What is an XXL Building Blocks House?
An XXL building blocks house refers to a play construction made of oversized plastic or foam blocks that is large enough for children to crawl into, sit in, or walk through. Unlike classic toys like Duplo or Mega Bloks, these building blocks reach dimensions of about 30 × 15 × 9.5 cm for 8-point blocks, while Riwi building blocks are significantly larger at 71 × 20 × 10 cm, allowing for even more impressive structures. This makes them large enough to build real walls and roofs. XXL building blocks are particularly large-format, robust building blocks that are ideal for creative building projects and impressive constructions.
An important difference with XXL building blocks is the size of the individual blocks. While many brands offer smaller building blocks, Riwi building blocks are significantly larger. This means that fewer blocks are needed for a comparable structure. Thus, smaller sets from Riwi are often sufficient to build stable and walk-in houses. This not only saves space during storage but also facilitates assembly and handling for children. Due to the larger dimensions of the Riwi building blocks, creativity is also stimulated, as impressive structures can be created quickly with fewer elements.
The special thing about these systems: The blocks are modular and can be recombined over and over again. A house today, a knight's castle tomorrow, a tunnel for ride-on cars the day after. The connection works via a plug-in system with studs, completely without glue or additional connectors. This creates stable structures that children can assemble and disassemble independently.
Benefits of an XXL Building Blocks House for Children
Why are more and more families and institutions choosing large building block houses? The key lies in the unique interplay of movement, creativity, and social learning in life-size.
The numerous play possibilities with XXL building blocks stimulate children's imagination, promote their motor skills, and enrich shared play in a variety of ways.
Motor Skills & Coordination
Stacking, plugging, and dismantling the large elements trains fine motor skills right from the first year of life. Children learn to dose their strength and develop better hand-eye coordination. At the same time, gross motor skills are addressed by carrying and positioning the blocks.
Creativity & Imagination
With XXL building blocks, there are no limits to the imagination. The diverse play possibilities encourage children to create ever-new structures, promote their creativity, and let them develop motor skills through play. Children invent their own house shapes, experiment with colors and constructions, and experience how abstract ideas become tangible buildings. The possibilities range from a simple garage to a multi-story fantasy castle.
Social Learning
Building together promotes teamwork, agreement, and conflict resolution. When several children work on a house, they must communicate, distribute roles, and find compromises. This makes XXL building blocks ideal for:
- Daycares and playgroups
- Children's birthdays
- Families with several children
- Therapeutic facilities
Self-Efficacy
The experience of creating a walk-in house from individual blocks enormously strengthens self-confidence. Children see the result of their work immediately and develop problem-solving skills, for example, if a wall is not stable enough and needs to be reconstructed.
Promotion of Movement
In contrast to small-scale toys, an XXL building blocks house gets children moving. Crawling, going in and out, bending, and stretching. The whole body is therefore active during play.
Theme Worlds for Role-Playing
Thematic projects are particularly popular:
- Fire station with red coloring
- Play shop with sales window
- Knight's castle with battlements
- Garage for Bobby-Cars and ride-on vehicles
