About Alexandra

A personal approach, grounded in experience

I’m Alexandra Kostakos, Dipl.-Ing. Architect and founder of Ale Atelier, with a background in architecture, renovation and interiors and more than a decade of professional experience across Greece, Austria and Switzerland.

After years of working within architecture, design and construction, I created Ale Atelier to return to what I value most about this profession: listening carefully, understanding how people want to live, and helping them make thoughtful decisions with confidence.

My approach brings together architectural thinking, interior sensitivity and practical experience — from layout and materials to atmosphere, function and budget. Whether you need clarity on one decision or guidance through a larger project, my aim is to offer personal, thoughtful support shaped around you and your space.

My Approach

One experienced architect. One-to-one guidance. One clear point of contact.

I listen carefully to your needs, priorities, budget and way of living. Whether you prefer close collaboration or clear professional direction, the process is tailored to you—combining architectural, practical and creative guidance to help you make confident decisions for your space.

More than a studio

Ale Atelier brings together architecture, interiors, materials and art through a personal and thoughtful approach.

It is conceived as a place where ideas move beyond the screen—where spaces are explored with care, materials can be experienced and every project is shaped around the person behind it.

Art by Ale Atelier will be introduced soon.
