Hansahochhaus

Hansahochhaus 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 Hansahochhaus rather than just read about it. In short: The Hansahochhaus is a skyscraper in the Neustadt-Nord quarter of north-central Cologne. When constructed in 1924-25 it was the city's first skyscraper, and one of the first skyscrapers in Germany.

Key takeaways

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

Reference excerpt

The Hansahochhaus is a skyscraper in the Neustadt-Nord quarter of north-central Cologne. When constructed in 1924-25 it was the city's first skyscraper, and one of the first skyscrapers in Germany. It was designed as an office building in the Expressionist style by the local architect, Jacob Koerfer. It was constructed in just 135 working days, which was considered less than the time taken to erect comparable buildings in the United States where skyscrapers were already becoming mainstream by the 1920s, but construction of the Hansahochhaus was subject to interruptions so the total construction period stretched over 15 months. With 17 floors and a total height of 65 meters, for a brief period following its construction the Hansahochhaus was Europe's tallest building. It is currently protected under historic monument legislation.

Worked examples

Example 1 — a first encounter with Hansahochhaus

Start with the simplest possible case. Write down what Hansahochhaus 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 Hansahochhaus 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 Hansahochhaus 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 Hansahochhaus

In research: Hansahochhaus 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 Hansahochhaus 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: Hansahochhaus is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1924 establishments in Germany, 20th-century architecture in Germany, Buildings and structures completed in 1924, so understanding it makes those chapters shorter.
In everyday life: Look for Hansahochhaus 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 Hansahochhaus in simple terms?

The Hansahochhaus is a skyscraper in the Neustadt-Nord quarter of north-central Cologne. When constructed in 1924-25 it was the city's first skyscraper, and one of the first skyscrapers in Germany.

Why does Hansahochhaus 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 Hansahochhaus?

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.
