Why More Homeowners Are Choosing to Extend
Across Widnes, Liverpool, and the North West, more homeowners are choosing to extend their homes rather than move. With property prices rising and the cost of moving increasing, a well-planned extension offers more space, added comfort, and long-term value without the upheaval of relocation. Whether it’s a kitchen extension, a new bedroom, or an open-plan living area, extensions can completely transform how a property feels and functions. But before a single brick is laid, there are several key things every homeowner should understand.
Understanding Planning Permission and Building Regulations
One of the first questions people ask is: Do I need planning permission?
The answer depends on the size, height, and position of your extension — as well as local council guidelines in Halton and Liverpool.
• Permitted Development Rights: Some smaller extensions fall under permitted development, meaning you may not need full planning permission. However, rules differ between semi-detached, detached, and terraced homes.
• Planning Permission: Larger or more complex builds will require an application to your local council.
• Building Regulations: Even if planning permission isn’t required, your extension must still meet building regulations.
Budgeting and Cost Planning
A clear, realistic budget is the backbone of every successful extension. Costs will vary depending on materials, layout, access, and finishes — but setting expectations early makes everything smoother.
Typical considerations include:
• Structural work: Foundations, walls, roof, and steelwork.
• Finishing materials: Windows, doors, plastering, and flooring.
• Plumbing & electrics: Especially important for kitchen and bathroom extensions.
• Professional fees: Architects, planning applications, and building control inspections.
Omnis Developments always recommend setting aside a 10–15% contingency for unexpected costs.

Designing for Practical Living
A well-designed extension isn’t just about square footage — it’s about how your home works for you.
Think about:
• Natural light: Roof lanterns, bi-fold doors, or large windows can make a dramatic difference.
• Flow and access: How will the new space connect to your existing layout?
• Energy efficiency: Insulation, glazing, and heating upgrades will reduce long-term costs.
• Future flexibility: Can the space adapt as your family grows or needs change?
Choosing the Right Builder in Widnes & Liverpool
Selecting the right team is the most crucial decision you’ll make.
Look for builders who:
• Have local experience with Halton and Liverpool building control departments.
• Can show previous extension projects similar to yours.
• Are fully insured and work to strict health and safety standards.
• Offer transparent quotes and communicate clearly at every stage.
Timescales: How Long Does It Take?
Every home extension is different, but most small to medium projects in Widnes and Liverpool follow a similar timeline:
Planning & design: 4–8 weeks
Groundworks & foundations: 2–3 weeks
Main structure: 4–6 weeks
Internal works: 3–4 weeks
Finishing: 2–3 weeks
Managing Disruption During Building Work
Even the best-managed projects bring some disruption. Dust, noise, and temporary access issues are unavoidable — but good planning can reduce the impact.
Tips to prepare include:
• Seal off work areas from living spaces.
• Use dust sheets and temporary partitions.
• Plan alternative access routes if possible.
• Communicate regularly with your builder to stay informed of progress.
Energy Efficiency and Building for the Future
Building regulations now place greater emphasis on energy efficiency. When extending your home, it’s worth investing in:
• High-performance insulation
• Low-energy lighting and heating systems
• Smart thermostats and efficient boilers
• Sustainable materials with low carbon footprints
