Architects currently use cornices and roof soffits in the colour of the façade. When a flat roof on a family house is implemented on a full formwork, it is necessary to provide ventilation of this roof. And since the ventilation of this roof is very important, we recommend choosing a grid in the colour of the façade. If it will be white, then a white grid. If it will be red, a red grille. It is simple details like this that can highlight the quality of your family home.
