What Affects House Extension Costs?

Several key factors influence the cost of a house extension:

Size of the Extension

Larger extensions require more materials, labour and structural work.

Structural Requirements

Steel beams, foundations and structural openings all impact cost.

Ground Conditions

Certain areas of Poole may require additional groundwork depending on soil type.

Internal Finishes

Kitchen installations, flooring and finishing specification can significantly affect the budget.

Services & Utilities

Relocating drainage, plumbing or electrics can add to overall cost.

Cost Per Square Metre (Guide)

As a general guide:

  • £1,800 – £2,800 per m²

This can vary depending on specification and complexity, but provides a rough starting point when budgeting.

Planning Permission & Additional Costs

Some extensions fall under permitted development, but this depends on the property and size of the extension.

Additional costs to consider include:

  • Structural engineer calculations
  • Building control fees
  • Planning applications (if required)
  • Architectural drawings

Understanding these early helps avoid unexpected costs during the project.

Kitchen Extensions & Open Plan Costs

Many house extensions in Poole are designed to create larger kitchen and living spaces.

These projects often include:

  • Structural wall removal
  • Steel beam installation
  • Full kitchen renovation

As a result, kitchen extensions tend to fall into the mid to higher cost range.

Cost Considerations for Landlords & Investors

For landlords, house extensions may be used to increase rental value or improve layout.

This may involve:

  • Adding additional bedrooms
  • Improving usable space
  • Reconfiguring layouts

In some cases, extensions form part of wider renovation or HMO projects.

Balancing Cost & Value

When planning a house extension, it is important to balance cost with long-term value.

This includes:

  • Choosing practical layouts
  • Avoiding unnecessary complexity
  • Investing in key areas such as kitchens and living spaces

A well-planned extension can significantly improve both usability and property value.
