What a house reconstruction includes
A house reconstruction starts with a real assessment of the condition of the property, not with promises based on photos. It is a complex project in which demolition, remodelling, new construction, roofing work, the facade and the finishing stages have to be thought through as one system.
The scope may include extensions, the roof, the facade, interior spaces, plumbing, electrics and finishing stages. The real value lies in coordinating all of this work so that the different jobs do not block each other, do not create costly mistakes later and follow a clear order of execution.
For the owner, this means a clearer framework for decisions, better control over the project and less risk in a service that, by its nature, leaves no room for improvisation. In house renovation and house reconstruction, the result depends not only on who does the work, but on who manages the whole process, the timelines and the critical technical stages.

Types of projects we work on
Reconstruction of an old house
Suitable for properties with outdated plumbing and wiring, worn-out elements and a need for substantial work to reach a new standard of living.
House extension
When the existing floor area is not enough and new spaces need to be added with a clear connection to the current house.
Full refurbishment
A complete plan for the facade, roof, plumbing and electrics, interior and the finished look of the property as one overall solution.
Partial reconstruction
When the project is phased but still requires strong planning, technical coordination and control over the work.
Process
How we work
We work in an orderly sequence – predictably, with control over every stage and without chaos while the work is under way.
Site visit
We assess the current condition of the house, the critical areas, the possible risks and the real scope of the project.
Analysis and planning
We map out the changes, the technical dependencies and the logic of the stages, so the project is manageable from the very start.
Quote
We prepare a clear framework for the stages, the budget and the sequence of execution, instead of a lump-sum price with no structure or accountability.
Execution
We coordinate demolition, construction, the roof, the facade, plumbing and electrics, and the interior stages according to a consistent plan.
Quality control
We monitor quality at key points, so the complex project is completed soundly and without haphazard compromises.
Our expertise
A house reconstruction needs management, not just execution.
With houses, mistakes in the order of the stages turn into delays, rework and costly compromises. That is why this work needs organisation, technical discipline and clear responsibility for the whole project - from assessing the condition of the house to the final handover.
- planning the stages
- coordinating the work
- control over execution
We take on this responsibility from the first site visit to the final result, so the complex project stays manageable and predictable for the owner.
We work with clients who want a long-term solution, not the lowest price.
This service is for owners who understand that, in a reconstruction, a cheap compromise almost always ends up costing more later.
What we value
- clear process
- control over the project
- long-term result
If you are looking for the lowest price, we are probably not the right choice for this type of project.
A written warranty
Every completed project receives a warranty certificate. This is what it covers and for how long.
- 2 years on all work
- Construction, renovation and finishing work on the property.
- 6 years on plumbing, electrical and roofing work

- Written certificate

The extended term applies to the installations themselves and to the roofing work. Installed ready-made products — taps, fittings, appliances — carry the manufacturer's warranty.
