Two Storey Extension

A double-storey extension is one of the most effective ways to significantly increase your living space and add value to your home. Whether you’re looking to expand your kitchen and add a new bedroom, create a spacious open-plan living area, or build a dedicated home office, a well-designed two-storey extension can completely transform your home. At Kent House Extension Company, we specialise in high-quality double-storey extensions across Kent, ensuring every project meets UK building regulations and is tailored to your needs.


UK South East Building Regulations for Double-Storey Extensions

When planning a double-storey extension, compliance with UK building regulations is essential. Key considerations include:

     

• Structural Integrity – A two-storey extension requires strong foundations and supporting walls to ensure the load is distributed safely.

• Planning Permission – Unlike single-storey extensions, double-storey extensions often require planning permission, especially if they exceed permitted development rights.

• Thermal Efficiency & Insulation – New extensions must meet high energy efficiency standards to ensure your home remains warm and cost-effective to run.

• Fire Safety & Escape Routes – Fire-resistant materials and adequate escape routes (such as upstairs windows) are required.

• Overlooking & Privacy Considerations – If your extension includes upper-floor windows, it must not directly overlook neighbouring properties to comply with planning regulations.

• Drainage & Services – Additional storeys may require upgrades to drainage, plumbing, and electrics to meet modern safety standards.

We can take care of all the necessary approvals and ensure your extension meets every requirement.

Bespoke Finishing Styles for Your Double-Storey Extension

Your extension should not only be functional but also enhance the look and feel of your home. We offer a variety of finishing styles to suit your preferences:


1. Bifold Doors – Seamless Indoor-Outdoor Living

Bifold doors on the ground floor create a bright, open-plan feel, perfect for connecting your home to the garden. Paired with large first-floor windows, this design floods your space with natural light.


2. French Doors – Classic Elegance

For a more traditional touch, French doors provide a stylish alternative that enhances both classic and modern homes. Double-opening doors create easy access to patios or gardens.


3. Sliding Patio Doors – Contemporary & Space-Saving

Sliding doors offer a sleek, modern look while maximising natural light. They are an excellent choice for extensions that lead onto patios or outdoor entertainment areas.


4. Juliet Balconies – A Touch of Luxury

Adding a Juliet balcony to an upper-floor bedroom or living space provides a stylish feature, allowing fresh air and light without compromising safety.


5. Roof Lanterns & Velux Windows – Maximising Natural Light

For rear extensions, roof lanterns and skylights can transform an upper-floor room by bringing in more light and creating a spacious feel.


6. Brickwork & Cladding Options


To ensure your extension blends seamlessly with your existing property, we offer a range of external finishes:

     • Matching Brickwork – For a natural, cohesive appearance.

     • Render & Cladding – Ideal for a modern, contrasting aesthetic.

     • Timber or Composite Panels – Adds a contemporary touch.
