Understanding One Storey Extensions
When it comes to home extension planning, one storey extensions are a popular choice among homeowners due to their relatively straightforward construction process and potential to significantly improve a home's layout and usability without altering its overall height. Let's delve into the details.
Definition of a one storey extension
A one storey extension is an addition to a home that extends the existing footprint on one level, typically involving the construction of new walls, floors, and roofs. This type of extension is often preferred for its simplicity and cost-effectiveness compared to multi-storey additions.
Common reasons for adding a one storey extension
There are several reasons why homeowners often opt for one storey extensions. One of the primary reasons is cost-effectiveness. Compared to double-storey extensions, one storey extensions are generally less expensive per square meter, making them an attractive option for homeowners on a budget. Additionally, one storey extensions offer more design flexibility in terms of layouts and ceiling heights, allowing for open-plan living spaces and various room shapes. This design flexibility is particularly beneficial for families requiring wheelchair access or additional bedrooms without the need for complex structural changes.
Differences compared to multi-storey extensions
One storey extensions differ significantly from multi-storey extensions, which involve extending the home to include one or more additional floors. The primary difference between the two lies in their height and structural complexity. Multi-storey extensions require more complex foundations, structural work, and structural engineering, which can increase the cost and disruption to the homeowner's daily life. In contrast, one storey extensions are generally simpler in design and construction, making them more suitable for homeowners who want to improve their existing home without incurring significant costs or disruptions.
Overall, one storey extensions are a common and effective way for homeowners to improve their living space, enhance their home's layout and usability, and increase its value. With proper planning, design, and execution, a one storey extension can be a great addition to any home, providing a boost to the overall quality of life without the complexity and cost associated with multi-storey extensions.
Benefits of One Storey Extensions
When it comes to extending your home, one storey extensions are an increasingly popular choice for homeowners seeking to add valuable extra space without the complexity and cost associated with double-storey extensions. At its core, a one storey extension is an expansion of an existing home that extends the ground floor horizontally. This type of extension offers several benefits, making it an attractive option for those looking to enhance their living space.
Cost-effectiveness compared to double-storey extensions
One of the most significant advantages of one storey extensions is their cost-effectiveness compared to double-storey extensions. This is primarily due to the simpler construction process, which requires less structural work and foundation foundations. Studies suggest that one storey extensions are generally less expensive per square meter, with costs ranging between £1,500 to £2,400, making them a more affordable option for homeowners. This financial advantage is accompanied by the potential to save even more money with DIY options, which can be implemented during the construction process.
Simplicity of design and construction
In addition to their cost-effectiveness, one storey extensions also offer a high degree of design flexibility. The ground floor layout can be modified to suit the existing architecture and create an open-plan space. The horizontal extension style requires less disruption to the existing structure, making it easier to integrate the new extension without significantly altering the home's facade or disrupting the interior layout of the existing rooms. This flexibility in design makes one storey extensions suitable for various architectural styles and provides homeowners with ample opportunities to create a space that complements their existing home's aesthetic.
Less disruption during the build process
Another significant benefit of one storey extensions is the relatively less disruption they cause to the homeowner's daily life. Since the extension lies on the same floor as the existing structure, the construction process doesn't involve the same level of renovation as a double-storey extension. This results in reduced disturbance and the ability to maintain a relatively smooth workflow during the build process. Homeowners can still reside in their property during the construction, which is not feasible with double-storey extensions. These factors help to enhance the overall experience, making one storey extensions an ideal option for homeowners seeking to add extra space without significantly disrupting their lifestyle.
Planning and Permissions:
As you embark on designing and building your one storey extension, navigating the complex world of planning permissions can be daunting. But, by understanding the crucial planning permission guidelines and permitted development rights, you can ensure that your project is built to code and compliant with local regulations. Whether you're planning a modest addition or a substantial overhaul, this section will guide you through the planning application process, highlighting the design considerations and material choices that will integrate your extension seamlessly with your existing home, making it an extension that is truly greater than the sum of its parts.
