Whether you're replacing an existing property or building on a new plot, understanding the costs involved helps you plan effectively and avoid surprises. This guide breaks down the key factors that influence [new build costs in Brighton](/services/new-builds) for 2025. ## Average New Build Costs in Brighton In 2025, new build costs in Brighton typically range from £1,800 to £3,000+ per square metre, depending on specification. A standard three-bedroom detached home of approximately 120m² could cost between £216,000 and £360,000 for the build alone, excluding land purchase and professional fees. These figures reflect the unique challenges of building in Brighton, including restricted access in terraced streets, conservation area requirements, and the premium on skilled tradespeople in the South East. ## Key Cost Factors ### 1\. Site Preparation and Foundations Brighton sits on chalk downland, which generally provides good load-bearing capacity. However, some areas—particularly near the seafront or in valleys—may require more complex [foundation solutions](/services/foundations) such as [raft foundations](/services/raft-foundations). Ground conditions significantly affect costs, with difficult sites adding £15,000–£40,000 to the budget. ### 2\. Planning and Design Planning permission in Brighton & Hove can be more complex than other areas due to conservation zones and the South Downs National Park boundary. Architectural fees typically run 5–10% of the build cost, and you should budget for structural engineer reports, building control fees, and party wall agreements where applicable. Read our [planning permission guide](/blog/planning-permission-guide-east-sussex) for more detail. ### 3\. Materials and Specification Material choices have the largest impact on per-square-metre costs. A basic specification using standard fittings will sit at the lower end, while premium finishes, underfloor heating, and bespoke joinery push costs upward. Supply chain stability has improved since 2023, but early procurement is still advisable for specialist items. ### 4\. Labour Costs Brighton's construction market is competitive. Skilled tradespeople command premium rates, reflecting the high cost of living in the city. Working with an experienced [building contractor](/about) who manages subcontractors effectively can help control costs and maintain quality throughout the build. ## How to Control New Build Costs - **Fix your specification early** — Changes during construction are the most common cause of budget overruns. - **Choose your contractor carefully** — Look for experience with Brighton projects and transparent pricing. Read our [customer reviews](/reviews). - **Plan for contingency** — A 10–15% contingency is standard for new builds. - **Consider phased builds** — Some elements can be deferred to manage cash flow. ## Foundation Types and Their Impact on Cost The type of foundation your new build requires significantly affects the overall budget. Standard [strip foundations](/services/foundations) are the most economical option, while [raft foundations](/services/raft-foundations) are necessary on sites with poor or variable ground conditions. Read our detailed comparison: [raft foundations vs strip foundations](/blog/raft-foundations-vs-strip-foundations). ## Why Choose Masters Group for Your New Build?
