We collaborate closely with clients, property agents and lead contractors to bring your vision to life while staying on budget and on schedule.

Our history

Our founder, Nikolay, brings over 15 years of hands-on experience in delivering exceptional home renovations, extensions, and structural work. With a background in small- and medium-scale construction projects, Nikolay recognised a growing need for a trustworthy, client-focused construction company—one that prioritizes clear communication, cost efficiency, and superior workmanship.

Areas we cover

Based in Sutton, South London, we started as a local construction business dedicated to helping homeowners reimagine their spaces. Over time, our reputation for quality, reliability, and personalised service has allowed us to expand our reach across London, Surrey, Bognor Regis, and the South East. Today, E21 Construction is a trusted name in the industry, known for delivering projects that combine structural integrity with aesthetic excellence.
