Unlike the building of the majority of the residences in the late 1920s, the houses of the Marathon settlement were constructed by Ulen & Company having used modern practices and materials. The settlement was ready within a short time and was equipped with marble stone houses and ancillary areas destined to house the employees and their families. The houses had tar paper roofs, coffered ceilings, and floors made of concrete that were covered with tiles manufactured in Greece. The French-style windows were preferred, as the chief civil engineers suggested, due to their suitability for the Mediterranean countries’ climate. Windows screens were also installed in order to prevent mosquito attacks and appease the fear of malaria. The houses consisted of bedrooms, kitchens which burned wood to function, baths, bathtubs, and toilets. According to oral testimonies, the typical house of a family had four rooms, meaning 2 bedrooms, a kitchen, and a bathroom with a shower. The originally used wood-fired water heater was replaced in the 1950s by an electric one. Ancillary areas such as brick warehouses and ovens were constructed by the tenants themselves.