Planning Permission Guidelines for One Storey Extensions
When it comes to one storey extensions, understanding the planning permission guidelines is crucial to ensure a successful project. In the UK, single storey extensions may require planning permission if they exceed certain dimensions, such as extending towards a road or increasing the overall height of the building.
To determine whether your one storey extension requires planning permission, you'll need to assess the size and location of the extension. If the extension is more than half the area of land surrounding the home, or if it extends towards a road, you may need to submit a planning application. Additionally, if your extension is higher than two storeys or larger than 8m in any direction from a detached house or 6m from an attached house, you'll likely need to obtain planning permission.
However, there are some permitted development rights that apply to single storey extensions. In general, these rights allow homeowners to build single storey extensions up to certain sizes and distances from the property's boundaries, without needing to obtain planning permission. For example, you can build a single storey extension that is 4m or more from the rear of an attached house, or 3m or more from the rear of a detached house. However, if your extension is larger than these allowed distances, or if it exceeds 3 storeys in height, you'll need to submit a planning application.
To navigate the planning application process, it's essential to gather all the necessary documentation, including your design plans, supporting images, and a written explanation of the extension's purpose and benefits. You'll also need to submit your application to the local planning authority, who will review it to determine whether the extension complies with local planning policies and regulations.
In addition to understanding the planning permission guidelines, it's also essential to consider the design of your one storey extension. The design should integrate with existing spaces, consider natural light, and use materials that match the original house. You can also utilize natural light and outdoor connections by incorporating features like large windows, sliding glass doors, and outdoor living spaces.
Criteria for Requiring Planning Permission
- Extending more than half the area of land surrounding the home
- Extending towards a road or a neighboring property
- Increasing the overall height of the building by more than 2 storeys
- Building a larger extension than the permitted development rights allow
- Building a second storey extension
Permitted Development Rights for Single Storey Extensions
- Building a single storey extension up to 4m from the rear of an attached house
- Building a single storey extension up to 3m from the rear of a detached house
- Building a single storey extension larger than 3 storeys in height
- Building a single storey extension that extends more than 6m from the rear of an attached house or 8m from a detached house
By understanding the planning permission guidelines and permitted development rights, you can ensure that your one storey extension is built to code and compliant with local regulations. Remember to also consider the design and layout of your extension to ensure it integrates with your existing home and meets your needs.
Design Considerations
When planning a one-storey extension, it's essential to consider the design to ensure that it integrates seamlessly with the existing home. This involves aligning the new extension with the original structure's architectural style, including the choice of materials, colors, and details such as molding and trim. By matching the existing design, the new extension becomes an extension of the home rather than an addition that stands out from the rest. This approach not only enhances the aesthetic appeal of the property but also creates a sense of continuity and cohesion.
Incorporating natural light and outdoor connections into the design can significantly enhance the functionality and livability of the extended space. This can be achieved by incorporating large windows, sliding glass doors, and skylights to take advantage of the available natural light. Moreover, designing the extension to seamlessly connect with the outdoors can create a harmonious transition between the indoor and outdoor spaces, ideal for alfresco dining, entertainment, or relaxation. This approach also fosters a deep connection with nature and promotes well-being.
Another critical factor to consider when designing a one-storey extension is the material choices. Matching the original structure's materials can help create a cohesive look and provide a smooth transition between the old and new parts of the home. However, it's also essential to consider the durability, maintenance, and sustainability of the materials used. This might involve incorporating locally sourced materials, such as reclaimed wood or brick, which can add character and warmth to the space while reducing carbon footprints. By prioritizing eco-friendly materials and energy-efficient solutions, homeowners can not only enhance the extended space but also contribute to a more sustainable future.
By focusing on integrative design, utilizing natural light and outdoor connections, and choosing materials that match the original structure, one-storey extensions can be transformed into seamless additions to the home, enhancing its livability, aesthetic appeal, and environmental sustainability.
Cost and Budgeting:
