Transforming Your Kingston Upon Thames Home: A Guide to Double Storey Extensions in Surbiton Tolworth

Kingston upon Thames, with its charming suburbs like Surbiton Tolworth, offers a quintessential English lifestyle. But as families grow or needs change, even the most beloved home can start to feel a little cramped. That’s where a double storey extension comes in – a brilliant way to add significant living space and unlock the full potential of your property.

This comprehensive guide delves into the world of double storey extensions in Kingston Surbiton Tolworth, equipping you with the knowledge to make informed decisions for your dream home.

Unleashing Potential: Reasons to Consider a Double Storey Extension

  • Creating a Room for Every Dream: Imagine a light-filled master suite with a luxurious en-suite bathroom, a dedicated home cinema for family movie nights, or a spacious playroom for the kids. A double storey extension allows you to design rooms that perfectly suit your lifestyle.
  • Maximizing Space: Double storey extensions don’t just add square footage; they add usable space. By extending upwards, you avoid sacrificing valuable garden area, a common concern with single storey extensions.
  • Enhancing Property Value: A well-designed double storey extension can significantly increase the value of your Kingston upon Thames home. The extra living space and modern features are highly sought-after by potential buyers.
  • Improved Functionality and Flow: Often, existing layouts can feel disconnected. A double storey extension creates a more cohesive flow throughout your home, making it easier to navigate and enjoy.
  • Natural Light Extravaganza: Double storey extensions allow for the incorporation of large windows and skylights, bathing your new space in natural light and creating a sense of spaciousness.

Considering the Options: Types of Double Storey Extensions

  • Wraparound Extension: This versatile extension embraces both the side and rear of your home. Perfect for creating a large open-plan kitchen, dining, and living area, seamlessly connecting your indoor and outdoor spaces.
  • L-Shaped Extension: Ideal for maximizing corner plots, L-shaped extensions provide ample space for a variety of purposes, such as a kitchen extension with a utility room or a master bedroom with a walk-in wardrobe.
  • Over Basement Extension: If you have an existing basement, a double storey extension built on top can create a stunning and practical addition. This option is particularly well-suited for creating a home office or a separate living area for teenagers.

Navigating the Process: Planning and Permissions

  • Consulting an Architect: An experienced architect will guide you through the entire process, from initial ideas to planning permission and construction. They’ll ensure your extension complements your existing home’s style and maximizes its potential.
  • Planning Permission in Kingston Upon Thames: Understanding planning regulations is crucial. Kingston Council offers clear guidelines on their website https://www.kingston.gov.uk/. In many cases, double storey extensions fall under permitted development rights, but it’s always best to consult with a professional to ensure compliance.
  • Building Regulations: Building regulations ensure the structural integrity and safety of your extension. An architect or structural engineer will ensure your design adheres to these regulations.

Building Your Dream: The Construction Phase

  • Choosing a Reputable Builder: Kingston Upon Thames boasts a wealth of experienced builders specializing in double storey extensions. Look for builders with a strong reputation for quality craftsmanship, clear communication, and adherence to deadlines.
  • The Build Process: The construction phase can be disruptive, but a good builder will minimize inconvenience. Expect scaffolding, foundation work, bricklaying, electrical rewiring, and plumbing installations.
  • Project Management: An architect or project manager can oversee the construction process, ensuring everything runs smoothly and according to the agreed-upon plans and budget.

Living Large: Finishing Touches and Design Inspiration

  • Interior Design: This is your chance to create a space that reflects your personality. Consider open-plan layouts for a modern feel, or incorporate traditional elements to seamlessly blend the extension with your existing home.
  • Natural Light: Large windows, skylights, and strategically placed mirrors will maximize the natural light in your new space, creating a bright and airy feel.

Beyond the Bricks and Mortar: Additional Considerations for Your Kingston Upon Thames Double Storey Extension

While the construction process is paramount, a successful double storey extension goes beyond the physical build. Here are some additional factors to consider:

  • Budgeting for Success: Double storey extensions can be a significant investment. Carefully consider all costs involved, including architectural fees, building materials, labor, building regulations approval, and potential unexpected expenses. Obtaining quotes from multiple builders is crucial to ensure you get the best value for your money.
  • Letting There Be Light (Naturally): Kingston Upon Thames enjoys ample sunshine hours. Take advantage of this by incorporating large windows and skylights into your design. Well-placed windows not only bathe your extension in natural light but also create a connection to your outdoor space, making the new area feel even more expansive.
  • Garden Integration: Double storey extensions shouldn’t come at the cost of a beautiful garden. Clever design can ensure your extension complements your outdoor space. Consider bifold doors that open up entirely, creating a seamless flow between indoors and outdoors. Roof terraces on top extensions can also provide a fantastic outdoor living area.
  • Building Regulations and Party Walls: If your extension is built close to a boundary wall, you may need to follow party wall regulations, which govern communication and potential cost-sharing with your neighbor. An experienced architect can guide you through this process.
  • Embrace the Period Charm: Surbiton and Tolworth boast a rich architectural heritage, with Victorian and Edwardian terraces being a common sight. When planning your extension, consider incorporating elements that complement the existing style of your home. This creates a cohesive and aesthetically pleasing overall look.
