Although the word “eco” implies maximum proximity to the natural environment, very often such housing is built in the heart of the metropolis. The eco-house, located in a busy part of town, has special requirements, one of which is to protect personal space without compromising the interior. The facade of the house does not necessarily have to be fenced off from the outside world, it can go directly to the busy street, then instead of large window frames will be enough to set a thin narrow windows that will provide fresh air circulation. Eco style is the maximum possible use of natural energy sources. To compensate for the lack of natural light, skylights should be installed in the ceiling of the foyer – they provide good lighting and at the same time allow you to hide the interior of the house from prying eyes.
