We have developed four different sophisticated cost per square metre calculators – one for extensions, one for loft conversions, one for refurbishment projects and one for new builds, and all of them updated for 2020 price per square metre build cost prices. While every project is unique and it is impossible to give an accurate price without tender and construction drawings, using these build cost calculators will give you a sense of what you need to budget for your project.
Just pick the construction cost calculator below that matches the type of project you are considering. Put in the basic details of your scheme and it will quickly calculate the build cost of your extension, loft conversion, refurbishment or new build house. The whole process takes just 30 seconds. Best of all, it will give you the insight you need at the preparation and planning permission stage of your project.
The estimated build cost shown below will give a very good indicator of the likely costs for building or refurbishing your project – but do remember it is always possible to further save on these costs by planning ahead, engaging a well-established residential architecture company and choosing the right builder.
Based on years of practical experience with builders, the proven steps we’ve set up and the hands-on construction inspection approach we’ve developed, we can help you avoid any possible issues that may arise onsite. That way, you can build your project with minimum stress, complete your project on time and avoid budget blowouts.
The build cost will depend on several variables including the complexity of the design, extent of structural works and level of fixtures, fittings and material finishes. Always ask your architects to conduct due diligence on your timescale and budget considerations.
