Construction Company in Southampton, Hampshire.
KA Builders Home Improvement
At KA Builders Home Improvement, we understand that every home tells a story — and we’re here to help you shape it. As a long-standing construction company in Southampton, we’ve built our name not just on the structures we create, but on the trust and satisfaction of the homeowners we serve. With a focus on home extensions, kitchen renovations, and bathroom improvements, our goal is simple: to deliver spaces that are beautiful, functional, and built to last.
What makes us different is how we operate. Unlike many companies that subcontract work, we offer fully all-in-one building services in Southampton — managing every stage in-house to ensure consistency, quality, and accountability. From landscaping services to driveway installations, plastering and decorating, and custom carpentry services, we eliminate the hassle of hiring multiple trades. Our clients enjoy a seamless process led by a team that communicates clearly, works efficiently, and treats every home with respect.
But beyond the bricks and tools, we’re a company built on people. We’ve proudly served the Southampton area for over 18 years, forming lasting relationships with clients who return again and again. We’re not just completing projects — we’re improving lives through better spaces, fair pricing, and unwavering honesty. Whether you’re searching for kitchen renovation near me or planning your dream extension, KA Builders brings experience, care, and community values to every job we take on.
