Reading an Athens Conversion Floor Plan Before You Reserve

Expert source: Peter Maggel, Architect – Head of Construction, Santheos.

Adapted summary prepared by the Santheos editorial team from Peter Maggel’s expert article, “How an Architect Reads a Commercial-to-Residential Floor Plan Before Reservation,” originally published in the Santheos Greece Golden Visa Expert Column on September 8, 2026. This adaptation presents his architectural review approach; it is not a new technical certification or a property-specific legal opinion.

A furnished floor plan makes a proposed apartment easy to imagine. It can show a sofa, a dining table and neatly arranged bedrooms. Peter Maggel’s central point is that a buyer should first understand what the drawing represents. A marketing layout, an existing-condition plan and a documented final configuration serve different purposes. Treating them as interchangeable can hide the questions that matter before a reservation.

For a buyer considering a commercial-to-residential project in Athens, the review should connect the proposed home to the actual building and the relevant property records. The goal is to turn attractive presentation into a set of specific, answerable questions. A drawing can help organize that review, but its appearance alone cannot establish technical suitability, ownership rights or the outcome of an immigration application.

Start with the identity of the drawing

Before studying furniture, ask for the drawing number, issue date, revision, scale and responsible architect or engineer. These details help establish which version everyone is discussing. Then ask whether the drawing records the existing condition, shows a proposed design or describes a final documented layout. A proposal can be useful at an early stage, provided its remaining assumptions and decisions are clearly understood.

This distinction also helps when several documents appear to describe the same unit. If two plans differ, the useful question is which document is current and what explains the change. Buyers should seek an explanation that connects the drawing to the property file rather than choosing the version that looks more appealing. The responsible professional should identify what is established and what still depends on further work.

Compare boundaries and common areas

Place the existing and proposed drawings side by side. Follow the perimeter and locate the entrances. Identify the spaces included in the intended purchase, then distinguish them from corridors, stairs and other common parts of the building. A coloured area on a sales plan does not, by itself, prove exclusive ownership or establish a right to alter a shared space.

An unclear boundary should become a precise question for the project team. Ask how the outline corresponds to the property description and underlying records. Where an intervention involves common parts, technical feasibility and legal rights need their respective professional assessments. The architect or engineer and the appointed lawyer have different responsibilities, and a coordinator can track their answers without replacing either role.

Walk through the proposed home

Maggel suggests reading circulation as if you were actually using the apartment. Imagine entering the building, carrying shopping to the kitchen and moving between the living space, bedroom and bathroom. Check door swings and the space around furniture. Consider how existing windows, structural elements and service routes constrain the proposed arrangement. These practical observations reveal questions that a polished rendering may not answer.

Pay separate attention to main and auxiliary spaces. Ask the engineer how each space is identified in the records and how it is treated in the proposed design. A brochure label such as “bedroom” should lead to a technical explanation, not an automatic assumption. Where daylight, ventilation, clear height, escape, accessibility or drainage is uncertain, request the relevant assessment for that actual building and intended room.

Make each unresolved item actionable

A useful marked-up plan can separate matters that have been explained, matters needing evidence and design decisions still outstanding. Each comment should identify a location and a concrete question. For example, a concern about a bathroom becomes more useful when it asks how the drainage route will work and whether the proposal affects the unit below. This gives the engineer something specific to investigate and answer.

The same method keeps architectural and legal issues distinct. A design question may concern service routing or construction implications. A rights question may concern ownership or an intervention in a common area. Keep the relevant written answers together with the plan so that a reservation decision reflects the evidence actually available, including any features that remain proposals.

Use examples carefully

The source article includes a hypothetical bedroom placed behind a deep internal corridor without an identified external opening. It is an illustration, not a completed Santheos project or a reported client outcome. Its purpose is to show why measured drawings and daylight and ventilation information may be needed before treating a proposed room as workable. No approval or eligibility result can be inferred from that example.

Before deciding

Request an identified and dated plan, compare existing and proposed conditions, clarify boundaries and common parts, and ask how the actual rooms and services have been assessed. Assign unresolved technical questions to the engineer and rights questions to the lawyer. If an essential room, entrance or service route remains unexplained, pause the reservation decision until the relevant written evidence is available.
