How House Extensions Work

Our house extensions utilize the same high-quality construction methods as our standalone cabins - either SIP panels or log construction. The key difference is the integration process: we carefully remove one wall of the extension unit and seamlessly connect it to your existing home. This creates a natural flow between spaces while maintaining structural integrity. With extensions up to 40 square meters, you stay within legal limits that don't classify the addition as a separate dwelling, simplifying permissions and reducing costs.

Essential Guidelines for an Extension Project

To ensure your extension meets both quality and regulatory standards, please review the following key considerations.

  • Extension size: Our standard extensions can be up to 40 m² to comply with local building regulations.
  • Construction time: The standard price applies to projects that take up to 10 days to complete. Larger or more complex builds may require additional time and cost.
  • Clearance requirement: A minimum 0.7 m clearance must be maintained around the extension for proper installation and maintenance access.
  • Individual evaluation: Every extension project is unique. The final valuation depends on the build time, size, and construction complexity.

These guidelines ensure smooth project delivery, cost transparency, and long-term structural performance.

Benefits of House Extensions

Legal Compliance & No Planning Permission

Extensions up to 40m² typically don't require planning permission and won't be classified as a separate dwelling, making the process faster and more cost-effective.

Seamless Integration with Existing Structure

By removing one wall and connecting to your existing house, we create a natural flow that feels like part of the original building rather than an addition.

Choice of Construction Methods

Whether you prefer the energy efficiency of SIP panels or the natural warmth of log construction, we can match your extension to your preferences and existing home style.

Rapid Installation & Minimal Disruption

Prefabricated panels and logs mean faster construction times, reducing the disruption to your daily life while extending your living space.

Enhanced Property Value

A well-designed extension can significantly increase your property value while providing additional living space for your growing family needs.

Energy Efficient Addition

Both SIP and log extensions offer excellent insulation properties, ensuring your new space is comfortable year-round while keeping energy costs low.
