Renovating an existing building is often a more complex task than building a new one.
Existing structures, previous alterations, hidden defects and the building’s own particularities can raise technical questions that can’t simply be answered by applying a familiar, standard solution.
B2 Házak undertakes complete building renovation, restoration, extension and conversion work, whether the building is residential, commercial, industrial or any other use. Our references include the conversion of a residential building, an industrial building and a hospital.
In our renovation work, we place particular importance on preparation, on properly understanding the existing condition, and on making sure every problem gets a technically justified solution that fits the specific building.
In a complete building renovation, several of the existing building’s structures and systems are renewed at the same time.
The work can affect, among other things:
In a project like this, it is especially important that the individual interventions are treated not as separate tasks, but as one interconnected system.
With existing buildings, what is sometimes needed is not a simple upgrade but a structural or architectural restoration.
This can include, for example:
Before any restoration, the first step is always to understand what caused the problem — only then does it make sense to decide on the right way to fix it.
When extending an existing building, the new structure has to be properly joined to the existing one.
The extension can involve:
The connection between the existing and the new structures always needs special attention, because different structural systems, foundations, materials and construction periods can meet one another.
Converting a building’s interior can be much more than a simple cosmetic refresh.
The work can change:
For a larger conversion, the demolition, structural and trade work already have to be coordinated during design and preparation.
New construction typically starts from known, designed structures.
With an existing building, however, it often only becomes clear what the actual condition really is after a site survey, a review of the documentation, or opening up certain structures.
That is why, when preparing a renovation, the following can matter:
Proper preparation is not unnecessary extra work — in many cases, it is exactly what prevents costly repairs and redesign later on.
With existing buildings, two seemingly similar problems can have completely different causes.
That is why properly fixing a crack, dampness, an insulation defect or a structural problem is not simply a matter of automatically repeating a solution used before.
The work has to start with understanding the cause of the problem.
Fontosnak tartjuk, hogy ne az legyen a döntés alapja, hogy „így szoktuk” vagy „eddig ezzel nem volt probléma” — hanem az, hogy:
That is why, during renovation, an analytical technical approach and proper problem-solving matter just as much as experience.
During renovation, conditions often come to light that weren’t visible at the design stage.
Behind a stripped-out finish, a different layer build-up can appear than expected. A previous alteration can differ from the original plans. An old structure’s condition can often only be properly judged once it has been opened up.
In cases like this, construction can’t simply stop just because reality differs from the plans.
What matters is that the discrepancy is interpreted correctly from a technical standpoint, and that — together with the necessary consultation with designers or experts — the right solution is found.
This is where construction experience and coordination between the different trades matter especially.
One of the critical areas of any renovation is the connection between new and existing structures.
This can include, for example:
For these, it’s not just the structural connection that has to be solved — moisture protection, thermal performance, movement, expansion joints and later use all need to be taken into account too.
For a larger renovation, demolition alone requires serious preparation.
The demolition sequence has to be planned so that, throughout the process:
A bontás tehát nem pusztán „eltávolítás”, hanem a következő kivitelezési szakasz előkészítése is.
A larger building renovation is also a good opportunity to reduce the building’s energy consumption.
This can include:
With energy upgrades, however, it is especially important that the individual interventions are treated as one working system.
Not every existing building needs the same solution.
For a renovation project, it can help even at the first discussion to send over any available plans, previous documentation, photos, and a short description of the planned conversion.
The first step is determining what technical work is actually needed to achieve the result you want.
