Idealny dom 100 m2 z keramzytobetonu Jak się w nim mieszka? - Pomysł na Dom #129

Summary

The video tours Dawid’s modern, barn-style home, built from prefabricated expanded-clay concrete. At 98.5 m², it is smaller than many Polish houses, but its open living area, high ceilings, and large windows make it feel more spacious. The family says the compact layout suits their needs.

Design and everyday-use choices

• Dawid adapted the original design to add a separate toilet, enlarge the entrance hall for a deep coat cupboard, and reduce the size of the utility room.
• The compact kitchen includes the essentials: a large refrigerator, an induction hob with an integrated extractor, a built-in oven and microwave, an air fryer, and plenty of storage. Deep cabinets also serve as a pantry.
• The family chose a shower instead of a bathtub because they did not use one. Dawid notes that a tub would have fit.
• The house includes a main bathroom, a separate toilet, a utility room, attic storage, the parents’ bedroom, and three children’s bedrooms.
• The parents chose a modest bedroom and wardrobe area because their previous, larger bedroom had mostly gone unused. A mirrored wardrobe wall helps the room feel bigger.
• Dawid’s general planning lesson is to avoid adding floor area you will not use. He estimated that an extra 12 m² could cost roughly PLN 60,000, at about PLN 5,000 per square metre.

Construction and materials

• Dawid chose prefabricated expanded-clay concrete mainly for the speed of construction. The structural walls are made from C20/25 concrete, and the house has a full-slab foundation.
• He says the expanded clay improves insulation and acoustic performance while reducing the material’s weight for transport. The structural walls can also be thinner, leaving more usable space inside.
• The walls arrived with smooth surfaces that needed only minor repairs before painting. Dawid chose a rougher wall finish in one area for a decorative plaster treatment he applied himself.
• Construction progressed quickly:
  • The foundation slab was poured on June 6.
  • The walls were erected on June 16.
  • The roof structure followed on June 18.
  • After a wait for the large windows, work resumed in mid-August.
  • The interior was finished by the end of September, and the family moved in by December—less than six months after construction began.
• Dawid reported a total cost of about PLN 520,000, including the slab and selected extras. This was based on a contract signed in December 2023 and included facade blinds, large HST glazing, and other design features.

Notable features

• A tall, bright living room with glazing reaching about 4.75 m and a ceiling height of roughly 5.25 m at its highest point.
• A threshold-free HST sliding door that is easy to operate and can accommodate wheelchair access.
• High windows in the children’s rooms, along with an additional fixed window and facade details added to the original design.
