We Build Beyond Expectations
Ascent Builders specialise in high-quality loft conversions, home extensions, and plastering & decorating services.
That idle space above your ceiling is full of potential. We can transform your dusty attic into a home office, an extra en-suite bedroom, a home cinema, or anything else that would improve the enjoyment of your home. Our experienced team always delivers stunning, high-quality finishes to bring your vision to life.
That bit of garden you barely use? It’s hiding your dream space.
We can turn it into a bright new kitchen, a bigger living room, or a playroom. Whatever you need — more space, better flow, room to breathe — we’ll build it with care, precision, and the kind of finish that makes it feel like it was always meant to be there.
That patch of lawn could be so much more than a place to push a mower around. We build detached garden offices that give you space to focus, think, and work — without the kitchen table chaos.
Whether you want a sleek home studio, a quiet therapy room, or just somewhere to get things done, we’ll build it properly, from the ground up, with style and a structure that lasts.
Worn-out spaces, outdated finishes, or tired-looking rooms? We transform them. Our renovations and refurbishments deliver clean, modern, and long-lasting results. Whether it’s a single room update or a full property makeover, we leave every detail flawless — ready for living, working, or simply being admired.
