Yes, but not every change can be made directly on the construction site.
After the building permit is issued, the building must be constructed in accordance with the approved investment design documentation.
What changes are most common?
For example:
- moving doors or windows;
- changes to internal walls;
- combining rooms;
- changes to the facades;
- structural changes;
- relocating plumbing or electrical installations.
Whether the change is permissible depends on what exactly it affects.
Substantial and non-substantial deviations
The Bulgarian Spatial Development Act (ZUT) distinguishes between substantial and non-substantial deviations from the approved project.
More significant changes may affect:
- the structural design;
- the use of the rooms;
- the installations;
- the facades;
- the regulatory requirements;
- the provisions of the Detailed Development Plan (PUP).
In some cases, it is necessary to amend the approved investment design documentation and supplement the building permit.
Why should we consult the architect first?
A change that seems small can affect several design disciplines.
For example, a new opening may require a review by a structural engineer, and the relocation of a bathroom may require changes to the water supply and drainage design.
Therefore, the change must first be discussed with the architect and the relevant engineering consultants.
When is the best time to make changes?
It is best to clarify the main decisions before starting construction.
Changes during construction can result in additional design work, costs and delays.
Do you need to amend an approved design?
Garant-21 architectural studio can review the specific case and determine what design changes and procedures are necessary.
