Frequently Asked Questions

How much value does a kitchen extension add?

A kitchen extension typically adds 10-18% to a property's value depending on the type. Wraparound extensions add the most value, while side return extensions offer the best ROI as they cost less relative to the value gained.

Is a kitchen extension a good investment?

In most London boroughs, a well-designed kitchen extension adds more value than it costs, making it a sound investment. The ROI is typically 1.2x to 1.8x, meaning you get back more than you spend.
