Understanding Double Story Side Extensions

Need more space? Thinking about boosting your home’s value? Double story side extensions could be your answer. They offer a smart way to expand without eating up your garden.

Why consider a double story side extension? For starters, it gives you extra space to play with. Imagine having a couple more bedrooms, a home office, or even a larger living area. It’s perfect for growing families who need that bit of extra room.

Benefits of a double story side extension:

• Additional space: More rooms for sleeping, working, or relaxing.
• Enhanced property value: A bigger home can often mean a higher selling price.
• Improved functionality: Redesigned layouts can make your home work better for you.

Common uses:

• Extra bedrooms: Ideal for expanding families.

Costs Involved in Double Story Side Extensions

Thinking about a double story side extension? It’s crucial to understand the costs. Various factors can impact the overall expense, so let’s break it down.

Factors affecting costs:

• Materials: Quality and type of materials can significantly affect costs.
• Labor: Skilled labor and contractor fees vary based on location and complexity.
• Design complexity: More intricate designs require more time and expertise.
• Location: Costs can fluctuate based on the region and local regulations.

On average, a double story side extension can range from £1,500 to £2,500 per square meter. This estimate includes both materials and labor. But that’s just the start.

Additional expenses:

• Planning permissions: Necessary for most extensions, these can add to your costs.
• Building regulations: Ensuring compliance with local laws can incur extra fees.
• Contingency fund: Always set aside around 10-15% of your budget for unexpected expenses. Things can crop up during construction that you didn’t foresee.

Budgeting tips:

• Get multiple quotes: Don’t settle for the first estimate. Compare options to find the best fit.
• Prioritize needs: Decide what’s essential and what can be scaled back if needed.
• Plan for the unexpected: Having a contingency fund helps keep your project on track without financial stress.

Understanding these costs helps in planning your double story side extension effectively. Breaking down each element ensures you’re well-prepared for the financial aspects of your project. For inspiration, check out our recent project on transforming a dated Victorian terraced house into a modern open-plan living space through a side extension in Waltham Forest.

Planning Permission and Regulations

Planning a double story side extension? You need to navigate planning permission and building regulations. Let’s make it easy.

Planning permission and permitted development rights aren’t the same. Planning permission: Required for most extensions, especially larger ones. This involves submitting plans to your local planning authority (LPA) for approval.

Permitted development rights: Allow smaller extensions without full planning permission. For example, terraced or semi-detached homes can extend up to 6 meters, and detached homes up to 8 meters, within certain height and material restrictions.

Key regulations to consider:

• Height: Your extension can’t be taller than your existing house.
• Distance from boundaries: Rear extensions must have at least 7 meters from the rear boundary.
• Roof pitch: Should match your existing property.
• Windows: Side-facing windows must be obscure-glazed and non-opening.

Practical advice for navigating the approval process:

• Consult with local planning authorities: Early conversations help clarify requirements and streamline your process.
• Prepare necessary documentation: Include detailed plans, elevations, and any other required information. Your architect can assist with this.
• Respect neighbors’ privacy and character of the area: This is crucial for getting approval. For instance, our recent project in Wandsworth involved a contemporary side extension that was designed to enhance natural light and modernize key living spaces while respecting the Victorian character of the neighborhood.

Understanding these regulations helps ensure your project complies with local laws, avoiding costly delays. It’s all about being prepared and informed.

Design Considerations for Double Story Extensions

Designing a double story side extension isn’t just about adding space. It’s about making sure that new and existing elements blend seamlessly. You want your extension to feel like a natural part of your home.

Start with the roof pitch. Matching the pitch of your existing roof creates a harmonious look. It avoids that “bolted-on” feeling.

Window placement is another key factor. Align new windows with existing ones to maintain aesthetic balance. Think about privacy too. Use obscure glazing for side-facing windows to keep things discreet.

Material choices matter. Use similar materials to your existing home. Whether it’s brick, render, or wood, consistency is key. This keeps the overall look cohesive.

Optimising natural light is crucial. Consider full-length skylights or large windows. They can flood your new space with light, making it feel open and airy.

Functional spaces are a must. Design areas that cater to your family’s needs. Think about:

• Flexible family spaces: Rooms that can adapt as your family grows.
• Storage solutions: Built-in storage to keep things tidy.
• Multi-purpose rooms: Spaces that can serve different functions over time.

Working with experienced architects, like us at TA+ Studio, ensures your design is both practical and beautiful. We focus on creating spaces that evolve with your family, making your home work better for you.

For example, our Tonbridge project transformed a two-bedroom house into a family-friendly home with an open-plan design that integrates seamlessly with the garden. This project included a rear extension and a new loft conversion, providing additional rooms and a private master suite.

When planning your double story side extension, think about how each design choice can enhance your home’s look and function. It’s all about creating a space that’s both seamless and functional.

Tips for finding reputable professionals:
