Learn Building and Planning Law

What Building and Planning Law covers

Building law splits into federal planning law (BauGB, BauNVO) and the building codes of the states. Exams revolve around the building permit, whether a project is permissible under planning law and protection of neighbours.

In Lexxington, Building law is part of public law. The course follows the material the exam regulations set for the compulsory subjects and is split into lessons that build on each other.

Lessons in the course

The German course uses German titles; here they are as they appear in the app.

1. Baurecht
2. Bauleitplanung
3. Zulässigkeit von Vorhaben nach §§ 29 bis 35 BauGB
4. Nachbarschutz und Bauordnungsrecht

Typical exam issues

These issues come up again and again in practice and exam papers. You should spot them while reading the facts and know where they belong in your analysis.

• Projects within a development plan (§ 30 BauGB)
• Built-up areas under § 34 BauGB
• Outlying areas and privileged projects (§ 35 BauGB)
• Neighbour protection and the duty of consideration
• Stop-work and demolition orders

Knowing an issue is not enough. In the exam you must find it in unfamiliar facts, cite the provision and set out the competing views briefly. That is exactly what Lexxington’s cases practise.

Common mistakes

• Spending pages on uncontroversial points and running out of time for the real issue.
• Citing the provision without applying it to the facts.
• Setting out a dispute between views when all of them reach the same result.
• Abandoning the structure because one issue jumps out early.

How Lexxington trains Building law

Understand first: lessons

Each lesson explains one section in short paragraphs. A scale shows exam relevance, a colour gradient shows difficulty. Each part sits behind a card: say it yourself, then reveal, so you know right away what has stuck.

Then apply: cases with statements

A case is a short set of facts with several statements. You decide for each whether it is right, then see the reasoning and the provision. This is retrieval practice: Roediger and Karpicke (2006) showed that testing improves retention far more than rereading.

Keep it: flashcards

Definitions and key rules come as flashcards. The app schedules reviews at growing intervals, right when you begin to forget. Cepeda and colleagues (2006) reviewed hundreds of studies: spaced practice beats massed practice.

Get exam-ready: schemes and timed exams

Exam schemes give you the structure. In the exam simulation you write against the clock and get graded on the 0 to 18 point scale. Lexxi, the AI owl, explains every provision and asks back when you are unsure.

Building law cases do not only appear in subject practice. In the daily session the app mixes them with due and weak questions from other subjects. Whatever you get wrong goes into the error log, and “Weak topics” lets you practise it again on purpose.

Three cases from the course

This is what fact patterns look like in the app (in German, as in the course). Each comes with several statements to assess.

When it comes up in your degree

Building law is usually in the fourth or fifth semester. It stays examinable until the state exam, so it pays not to drop it after the semester exam. Lexxington keeps it fresh with short reviews while you move on to new subjects.

Mixed practice helps. When tasks from different subjects alternate, you learn to recognise the right issue instead of repeating the method from the last chapter. Research calls this interleaving. More on the science
