Reconstruction of houses and commercial properties
Reconstruction is required when an existing building must be adapted to a new use, enlarged, strengthened or upgraded technically. It is more complex than a cosmetic renovation because opening a wall or changing a layout can affect loads, stability, moisture behaviour, fire safety and utility routes.
PNV Construction Group works with private houses, apartments, offices and commercial properties. The process starts with a survey of the existing structure, visible defects, available drawings and the condition of building services.
Possible scope
- layout changes and new openings;
- strengthening of foundations, walls, floors, roofs and structural connections;
- extensions, additional storeys, terraces and entrance structures;
- replacement or rerouting of electrical, heating, ventilation, water and drainage systems;
- facade, waterproofing, insulation and moisture-control upgrades;
- coordination of drawings, estimate, programme and staged acceptance.
Why investigation comes first
Existing buildings often contain concealed alterations, corrosion, timber decay, weak masonry or undocumented services. A realistic solution may require local opening-up, measurements, structural input and a review of how rainwater, ground moisture and ventilation affect the building. Demolition should not begin until temporary support and the sequence of structural work have been defined.

Updating services in an existing building
One area of work in existing buildings is updating heating, water supply and other internal services. The starting point is a description of the existing installation and the client’s brief, followed by coordination of equipment locations, pipe routes and the associated removal and finishing work.
The team’s material on renovation and heating upgrades provides a basis for this planning. The scope is defined for the individual building: replacing finishes, altering services and changing structures involve different sets of tasks.
