A house extension is a fantastic way to create more space, increase your property’s value, and design a home that works for your lifestyle. If you're considering a house extension in Liverpool, one of the most common questions is: How much will it cost?


The cost of a house extension can vary significantly depending on factors such as size, design, materials, and location. This article breaks down the costs associated with house extensions in Liverpool to help you plan your project and budget effectively.


Factors That Affect House Extension Costs in Liverpool

Before diving into specific numbers, it’s important to understand the key factors that influence the cost of your house extension:


1. Size of the Extension

  • The larger the extension, the higher the cost. Extensions are typically priced per square metre, with larger projects requiring more materials and labour.
  • Expect costs to range between £1,500 and £2,500 per square metre for a standard single-storey extension.


2. Type of Extension

The type of extension you choose significantly affects the cost:

  • Single-storey extensions: More affordable and ideal for kitchens, dining areas, or living rooms.
  • Double-storey extensions: Cost-effective for adding extra bedrooms and bathrooms, with only minimal added cost for the second floor.
  • Side return extensions: Popular for narrow properties like Victorian terraces but can require structural changes.
  • Wraparound extensions: Combine rear and side extensions, offering maximum space but with higher costs.


3. Materials and Finishes

  • The choice of materials for walls, flooring, roofing, and windows can dramatically change the price.
  • Premium finishes such as bespoke kitchens or hardwood floors will increase costs, while more budget-friendly options can keep the price lower.


4. Labour Costs

  • Labour is one of the biggest expenses, with experienced builders and tradespeople ensuring high-quality workmanship.
  • In Liverpool, labour costs for house extensions are generally competitive, averaging £200-£250 per day per tradesperson.


5. Planning Permissions and Regulations

  • While many house extensions fall under permitted development, larger or more complex designs may require planning permission.
  • Factor in costs for architectural drawings (£1,000–£3,000) and structural engineers (£500–£1,500).
