Metrohan Building

Metrohan Building 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 Metrohan Building rather than just read about it. In short: The Metrohan Building (Turkish: Metrohan Binası) is a 7-story office building in Beyoğlu, Istanbul. The building was built between 1912 and 1914.

Key takeaways

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

Reference excerpt

The Metrohan Building (Turkish: Metrohan Binası) is a 7-story office building in Beyoğlu, Istanbul. The building was built between 1912 and 1914. The ground floor of the building contains the Beyoğlu Tünel station, which is the northern terminus of the historic 573 m (1,880 ft) long funicular railway. The building gets its name from the railway itself; as Metro Han can be translated to Metro House or Metro Building.

History When Beyoğlu station was under construction between 1871 and 1874, plans to construct a 5-story hotel building above the station were drawn out by chief engineer of the project, Eugène-Henri Gavand. However, when Gavand's shares in the railway were bought out, his plans for a hotel were also scrapped. The ground floor of the Metrohan building was the original Beyoğlu station structure, which opened in 1875. The original structure consisted of a wooden A-frame roof on top of the ground floor stone structure that exists today. In 1911, a Belgium company SOFINA bought the operating rights of the railway and needed a central office in Istanbul, known at the time as Constantinople. Plans to build a 6-story office building on top of Beyoğlu station were drawn up in Charleroi, Belgium by Turkish-Armenian architect Mikayel Nurican and construction began in 1912. The original office building consisted of 4 floors (including the ground floor) with a smaller 2-story tower at the top. The building was completed in 1914 and became the headquarters of Tünel operations. In 1928, the 2-story tower was expanded as 2 extra floors and a 7th floor was constructed on top, bringing the building to its current height and shape. Istanbul Elektrik, Tramvay ve Tünel İşletmeleri (I.E.T.T.) bought the Tünel railway as well as the Metrohan building and began using it as their own general headquarters. IETT kept their headquarters in the building until 1983, when they moved to a newer building on top of Karaköy station. The building is currently undergoing restoration by the Istanbul municipal government to be repurposed into a public exhibition space and library.

Worked examples

Example 1 — a first encounter with Metrohan Building

Start with the simplest possible case. Write down what Metrohan Building 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 Metrohan Building 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 Metrohan Building 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 Metrohan Building

In research: Metrohan Building 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 Metrohan Building 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: Metrohan Building is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1914, Buildings and structures in Beyoğlu, Office buildings in Turkey, so understanding it makes those chapters shorter.
In everyday life: Look for Metrohan Building 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.
