Loan for renovating an old house

March 27, 2025·4 min read· News

Deciding to renovate an old house is not only a matter of its age but, above all, its technical condition and the time that has passed since the last renovation. The longer a building remains without a thorough renovation, the higher the potential costs of modernization—and the more likely you are to need a loan for renovating an old house. In addition, the renovation of an older building may require adapting it to current technical and energy efficiency standards. It's also worth noting that if the building is listed as a historic monument, renovation work requires the approval of a conservation officer. This can mean restrictions on the types of materials used, the methods of work, or even the color scheme of the façade. Moreover, if the house features a regional architectural style, it's worth ensuring that the renovated property still fits in with its surroundings. All of this can affect the final renovation costs—but don’t worry, a loan for renovating an old house (or any house, because not only old houses need renovations—and our renovation loan isn't just for old buildings) can help. Let’s break down the renovation of an old house into several key categories. Depending on what exactly you want to do, your approach—and the cost—can vary.

Loan for home modernization

Modernizing an old house can involve many aspects — from improving energy efficiency to implementing modern technology. The most common modernization works include:

• Thermal modernization: insulating walls, replacing windows and doors with energy-efficient ones, installing a modern heating system • Installation of renewable energy sources: solar panels, heat pumps, or solar collectors • Smart home systems: automation of heating, lighting, or building security systems

The final cost of modernizing an old house depends on the scope of the work (and, of course, that determines how large a renovation loan you’ll need). For example:

• Insulating a 150 m² house: approx. 40,000 to 70,000 PLN • Replacing windows and doors: around 20,000–50,000 PLN • Installing a heat pump: 30,000–70,000 PLN • Installing solar panels: 25,000–45,000 PLN

Loan for home reconstruction

Reconstruction involves structural changes to the house, such as demolishing or moving walls, changing the layout of rooms, or converting the attic. In Poland, reconstruction must comply with building law, and in some cases, a building permit is required. Be sure to consider this aspect.

So how much of a renovation loan might you need in this case? Typical costs of reconstruction include:

• Demolishing a load-bearing wall: 5,000–10,000 PLN • Changing room layout: 20,000–50,000 PLN • Converting the attic into a living space: 40,000–100,000 PLN

Loan for home expansion

Home expansion means increasing its usable area — for example, by adding new rooms or another floor. This requires meeting technical and legal standards, including obtaining a building permit. It’s also important to match the new section to the style of the entire house — unless the expansion is so major that it changes the entire style.

In this case, you might need a higher renovation loan, since the cost of expansion, depending on the scope of work, may be:

• Adding a 20 m² room: 50,000–80,000 PLN • Building an additional floor: 150,000–300,000 PLN • Strengthening foundations (if required): 20,000–50,000 PLN

Loan for roof renovation

The roof is one of the most important elements of a house, and its renovation or replacement is essential for comfort and safety. In Poland, various types of roofs are used — gable, hip, mansard, or flat. Each type requires an individual renovation approach.

Also, if you plan to install solar panels along with (or after) the roof renovation, you need to consider extra aspects. The roof must have the right tilt and durability, which could involve extra reinforcement work.

In this case, you might need a smaller renovation loan, as estimated costs for roof work are:

• Replacing the roof covering (e.g., metal roofing, ceramic tiles): 100–200 PLN/m² • Complete roof renovation of 150 m²: 30,000–75,000 PLN • Reinforcing the structure for solar panels: 10,000–20,000 PLN
