Whats involved in the cost of house extensions?

Understanding House Extension Costs

Finding out how much your house extension will cost, involves many factors. Expanding your home is a significant investment, especially in prestigious areas like Hampshire, Surrey, and London. This guide will help you understand the costs involved in house extensions, ensuring you make informed decisions that enhance your property’s value and functionality.

When planning a house extension, several factors influence the overall cost. Here’s a breakdown to help you estimate expenses accurately:

House Extension Cost Calculator

To get a rough estimate of your project, consider the following formula:

Extension Cost = (Square Meters × Cost per m²) + Additional Costs

For instance, in Surrey’s exclusive Virginia Water:

Size: 40m²
Cost per m²: £2,000
Additional Costs (planning, design): £15,000

Estimated Cost: (40 × £2,000) + £15,000 = £95,000

House Extension Cost per m²

Costs vary based on location and the quality of materials used:

Hampshire: £2,000 – £3,000/m²
Surrey: £2,500 – £3,500/m²
London: £3,000 – £4,000/m²

In affluent areas like Notting Hill or Kensington, expect costs at the higher end.
