Stage 1: Initial Ideas and Design For your Extension
The first stage of a residential extension project is all about developing your ideas, and creating a clear design concept. Here's what you should consider:
Assess Your Needs: Identify why you want the extension and what it will be used for. This could be extra living space, a home office, or a bigger kitchen.
Budget: Establish a realistic budget. Your budget will significantly impact the design, materials, and scale of your extension. Please see our link to extension prices.
Design Brief: Develop a design brief that outlines your requirements, preferences, and any specific features you want in your extension.
Architectural Designer/Architect: Hire an architect or architectural designer to help you create detailed plans and drawings that meet local regulations. Designers and architects will help you get the most from your space, listen to your budget requirements and help you plan the house to meet your needs. They usually push you to think outside the box and challenge your ideas using design tricks to maximise space and light.
Planning Permission: Some extensions may require planning permission. Your designer will advise you on whether this is necessary, sometimes you can build extensions and home offices without planning permission using the permitted development rights.
Stage 2: Planning Permission
Should your scheme require planning permission, this process involves several elements:
Application Submission: Your architect or designer will help you complete and submit the planning application to your local planning authority.
Consultation: Local authorities may consult with neighbors and other consultants to gather feedback and this aid the planning officer in making a decision..
Decision: The authority will either grant or refuse permission. If granted, they may impose specific conditions which may require extra applications to ensure compliance.
Appeal: If your application is rejected, you have the option to appeal the decision.
Stage 3: Building Regulations
Once planning permission is secured, it's time to address building regulations. These regulations ensure that your extension meets safety and current Building Regulation Standards. Key steps include:
Building Control Officer: Appoint a building control officer, either from the local authority or a private firm, to oversee compliance. The Architect or Designer will be able to inform you on your choices.
Detailed Plans: Provide the officer with your architectural plans and details of the project for review. The Building Control department will then check the plans against current Building Regulations and issue an initial report, at this stage any amendments to the plans can take place prior to commencement on site.
Inspections: Regular inspections will be conducted during construction to ensure compliance. Building Control will give you and the builder a list of the stages for inspection.
Completion Certificate: Once the project is finished, the building control officer will issue a completion certificate if everything meets regulations.
Stage 4: Construction
With planning permission and building regulations in place, it's time to begin construction. Choose a reputable builder and monitor the project's progress:
Contractor Selection: Select a builder or contractor based on reputation, experience, and recommendations.
Project Management: Regularly meet with your builder to ensure the project stays on schedule and within budget.
Quality Control: Maintain a high standard of workmanship throughout the construction process.
Inspections: Cooperate with building control officers during inspections to address any issues promptly.
Stage 5: Completion and Handover
As the construction phase draws to a close, it's time to wrap up the project and hand over your newly extended home:
Snagging: Identify and rectify any minor issues, known as "snags," before the final handover.
Certification: Ensure that all compliance certificates are in order.
Final Payment: Make the final payment to your builder once all work is completed and to your satisfaction.
Enjoy Your New Space: Finally, you can start enjoying your expanded and improved living space.
