The 114 m² 3+1: a family house with a pantry and two balcony doors

"3+1" is Turkish shorthand for three bedrooms plus a living room. This two-storey prefab house puts the shared rooms downstairs and all three bedrooms upstairs. The ground floor has a 1.5 m² entrance, a 6 m² hall, a 24 m² living room, a 10 m² kitchen, a separate 2 m² pantry and a 2 m² WC. On the upper floor, a 5 m² hall leads to bedrooms of 15 m², 10 m² and 10 m² and a 6 m² bathroom.

What the room sizes mean for everyday life

The 24 m² living room is large enough to divide into a sofa area and a dining area without either feeling squeezed. Next to the 10 m² kitchen, the pantry is a real advantage for families who buy in bulk, preserve food or keep larger appliances out of sight – it keeps the kitchen worktops clear.

Upstairs, the 15 m² room naturally becomes the parents' bedroom, while the two 10 m² rooms work well as children's rooms of equal size, or as one child's room and one study or guest room. The specifications list two bathrooms: the bathroom upstairs serves the bedrooms, and the WC downstairs saves trips upstairs during the day and when guests visit.

Two PVC balcony doors give access to outdoor areas and bring extra daylight into the house – think about which side of your plot you want them to face.
