Where you start

How can we help?

01

Investing in property?

An assessment of condition, legal status, buildability and the works required, before you commit capital.

02

Designing or upgrading a building?

Architectural and structural design, permitting, intervention studies and technical support during construction.

03

Developing or building a project?

Structural design of new buildings, geometric documentation, digital surveys and specialist technical support.

Clients abroad

Buying or investing in Greece from abroad?

We act as your eyes on the ground. Inspection, legal and buildability checks, costings and a development scenario, delivered as an English report with photographs, drawings and a clear recommendation.

  1. Before you offer

    A short go / no-go review: titles, permits, unauthorised works, visible structural issues.

  2. Before you sign

    A full DDR with remediation costs, risks and what belongs in the contract terms.

  3. Investment plan

    Permitted floor area, use scenarios, budget and permitting timeline.

  4. Delivery

    Design, permits and supervision with regular reporting while you are away.

International

For architectural practices and engineering consultancies abroad.

Structural analysis and design support, existing-building assessment, retrofit concepts and independent review, delivered within your own file and revision system.

Method

We measure before we decide.

The aim is less uncertainty before every decision: complete information before design starts, fewer gaps in the documentation, and a clear view of technical risk before capital is committed.

That is why we survey with drone, handheld LiDAR and RTK, use field-inspection tools we develop in-house, and in complex or critical structural assessments run supplementary independent calculation checks.

  • Drone photogrammetry
  • SLAM LiDAR
  • RTK GNSS · ΕΓΣΑ87
  • BIM · Scan-to-BIM
  • KAN.EPE · EC8-3
  • Eurocodes
  • OASP seismic screening
  1. First review

    We talk, review documents and photographs, and define exactly what needs answering.

  2. Defined scope

    A written proposal with deliverables, timing and fee. No ambiguity.

  3. Field and analysis

    Inspection, testing, survey, records research and calculations.

  4. Decision

    A report, drawings and a recommendation you can act on straight away.
