Major renovation is a complete transformation of a living space, like turning a caterpillar into a butterfly. Unlike simple cosmetic updates, it affects all systems of the building — from the foundation to the roof. Planning requires attention to many details: from the condition of load-bearing structures to load calculations on engineering systems.
Modern turnkey renovation combines dozens of specializations. Electricians, plumbers, finishers work as a single mechanism. With the structural features of the building in mind, a comprehensive approach to project implementation is formed.
Major renovation of a private home begins long before the first hammer strike. Developing a design project defines the future look of the house and the technical solutions for all systems.
According to construction experts, properly executed major renovation extends a home’s lifespan by 25–30 years and increases its market value by 40–60%.
Step-by-step planning of a major renovation
The stages of major renovation follow strict logic. Breaking the sequence leads to rework and extra costs. In one project, the floors had to be completely redone due to premature installation of plumbing.
Demolition work opens new possibilities. Removing partitions, old finishes, and outdated utilities is the first step toward renewal.
Rough work includes replacing utilities and creating a new engineering foundation for the home. Electrical wiring is replaced according to modern safety standards with circuit breakers and RCDs. Plumbing and sewage are upgraded with durable materials — polypropylene for hot water, PVC for sewage.
Wall and ceiling leveling completes the preparation stage. A quality floor screed provides the base for any finish.
Construction and repair work in the middle stage includes insulation and waterproofing. Insulating the facade with modern materials reduces heat loss by 30–40%. Installing new windows and doors improves energy efficiency.
Finishing is the final chord of the renovation symphony. Finish work requires precision and attention to detail. Every stroke matters for creating a harmonious interior.
Cost and duration of a major renovation
How much does it cost to turn an ordinary house into a modern home? The cost depends on many factors. Area, architectural complexity, and materials all influence the final amount.
The average cost of a major renovation ranges from $80 to $200 per square meter. Premium finishes can reach $350–500 per m², including exclusive materials and designer solutions.
Timelines balance quality and speed. A 150–200 m² house is renovated in 4–6 months with a well-coordinated team. Winter conditions are known to increase the duration of exterior work by a third.
In practice, rushing is the enemy of quality. The best time to start is late spring when weather conditions favor all types of work.
Clear supply planning prevents downtime. Every day of delay increases the total cost of the project.
