A great start is to speak to an Architect to get a sense of the process, you can use online architectural fee calculators to answer the question how much does an architect cost
Plan for Contingencies: Reserve an additional 10-20% of your budget for unforeseen expenses.
3. Design Considerations:
Architectural Harmony: Assess the style of your current home to ensure the extension complements it. Whether you're aiming for seamless integration or a contrasting addition, the design should resonate with the existing structure.
Functionality Meets Aesthetics: Prioritize how the space will be used while maintaining an eye on design trends that might increase property value.
4. Regulatory Compliance:
Planning Permission: Determine whether your project falls under permitted development rights or if you need to apply for planning permission.
Building Regulations: Ensure your plans comply with building regulations, which cover structural integrity, fire safety, insulation, and more.
5. Professional Consultation:
Engage with architects or architectural designers who can provide expert guidance and help transform your vision into viable plans. For example, firms like us or other Worthing Architects specialize in creating custom residential designs that meld creativity with practicality.
6. Hiring Contractors:
Source reputable builders and tradespeople. Request quotes, check references, and review previous work to ensure quality craftsmanship.
7. Detailed Drawings and Specifications:
Work with your architect or designer to prepare detailed plans that will guide construction and serve as part of the application for regulatory approvals.
8. Securing Permissions:
Submit applications for planning permission if required, along with any necessary building regulation approvals before commencing work.
9. Construction Phase:
Oversee the project through its construction phase, ensuring that work adheres to plans and stays within budget.
Regularly communicate with your builder to address any issues promptly.
10. Finishing Touches:

Importance of Architectural Design
The architectural design is not merely about aesthetics; it's about integrating the new structure into the fabric of the existing house both functionally and visually:
Respecting Original Features: If you have a period property or unique architectural elements, it's crucial to respect these in your extension design.
Material Choices: The materials used can either contrast or complement the existing home, depending on whether you want the extension to stand out or blend in.
Proportion & Scale: The size of the extension should be in proportion to the original house to maintain balance.
Natural Light Considerations: Introducing natural light through strategic placement of windows, skylights, or glass doors can transform internal spaces.
Flow Between Old & New: Ensure there is a logical transition between existing rooms and new spaces created by the extension.
By appreciating these factors during planning stages, you'll create an extension that doesn't just add square footage but also
Special Considerations for Different Types of Houses
When considering an extension to a listed building, homeowners must navigate a unique set of challenges and regulations. Listed buildings are protected due to their historical significance, and any changes must be carefully managed to preserve their character.
Understanding Listed Buildings and Listed Building Consent
Listed buildings are catalogued because they have particular architectural or historic interest. In the UK, these buildings are classified into Grades I, II*, and II, with Grade I being the most significant. Extending or altering a listed building requires Listed Building Consent from the local planning authority. This consent ensures that the special interest of a listed building is not compromised by any alterations.
The Journey to Extend a Listed Home
Step 1: Research and Understand Your Building's Significance
Historical Research: Investigating the history of your home can provide insight into its significance and guide your extension design in a way that respects its heritage.
Consult Local Records: Planning authorities maintain records of all listed buildings, which can be invaluable for understanding any previous alterations or conditions.
Step 2: Pre-Application Advice
Engage with Your Local Planning Authority: Many authorities offer a pre-application advice service where you can discuss your proposals before submitting a formal application.
Seek Professional Guidance: Architects or surveyors who specialize in heritage buildings can advise on how best to approach your project.
Step 3: Design Considerations
Sympathetic Materials and Methods: Using materials and construction methods that match or complement the existing structure is essential.
Visibility: Any extension should not dominate the original building but rather complement it.
Step 4: Submitting Your Application
Detailed Plans: Provide detailed drawings and plans that clearly show how the extension will look in context with the existing building.
Supporting Documents: A statement of significance and a heritage impact assessment often accompany applications for listed buildings.
Step 5: Navigating the Decision Process
Public Consultation: Applications may be subject to public scrutiny, so it’s important to be prepared for feedback from the community.
Challenges Specific to Listed Buildings
Extending a listed building presents several distinctive challenges:
Structural Concerns: Older buildings may have structural limitations that could restrict extension possibilities.
Preserving Character: Any extension must preserve or enhance the building's character, requiring careful design consideration.
Balancing Modern Needs with Historic Preservation
Owners of listed buildings often seek to balance modern living needs with preserving history:
Contemporary Additions: Glass structures are sometimes used to contrast yet complement historic fabric.
Sensitive Integration: Incorporating modern facilities without compromising historical features is key.
Regulations Impacting Extension Projects
Listed Building Consent is specific to alterations on listed properties; however, other regulations may also apply:
Planning Permission: Depending on the scale of the work, planning permission might still be required in addition to Listed Building Consent.
Building Regulations: All extensions must comply with current building regulations regarding safety, energy efficiency, and accessibility.
Cost Implications
Extending a listed home often involves higher costs due to:
Specialist Materials: Heritage projects may require specific materials that are more expensive than standard ones.
Tips for Successful Listed Building Extensions
To ensure success when extending a listed property:
Engage specialists early in your project.
Be prepared for a longer planning process due to additional scrutiny.
Budget for unexpected costs associated with working on older structures.
In summary, extending a listed building is complex but entirely feasible with careful planning and expert guidance. Embracing the distinctive challenges will ensure that both the historical value of your home is preserved and its future as a comfortable living space secured.
Securing Permissions and Ensuring Compliance
When you're planning a house extension, it's important to understand the rules and regulations that apply. Two main things to consider are Planning Permission and Building Regulations.
Understanding Planning Permission Requirements
Planning Permission is all about how your extension will impact the local area and your neighbours. In some cases, you may not need planning permission for small extensions, but it's always a good idea to check with your local planning authority to be sure.
Here are some things to keep in mind:
Permitted Development Rights (PD): Certain types of extensions can be done without explicit planning permission. For example, single-storey rear extensions up to 4m for detached houses and 3m for other houses.
Designated areas: If your home is in a special area like a National Park or an Area of Outstanding Natural Beauty, or if it's a listed building, you'll usually need planning permission even for extensions that would normally be allowed.
Multi-storey extensions: If your extension will have more than one floor, it's likely that you'll need planning permission.
You can find more detailed information on whether your extension requires planning permission by visiting the Planning Portal.
The Importance of Building Regulations
Building Regulations are different from planning permission and focus on making sure that any construction work is safe, energy-efficient, and accessible. They usually apply to most types of building work.
Here are a few key points about Building Regulations:
Full plans application: This involves submitting detailed plans of your proposed work to the local authority for approval before you start construction.
Building notice: For smaller projects, you can choose to give a building notice instead of submitting full plans. This lets the local authority know about the work in advance.
To ensure compliance with Building Regulations, it's essential to stay up-to-date with the latest legislation changes. Worthing architects and construction professionals can refer to this comprehensive guide: New Building Regulations: A Guide for Worthing Architects.
Considering the Costs
It's worth noting that there may be additional costs involved in getting the necessary permissions. In England, applying for planning permission typically costs around £206, while a full plans application for building regulations approval can range from £200 to £840 depending on the complexity of the project.
Here are some tips to help you manage these costs:
Check permitted development rights: If your extension falls within the limits of permitted development, you might be able to avoid the expenses associated with planning permission.
Do-it-yourself applications: While it's recommended to seek professional guidance, you have the option to save money by handling the applications yourself.
Budget ahead: Take these costs into account when planning your budget from the beginning so that you're not caught off guard later on.
