Cost of Renovating a 40 sq.m. Apartment

A complete renovation of a 40 sq.m. apartment costs approximately 30,000€. However, the final amount can vary significantly depending on several factors, such as the extent of the changes you want, the quality of materials chosen, and whether special technical solutions or additional work are required.

In this article, you will find a detailed breakdown of the cost of each individual task, from plumbing and electrical work to frames, flooring, and kitchen setup. This way, you will gain a clear picture of what to expect and how to plan your investment accurately.

1. Demolition – Debris removal

During a renovation, doors, frames, tiles, bathroom fixtures, wardrobes, etc., need to be removed. These are collected in debris containers. Renting a container costs around 150€, and for a 40 sq.m. apartment, 2 containers are required, totaling 300€. The cost of demolition and debris removal is estimated at 1,000€.

Total demolition cost (approx.): 1,300€ (1,000€ + 2 × 150€)

2. New walls or Drywall

If drywall needs to be installed or new walls constructed (e.g., for room partitioning), this adds additional cost. For a 40 sq.m. apartment, the average cost is approximately 600€.

3. Plumbing

Renovating plumbing is one of the most critical tasks. It includes new pipes, radiator replacement, and installation of sanitary fixtures. For a 40 sq.m. apartment with one bathroom and one kitchen, plumbing work costs approximately 2,000€. Adding 3 new radiators at 200€ each, including installation (600€), plus a solar water heater costing 1,000€.

Total plumbing cost (approx.): 3,600€ (2,000€ + 600€ + 1,000€)

4. Electrical work

Electrical installations have changed significantly over time. A renovation requires new electrical installations, including multiple sockets, UTP data networks, and alarm wiring. Fiber optic installation and smart home systems could also be added, but these increase the cost significantly. Therefore, we consider a standard installation with a new electrical panel, data network in all rooms, and alarm wiring. The cost for a 40 sq.m. apartment is approximately 3,000€, with an additional 400€ for branded sockets and switches.

Total electrical cost (approx.): 3,400€

7. Wall and Ceiling Skimming

Before painting the walls and ceiling, they must be skimmed with a thin layer of plaster to make them smooth. If only selected areas are skimmed to save costs, walls may appear uneven.

8. Flooring

At this stage, new flooring is installed throughout the house. Tiles are used for the kitchen and living room, wood flooring for the bedroom. Tiles cost 20/m²€, installation with materials 25/m²€. For 20 m² of tiled area: 20 × (20€ + 25€) = 900€. For the bedroom flooring: 250€.
