Maximize Your Home’s Potential with a Loft Conversion or House Extension

Looking to gain more space without the stress and cost of moving? A loft conversion or house extension offers a smart, cost-effective way to expand your living area and add long-term value to your home. Whether you’re unlocking the hidden potential in your attic or extending outward to create more room, these options give you the flexibility to shape your home around your lifestyle.

Imagine transforming your unused loft into a spacious master bedroom, a fun and functional kids’ playroom, a peaceful home office, or a welcoming guest suite. Alternatively, a ground-floor extension could provide the perfect open-plan kitchen-diner, a sunlit family room, or an additional bedroom for growing families. The possibilities are endless—and tailored to your needs.

Choosing the right contractor is crucial to achieving a high-quality result that stays within budget. With the right team by your side, your loft conversion or house extension will not only enhance the way you live, but also boost your property’s appeal and market value.

Whether you’re building up or out, expand your home with confidence—and invest in a brighter, more spacious future.

Loft and House Extension Combined Project "Vivanta smashed it — new loft, big kitchen extension, the works. The whole house feels brand new. They made everything super straightforward, kept things moving without any drama, and actually stuck to the plan. Proper legends — wouldn’t go anywhere else now. The glass installation was slick too — big roof panels and balcony done in-house. They were tidy, polite, and on point throughout. Communication was easy, updates were regular, and the project wrapped up exactly as promised. Zero stress, great finish, and solid people to work with. Highly recommend them." ⭐⭐⭐⭐⭐

Loft Conversion "Vivanta sorted our loft and it’s honestly changed the whole house. It feels massive now. They even built us a big glass balcony — looks amazing — since they do all their own glass manufacturing and installs too. They were super easy to deal with, kept everything clean, and actually listened to what we wanted. Nothing felt rushed, and the attention to detail was spot on. Their crew were friendly, on time, and really knew their stuff. Everything stayed on track, the finish is top class, and it’s added real value to our home. Couldn’t fault them — would use again." ⭐⭐⭐⭐⭐

House Rear Extension "Best decision ever getting Vivanta to do our extension. The space looks unreal and the whole job was way less hassle than we thought. They also did all the safety glass panels — we’ve even got a glass floor letting light down into our little gym in the basement — and the frameless glass conservatory looks insane. They cracked on with it, no dramas, and the finish is bang on. Everyone comments on it. The team was polite, skilled, and reliable. Everything ran smoothly from start to finish, and the result is better than we imagined. Top team — thank you!" ⭐⭐⭐⭐⭐
