Grammatiki joined Eckersley O’Callaghan in 2021. She is responsible for a range of facade engineering activities including the construction details of different typologies of facades, glazed facades, cladding systems, thermal calculations, and glass sizing calculations.
In 2020 her thesis work at TU Delft which explored a novel structural connection system for glass bricks, received an honourable mention. Grammatiki alongside her colleagues was awarded second price in the 2017 Greek National Competition, “Colour in Architecture”. The entry explored various facade engineering principles by developing a system of movable louvers on an abandoned building. The project followed strong sustainable design principals.
