Cost to Build a House

How much does it cost to build a new house?

Although building your own house can be considerably cheaper than buying from a developer or an existing house on the market, it’s still a significant investment. The increasing costs of land ownership, materials and skills shortage have reduced margins that were previously available.

However, embarking on a new build is an exciting venture, but understanding the costs involved is crucial for a successful build. The UK’s housing market is dynamic, and the costs associated with construction can vary significantly based on factors such as size, location, and design.

Below we’ve provided some ballpark figures for building different sized homes, and further down you can find prices submitted by WhatPrice users to give further insight into how much it can cost. You can also try our House Build Calculator for a rough estimate of build costs for various different sized homes.

Important Considerations:

  • Location: Costs can vary based on regional differences, with urban areas especially in the south generally being more expensive.
  • Quality of Materials: The choice of construction materials significantly influences costs.
  • Architectural Design: Unique or complex designs may incur higher expenses.

Understanding the average costs for different home sizes is a crucial step in the planning process. However, it’s important to note that these figures are general estimates, and individual circumstances, such as location and specific design choices, can influence the final cost. By delving into these details, you can embark on your home-building journey with a realistic budget and a clearer vision of what to expect along the way.
