof encloses the spa with tiled ceiling.

"An improbably narrow, six-metre-wide site is envisaged for a 100-metre tower in the downtown area of Sydney near its central station," said the studio. "Our proposal embraces this extraordinary attenuated quality, proposing a 'column' tower on a low scale podium."

Design Details

With a height-to-width ratio of 16:1, Pencil Tower Hotel is set to be built in the downtown area of Sydney that has only 6.4-meter-wide street frontage.

Traditional concrete columns and slabs will be used to create six storey podium section. Steel framework, used in the upper floors, will become a part of the lasting structure.

The Tower is constructing between the two existing buildings on Pitt street. Due to the site's limitations, mostly construction of the Tower will take place without the use of cranes.

According to the studio, the crane access can become a challenge above floor six, given the narrow site. The construction team is utilizing the permanent formwork and steel slab forms for walls, which can be easily handled and assembled without a crane.

"In many ways, the building is handmade," said the studio.

The Pencil Tower Hotel, designed by Durbach Block Jaggers in Sydney's Haymarket, combines unique design with a modern style. The firm awarded with the Design Excellence competition, won over other firms like Scott carver, Sisson Architect and SJB, to develop the Tower.

Other Skinny Skyscrapers

There is a tremendous increase in skinny skyscrapers; The Pencil Tower Hotel is one of them. Another narrow tower is Collins House in Melbourne that Bates Smart has designed. It is 184 metres tall and just 11.5 metres wide.

SHoP Architects is also planning to design the skinny Tower -West 57th in New York with a height-to-width ratio of 24:1. It will be the world's skinniest skyscrapers after completion. In New York, several slender towers are under construction; even the city's Skyscraper Museum has created an online tracker to record them.
