Nathan Emerson, its chief executive, said: “With an ever-growing population comes a defined commitment to ensure there is a sustainable mix of new dwellings to keep pace with future demand.
“Across all nations, various governments have made key pledges to build ambitious numbers of new properties. However, it remains prudent to ensure such homes are designed and built to deliver realistic affordability and better certainty regarding long term pricing trends.
“While the price of raw materials and labour generally trends upwards over time, from a consumer viewpoint, it can appear puzzling to see such year-on-year price fluctuations on new homes coming to the market.
“It is important to consider house pricing is influenced by many complex metrics, which may include the initial cost of the land any such properties are built on, the type of property being constructed, the cost of design, and the intricacies of the planning approval process, as well as the availability of base materials at any particular time, to credit just a few considerations.”
