Embarking on a home renovation journey in the South of England, in places such as East Preston, Worthing or Brighton and Hove entails contemplating the costs associated with various factors that can increase or decrease the overall cost of the project. For those considering a single or double storey extension, the investment is influenced by factors such as the extension's size, chosen materials, and the complexities of the renovation project.

Similarly, doing a loft conversion in these areas introduces a unique set of considerations, with costs varying based on design and the scope of improvements. Loft conversions, providing the opportunity to transform underutilized space into functional spaces, are also a significant aspect to ponder as this would help increase the value of your home.

Collaborating with professionals who understand the local context ensures that your envisioned extension or home renovation aligns not only with your aspirations but also with your budget and what can be allowed in the area where your home is located. While specific cost figures may vary, the journey toward a beautifully extended home is a collaborative effort, guided by your vision and the expertise of experienced professionals.

It's essential to consider factors such as the type of extension, its size, location, materials used, labour costs, and any additional features or complexities involved. Here are some key factors that influence the cost of building an extension:

  1. Type of Extension:

    • Single-storey extensions are generally less expensive than multi-storey ones.

    • Loft conversions and basement extensions have different cost considerations.

  2. Size of the Extension:

    • The larger the extension, the higher the cost. Costs are often calculated per square meter.

  3. Location:

    • The condition of the existing site can affect costs. For instance, excavation work or addressing challenging terrain may incur additional expenses.

  7. Permits and Approvals:

    • Costs associated with obtaining necessary planning permits and meeting building regulations should be considered.

  8. Utilities and Services:

    • Extending utilities (plumbing, electrical, HVAC) to the new space would contribute to costs.

Builders or construction professionals can assess your specific requirements and provide a detailed quote for your home project, however they would not be able to do so until your drawings are developed by your Architect.
