The topic briefly and concisely
A comprehensive evaluation is the first step to recognizing the often underestimated financial potential of unused land; the prices for building land in Germany more than doubled between 2010 and 2020.
The development opportunities for unused plots are diverse and range from selling to construction to leasing; just by densifying, 625,000 apartments could be created on plots from the 1950s/60s.
Legal frameworks such as the Building Code (e.g., building requirement) and the property tax C, which will be possible from 2025, significantly influence the development potential and require early clarification with the municipality.
If a plot of land lies fallow, it often incurs costs instead of generating income. But what if this unused plot holds enormous potential? Given rising property prices – they doubled in Germany alone from 2010 to 2020 – and the ongoing demand for residential and commercial spaces, now is the right time to think about activating such areas. This article highlights how you can identify, assess, and successfully develop the potential of unused land to benefit from it in the long term. We demonstrate specific steps and strategies for you.
The essential points: Unused land potential
Before we delve deeper into the topic, here are the key insights for you:
Valuation is crucial: A professional property valuation forms the basis for all subsequent decisions and reveals the true potential. The land value, updated every two years, often serves as an initial guideline.
Explore development possibilities: From selling to building to leasing – the options are varied. Through densification alone, approximately 625,000 homes could be created in Germany on land from the 1950s and 1960s.
Understand legal frameworks: Construction laws and local regulations (e.g. development mandate according to § 176 BauGB) significantly influence the development potential.
Weigh costs and benefits: Every development strategy comes with specific costs and investment opportunities. Undeveloped land incurs ongoing expenses such as property tax and insurance.
Take a long-term perspective: The value development of properties is often a long-term process. Those who acquire building land and hold it for over ten years can often realize sales profits tax-free.
Careful analysis of these points helps you unlock the hidden potential of your property.
Site Analysis: Precisely determine the value of your unused property
Before taking concrete action, a detailed site analysis is essential. Ask yourself: Where exactly is the unused property located and what potential does it hold? The location is one of the most crucial factors for value development. Average land prices in Germany were around 226 euros per square metre in the second quarter of 2024, but they can vary greatly. In metropolitan areas like Munich, prices can even reach 2,900 €/m².
Examine the infrastructure: How is the connectivity to transport routes, schools, shopping facilities and medical services? Good infrastructure significantly increases the value. The layout and size of the property also play a role. A look at the standard land values of your community, which are usually updated every two years, provides an initial orientation. Many owners are surprised by the development potential that emerges after a thorough analysis. Remember that even an apparently unattractive property can gain value through clever planning. Understanding these factors is the first step towards unlocking dormant values.
Development options: What possibilities do you have for your property?
Once you have assessed the value of your property, it’s time to look into development possibilities. Which strategy best aligns with your goals and the potential of underutilised land? The options are varied, ranging from outright sale to long-term development. Selling can quickly provide liquidity, especially in high-demand areas where land prices have risen by almost 90% from 2013 to 2023.
You should consider the following main options:
Sale: The fastest way to release capital. A thorough market analysis is crucial for this.
Development: Construction of residential or commercial properties for rent or sale. This can maximise returns but requires higher initial investments.
Subdivision: Larger plots can often be divided and sold or developed individually, potentially increasing overall returns.
Leasing: Long-term income through leasing to farmers, businesses (e.g., for solar parks), or other uses.
Leasehold: You remain the landowner and grant leasehold rights, generating regular ground rent.
The decision for an option should be based on data. An Auctoa evaluation or a conversation with our ImmoGPT can help you understand the financial implications of each option and identify the strategy that suits you best. The complexity of sale or development decisions requires a solid foundation.
Overcome Legal Challenges: BauGB, Grundsteuer C, and Municipal Requirements
The legal framework is a key aspect in activating unused properties. Are you aware of the regulations relevant to your property? The Building Code (BauGB) forms the basis. In particular, the building obligation under § 176 BauGB can oblige owners to develop their property within a certain period, to counteract, for instance, the housing shortage. Municipalities can order this to close building gaps or to relieve infrastructure.
From 2025, the new property tax C can also be levied on buildable but undeveloped properties. This is intended to curb speculation and create incentives for development. Find out early from your local authority about development plans and possible conditions. Not every property can be developed at will. Therefore, a building law assessment is essential. Collaboration with experts can help avoid pitfalls and expedite the process. This way, you ensure that your project stands on a solid legal foundation.
Value enhancement through active measures: From development to upgrading
How can you actively increase the value of your undeveloped land before you sell or develop it? Often, there is significant potential lying dormant. Developing a plot, meaning connecting it to public networks like electricity and water, can already significantly increase the value, but also costs between 7,000 and 10,000 euros. If a plot is already developed, it indicates readiness for construction and saves the buyer time and costs.
Additional value-enhancing measures include:
Soil survey: A survey provides information about soil conditions and possible contamination, giving buyers peace of mind.
Decontamination: Removing contamination can make a plot more appealing to a wider range of buyers, increasing its value by 15-20% when clearing pollutants from construction materials.
Preliminary planning/project development: An approved preliminary plan or concept for potential development clearly demonstrates the potential.
Land maintenance: A well-maintained appearance makes a better first impression and can reduce the effort required to sell.
Even small improvements can have a big impact on the achievable price. An analysis of the value enhancement potential by Auctoa can show you which measures have the greatest leverage for your specific property. This is how you transform unused land into a valuable asset.
Risk Management: Avoid Common Pitfalls in Property Development
The development of an unused plot of land presents not only opportunities but also risks. What pitfalls should you be aware of, and how can you avoid them? A common issue is unexpected costs. Although the prices for building land more than doubled from 2010 to 2020, construction costs can also fluctuate significantly. Therefore, detailed cost planning and contingencies for unforeseen events are essential.
Another risk lies in misjudging the market. High demand in the past is no guarantee for the future. A professional site analysis for your building project helps to realistically assess the current market situation and future trends. Lengthy approval processes can also delay and increase the cost of projects. Early and open communication with the authorities can often work wonders here. Do not underestimate the effort involved in marketing or managing a developed property. A clear strategy and, if necessary, professional support are invaluable to safely realise the potential of your plot.

FAQ
How do I find out the building regulations for my property?
The responsible building authority in your municipality or city can provide information about development plans and the applicable building regulations for your property. A look into the land register can also provide insights into any possible encumbrances and restrictions.
Is it worthwhile to develop an unused plot of land?
Yes, the development (connection to electricity, water, sewage) generally significantly increases the value of a plot of land, as it is then considered ready for construction. The costs for this often range between 7,000 and 10,000 euros.
What role does the standard land value play?
The standard land value is an average value for plots in a specific area, determined by expert committees. It serves as a guideline, but the actual sale price can differ from it (often by up to 20%).
What is property tax C?
Property Tax C is a tax that may be introduced from 2025 for plots that are ready for development but remain undeveloped. Municipalities can levy this tax to counteract speculation and create incentives for development.
