Overview

• Nationwide reports that adding a loft conversion or extension with a large double bedroom and bathroom can lift a typical three-bedroom, one-bathroom home’s value by up to 24%, about £65,279 on a £271,995 property.
• The analysis estimates an extra bedroom adds around 13% to value, an extra bathroom about 4%, and a 10% increase in floor area roughly 5%.
• A Censuswide survey for Nationwide finds most renovators focused on kitchens and bathrooms, while only 24% pursued loft conversions and 21% built single-storey extensions.
• Average spend among homeowners who renovated in the past five years was roughly £52,000, rising to around £97,000 for those aged 25 to 34.
• About a third of renovators made green upgrades and 56% of that group added solar panels, as industry bodies advise checking planning rules, listed status and conservation-area restrictions before major works.
