What was the cost of Building a New House in Woodside,Wigmore in 1939?

My grandparents purchased a plot of land in Woodside in 1939 to build their own property when the whole area was being sold as individual plots for people to build on. The construction began in July 1939 and was completed in March 1940 despite the war starting and my grandfather being called up.

The invoice from the builder for constructing their bungalow is shown below. There are not many houses that you could build for £430 now! Bear in mind this was just the house building and the plot was purchased separately. You can read about the sale of plots across the area here Wigmore Estate Plans from 1912
