Albahri-Innenausbau · Updated:
Assess each building individually
The age and appearance of a building are not enough to establish wall construction or service condition. Alterations from different periods may meet in the same room. Drawings and professional investigation help establish what is actually there.
Also check which elements belong to the apartment and which are common property. Required approvals must be clarified before work begins.
Check listed status early
If a building is listed, discuss proposed changes with the relevant district heritage authority beforehand. Individual elements or interiors may also be protected.
Berlin's heritage authorities provide information about the approval process. An interior fit-out plan does not replace that consultation.
Check other approvals
Whether a project requires permission depends on the specific intervention and location. Refer structural, change-of-use or conservation-area questions to the appropriate specialists and authorities.
Do not begin removal while required approvals or investigations are outstanding. This helps avoid preventable interruptions.
Base contingencies on the existing conditions
Uneven floors, concealed services and older materials may require additional work. Record the assumptions behind a quotation and how new findings will be handled.
Clear work stages and documented agreement on changes are useful. Broad promises about cost and duration offer little certainty when existing conditions are unknown.
