Owl Tower

Owl Tower is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Owl Tower rather than just read about it. In short: The Owl Tower (アウルタワー) is a residential building in the Toshima special ward of Tokyo, Japan. Completed in January 2011, it stands at 189.2 m (621 ft) tall, with the top floor located at 182.8 m (600 ft).

Key takeaways

Owl Tower belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Owl Tower to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Owl Tower from memory before moving on to harder problems.

Reference excerpt

The Owl Tower (アウルタワー) is a residential building in the Toshima special ward of Tokyo, Japan. Completed in January 2011, it stands at 189.2 m (621 ft) tall, with the top floor located at 182.8 m (600 ft). It is the 38th tallest building in Tokyo and the 55th tallest building in Japan.

Overview The Owl Tower was constructed as a response to the issues regarding the utilization of already existing buildings, namely to specialize skyscrapers in the area, make use of available land effectively, prevent a mixed-use of buildings, and also to encourage people to live in the Ikebukuro district. Its name references the mascot of the district. The Owl Tower is located near the Air Rise Tower, and close to the Higashi-Ikebukuro Station, to which it is directly connected by an underground promenade, and the Sunshine City complex with the Sunshine 60 skyscraper, the tallest building in Tokyo from 1978 to 1991. The skyscraper was built on a lot with an area of 5,801.39 square metres (62,445.6 sq ft), 2,938.03 square metres (31,624.7 sq ft) of which is occupied by the building itself. Reinforced concrete, steel, and glass was used during its construction, which costed approximately 30 billion yen. The building was designed and constructed by the Taisei Corporation. The city planning decision to build the Owl Tower was made in May 2004, and the planning permission was given in January 2006. The construction began in October 2007, and was completed in January 2011. In late March of the same year, the building was ready to be moved in. Although the Owl Tower is mainly a residential building, some storeys are meant for office or commercial use. Stores are located in the 1st basement and on the 1st floor, while offices can be found from the 2nd to the 6th floor. Apartments are situated on the remaining floors, up to the 52nd. There are 11 elevators in the skyscraper. The total floor space of the building equals roughly 79,200 square metres (853,000 sq ft). There are approximately 608 units, 473 of which are for residential purposes, and 135 of which are for non-residential purposes, with the rest of the rooms including a theater room, a fitness room, and a sky lounge, among others. 344 parking spaces are contained within the Owl Tower.

Worked examples

Example 1 — a first encounter with Owl Tower

Start with the simplest possible case. Write down what Owl Tower claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Owl Tower before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Owl Tower ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Owl Tower

In research: Owl Tower appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Owl Tower in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Owl Tower is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 2011, Buildings and structures in Toshima, Residential skyscrapers in Tokyo, so understanding it makes those chapters shorter.
In everyday life: Look for Owl Tower outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Owl Tower in simple terms?

Why does Owl Tower matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Owl Tower?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
