How can we help?
Each service supports a specific decision. Choose your starting point and we will help define what comes next.
“I am buying a property or land”
We identify early warning signs before an offer or CPCV and explain what needs to be verified.
View Safe Purchase →“I need to know what is possible”
We test the scenario, identify constraints and define a technical and planning strategy.
View Planning Feasibility →“I want to design and obtain approvals”
We turn the confirmed scenario into a coordinated design and support the process through to construction.
View Design and Licensing →“I have an existing building to regularise”
We assess the existing situation, define the viable route and support the regularisation process.
View Building Legalisation →The route is not the same for every project: Safe Purchase detects preliminary risks; Planning Feasibility tests the scenario and defines the strategy; where needed, a PIP obtains the municipality’s position; Design and Licensing implements the confirmed direction. Building Legalisation is a separate route for issues affecting existing construction.
