Understanding Base Costs vs. Total Investment

When venturing into new construction territory in the UK, it’s crucial to understand that the advertised base price is just the beginning.

Recent data from the National House Building Council (NHBC) indicates that the average new-build house price in the UK reached £378,000 in early 2024, representing a 3.2% increase from the previous year.
