Build Costs

Understanding the full cost of your self build project is key to ensuring a successful build. As well as the material cost of your build and the level of specification required there are various other factors to consider, issues such as ground conditions, access to the site, location and proximity of services etc. are a huge factor in the build budget and in establishing all of the costs. Selfbuildplans are predominately a design consultancy, however our other company can provide a full tender of all works for your consideration.
Please contact us for further information.
Homebuilding & Renovating magazine in conjunction with the RICS produce a comprehensive webpage here that provides current information on build costs and is a good starting point.
There are other resources on the web which we list here:

A breakdown of the costs have been kindly provided from MGD Building Cost Services and are listed below as a real example:

    The site had an existing bungalow that required demolishing and several trees.
    The services connection costs are low due to the site having existing services ready for connection and generally the cost would be around £3,500k.
    The build was a traditional brick and block cavity wall construction with traditional joists and trusses.
    Please remember that the above costs are the actual costs for this build and your own costs may vary.
