Holiday parks

We can start with a single home and scale the solution across an entire development – while maintaining quality, design consistency and adapting to local conditions and market requirements.

Modularity gives us the freedom to adapt the space to both the setting and the way you want to use it. We tailor the layout and materials so the house does not simply sit in the landscape, but feels naturally connected to it.

Why ONSO™

  1. Assembled in as little as a day.

    Most of the work happens in our factory, so on-site installation takes days, not months. For selected models, just one day.

  2. Built in-house, start to finish.

    We produce most components ourselves, so we control quality, timing and standard at every stage, backed by 20 years of TLC Group’s experience.

  3. Design without compromise.

    Distinctive, modern architecture shaped around your plot, your brand or your way of living.

  4. Room to breathe.

    Our technology allows generous, open-plan interiors that feel nothing like a typical prefab.

  5. Finished to a premium standard.

    Complete interior and exterior finishes in high-quality materials, with attention to every detail. Little left to do after handover.

  6. Energy-efficient by design.

    EH55 standard and high-performance 8-layer walls, with eco and bio-based materials available.
