The Most Common Mistakes During Renovation – And How to Avoid Them

Mistakes During Renovation

Renovation is a serious commitment that involves not only financial investment but also thoughtful planning and coordination. Many people make critical mistakes in the early stages of renovation, which lead to delays, extra expenses, and disappointing results.

Here are 8 of the most common mistakes made during the renovation process — and expert tips on how to avoid them.

1. Starting the Renovation Without a Predefined Interior Design Project

One of the biggest mistakes is beginning a renovation without a properly developed architectural or interior design plan. A clear project helps you define functional zones, furniture layout, communication points, and the overall aesthetics.

➡️ A well-prepared design increases efficiency and minimizes costly errors during renovation.

2. Failing to Estimate Renovation Costs in Advance

Many people start renovation without a detailed cost estimate. Often, they only consider the price of materials and forget to factor in labor, logistics, and unexpected expenses.

➡️ Use a renovation calculator to plan your budget accurately and avoid financial surprises.

3. Saving Money on Electrical, Heating, and Plumbing Systems

Trying to cut costs on critical infrastructure like electrical wiring, heating, and plumbing can lead to major problems in the future. Mistakes in these areas are often expensive and difficult to fix later.

➡️ Always hire qualified professionals and use high-quality materials for essential systems.

4. Poor Planning of Electrical and Heating Points

If power outlets, switches, or heating systems are installed without considering furniture placement, you may find it difficult to fit appliances or use your space efficiently once the interior is complete.

➡️ Plan furniture layout and utility points early in the design phase.

5. Working With Unqualified Contractors to Save Money

Choosing cheap but unprofessional workers may seem cost-effective at first but often results in poor-quality workmanship and the need for redoing the work.

➡️ Invest in experienced and reputable professionals for long-term value and quality.

6. Overdecorated and Overloaded Interiors

Crowding the space with too many decorative elements or mixing styles can disrupt the harmony of the interior and make it feel cluttered.

➡️ Aim for balance — minimalist and functional interiors are always more comfortable and timeless.

7. Small Living Areas at the Expense of Bedrooms

Some layouts prioritize large bedrooms and reduce the size of the living area. In reality, we spend most of our active time in the living room, and limited space here can feel uncomfortable.➡️ Distribute your space according to your lifestyle, prioritizing common areas where you spend the most time.

8. Lack of Storage Space

One of the most overlooked aspects of renovation is the lack of auxiliary storage — such as closets, laundry rooms, or utility zones. Without proper planning, this leads to clutter and disorganization.➡️ Incorporate practical storage solutions during the design phase.
