As each self-build home we work on is unique, the cost to build a timber frame house varies according to the individual specification.  When working out the build costs, we estimate that you could expect to spend anything between £225 and £275 per square metre of floor area. Obviously beyond construction costs there are a number of other costs which will need to be factored in, including how much work you plan to do yourself. We can discuss these further with you on initial enquiry.
