dobudowanie

Dobudowanie is a construction process in which an additional part is added to an existing building, creating more usable space. It commonly involves attaching a new room, wing, or extension to the original structure, and can occur on ground level or as an upper-level addition. The term is used in Polish architecture and building practice and is related to, but distinct from, other forms of modification such as rozbudowa (broader expansion) and nadbudowa (construction on top of an existing structure).

The process typically includes several stages. First is a feasibility assessment of the existing building’s condition, including structural integrity and foundation capacity, to determine whether the existing structure can safely support the new addition. Next comes project design, addressing architectural integration, loads, connections to the existing building, and compliance with local building codes. Permitting and approvals from authorities are usually required, sometimes with neighbor notification. Construction then proceeds with foundation work if needed, attachment methods that integrate with load-bearing elements, weatherproofing, insulation, and systems integration (electric, plumbing, heating, ventilation, and air conditioning). Finishes and exterior cladding are completed, followed by inspections before use.

Key considerations include compatibility of materials and loads, risk of differential settlement or moisture intrusion, fire safety and accessibility, energy performance, and aesthetic harmony with the original building. Dobudowanie can increase usable space and property value but may raise costs and affect maintenance and energy needs. Related concepts include rozbudowa and nadbudowa.
