Single Storey Extension

A single-storey extension is a fantastic way to add extra space and value to your home. Whether you’re looking to expand your kitchen, create an open-plan living area, or add a bright and airy garden room, a well-designed extension can completely transform your living space. At Kent House Extension Company, we specialise in high-quality extensions across Kent, ensuring that every project meets UK building regulations and is tailored to our clients’ needs.

UK South East Building Regulations for Single-Storey Extensions

Before starting any extension project, it’s crucial to comply with local building regulations. In the South East, key considerations include:

•Structural Integrity – Foundations, walls, and roof structures must be built to support the load safely.

•Insulation & Energy Efficiency – All new extensions must meet current thermal efficiency standards, ensuring your home remains warm in winter and cool in summer.

•Drainage & Plumbing – If your extension affects existing drainage systems, it must be designed to handle rainwater and waste effectively.

•Ventilation & Fire Safety – Adequate airflow and fire-resistant materials are required for a safe and comfortable home.

•Permitted Development vs Planning Permission – Many single-storey extensions fall under permitted development rights, meaning they do not require planning permission, but this depends on size, height, and proximity to boundaries.


At Kent House Extension Company, we handle all regulatory requirements, ensuring a smooth and stress-free process.


Bespoke Finishing Styles for Your Extension

Every homeowner has a unique vision for their extension, and we offer a range of high-quality finishes to match your style and needs:

For a more traditional aesthetic, French doors provide a timeless appeal. With their double-opening design, they offer great ventilation and a charming connection between your home and garden.

3. Sliding Patio Doors – Space-Saving & Contemporary

Sliding doors provide a sleek and space-saving alternative to traditional options. With large glass panels, they maximise views while maintaining excellent insulation.

4. Roof Lanterns & Skylights – Bringing in Natural Light

To create a bright and airy feel, consider adding roof lanterns or skylights. These features flood the space with natural light, making your extension feel even more spacious and welcoming.
