HOUSE EXTENSIONS

Why Work With Us?

Adding an extension to your house is one of the most effective ways to expand your living space and enhance the overall functionality and value of your home. Whether you're looking to create a larger kitchen, add an extra bedroom, or design a new living area, a well-planned extension can transform your home to better suit your needs and lifestyle.

A house extension allows you to increase your property’s square footage without the need to relocate, offering a flexible and tailored solution to meet your growing family’s requirements or to create that dream space you’ve always wanted. With expert architectural guidance, your extension can seamlessly blend with the existing structure, enhancing both the interior and exterior aesthetics of your home.

Benefits of Adding an Extension to Your House

More Living Space

One of the most obvious benefits of a house extension is the additional space it provides. Whether you need more room for a growing family, a home office, or simply a more spacious living area, an extension can give you the extra square footage you need.

Avoid the Stress of Moving

Rather than dealing with the hassle and cost of moving to a larger home, an extension allows you to stay in your current location while enjoying all the benefits of a bigger space.

Increase Property Value

A well-designed extension can significantly boost the value of your home. Whether you’re planning to sell in the future or simply want to invest in your property, an extension is a smart way to enhance your home’s market appeal.

Tailored Design

An extension gives you the opportunity to design a space that meets your specific needs and complements your lifestyle. From open-plan kitchens to luxurious master suites, the possibilities are endless.

Enhance Natural Light

Thoughtfully designed extensions can introduce more natural light into your home through the use of large windows, skylights, or glass doors, creating a brighter and more welcoming environment.

Our architectural services ensure that your house extension is not only functional but also aesthetically pleasing and in harmony with the existing structure. We take the time to understand your vision, create detailed plans, and manage the entire process from concept to completion, ensuring a smooth and stress-free experience.

Feasibility Visits for House Extensions

Just like loft conversions, not all houses are ideal candidates for extensions. To help you determine if your property is suitable, we offer feasibility visits.

A feasibility visit involves a thorough inspection of your home and surrounding area. We'll assess various factors, including:

Existing Structure

The condition and stability of your home's current structure will be evaluated.

Site Constraints

We'll consider factors such as property boundaries, easements, and any nearby structures that might impact the extension.

Planning Regulations

We'll review local planning policies to determine any restrictions or requirements.

Access and Utilities

We'll assess the accessibility of the site and the availability of utilities (e.g., water, electricity, gas).

Following the visit, we'll provide you with an email outlining our findings and recommendations. This will help you make an informed decision about whether a house extension is feasible for your property.

By choosing a feasibility visit, you can avoid unnecessary expenses and ensure that your extension project is a success. Contact us today to schedule your appointment.

Some Frequently Asked Questions

Do House Extensions Require Planning Permission?

When planning a house extension, one of the first questions to consider is whether you’ll need planning permission. In most cases, house extensions do require planning permission, especially if the extension significantly alters the size or appearance of your property.

However, there are exceptions. Some single-storey extensions may be considered permitted development, meaning they do not require formal planning permission. These exceptions are subject to strict rules, including limitations on the extension’s size, height, and proximity to property boundaries. For example, the extension must not extend more than a certain distance from the original rear wall of the house or exceed a specified height.

Expert Guidance on Planning Permission

Understanding whether your extension falls under permitted development or requires planning permission can be complex. Our architectural services include a detailed assessment of your project to determine the necessary steps and ensure your extension complies with all local regulations.

Do House Extensions require a Building Warrant?

Just like loft conversions, house extensions also require a building warrant. A building warrant is a legal document that authorizes you to carry out construction work. It ensures that your extension complies with building regulations and safety standards, protecting both you and your property.

Building regulations for house extensions cover a wide range of aspects, including:

  • Structural integrity: The extension must be structurally sound and able to support the additional weight.
  • Fire safety: Adequate fire protection measures must be in place.
  • Energy efficiency: The extension must meet certain energy efficiency standards to reduce heat loss and improve energy consumption.
  • Ventilation: Proper ventilation is essential to prevent moisture buildup and ensure good air quality.
  • Accessibility: If the extension creates new habitable rooms, they must comply with accessibility standards.

To obtain a building warrant for your house extension, you will need to submit plans and specifications to your local building standards department. They will review the documents to ensure that your project meets all the necessary requirements.

How long does it take to get a building warrant for an Extension?

The timeline for obtaining a building warrant for a loft conversion typically ranges between 12 to 16 weeks. However, this can vary depending on several factors, including:

  • Complexity of the project: If your house extension involves significant structural alterations, a structural engineer will be involved, which can extend the approval process.
  • Local authority workload: The workload of your local building standards department can also influence the processing time.
  • Any required revisions: If the building standards department requests revisions to your plans or specifications, this can add to the overall timeline.

It’s important to factor in potential delays when planning your extension project. By working closely with your architect and addressing any issues promptly, you can help to expedite the building warrant process and stay on schedule.

Certificate of Lawfulness: A Valuable Tool for House Extensions

A Certificate of Lawfulness is a document that can be obtained from your local planning authority to confirm that a particular use or development of land complies with planning law. While house extensions may often be considered permitted development, obtaining a Certificate of Lawfulness can still be beneficial.

Why Obtain a Certificate of Lawfulness?

Cost of House Extensions: A Breakdown

The cost of a house extension can vary significantly depending on several factors, including:

Size and complexity

Larger extensions, especially those involving structural alterations or multiple stories, will generally be more expensive.

Materials

The type of materials used, such as brick, timber, or steel, will affect the cost.

Design

More complex or customized designs can increase the cost.

Location

Geographic location can influence pricing due to factors like labor costs, material availability, and local regulations.

Permits & Fees

Planning permission and building warrant fees can add to the total cost.

Existing Structure

The condition of your existing home can impact the cost of the extension.

While it's difficult to provide a precise estimate without a detailed assessment of your specific project, house extensions typically range from £30,000 to £100,000 or more. Also always remember to add VAT!

It's important to consult with an architect or builder to get an accurate quote. They can assess your project's specific needs and provide a tailored estimate based on factors such as:

Scope of Work

The extent of the extension, including size, layout, and features.

Materials

The types of materials you prefer for the extension.

Labour Costs

The cost of labour will depend on your location and the complexity of the project.

Permits & Fees

The fees associated with planning permission and building warrants.

By working with a professional, you can ensure that you get a fair and accurate estimate for your house extension project.

When can I get a quote from a Builder for my project?

The ideal time to get a quote from a builder for your house extension project is after you have completed the design and planning stages and the building warrant drawings have been approved.

This ensures that the builder has a clear understanding of the scope of work, materials required, and any structural modifications needed.

Here's a breakdown of why this is the best approach:

  • Detailed Information

    Once the design and planning are finalized, you'll have detailed drawings, specifications, and a clear understanding of the project's scope. This information is essential for builders to provide an accurate quote.

  • Avoid Misunderstandings

    Having a well-defined project scope helps prevent misunderstandings or changes in scope that could lead to unexpected costs.

  • Competitive Quotes

    With a clear project outline, you can obtain quotes from multiple builders and compare their offers to find the best value.

By waiting until the design and planning stages are complete, you can ensure that you're getting a quote based on a well-defined project scope and avoid potential misunderstandings or cost overruns later on.

House Extensions - A Personalized Approach

While house extensions can be grouped together as a general project type, each individual project is unique and has its own specific characteristics. Factors such as the size of your property, the desired layout, and any planning restrictions will significantly impact the scope and cost of your extension.

To ensure that your house extension meets your exact needs and expectations, it's essential to work with an experienced architectural firm who can assess your specific situation and provide tailored guidance.
