Transform Unused Space with a Garage Conversion or Garden Studio
Want to add functional living space without the hassle of a full extension? A garage conversion or bespoke garden studio is a smart, affordable way to upgrade your home—no planning permission needed in most cases. Whether you’re after a home office, bedroom, gym, utility, or guest suite, Vivanta helps unlock the potential of underused space. Garden studios offer modern comfort, privacy, and the perfect environment for remote work or creative pursuits. We handle everything—from planning and insulation to electrics, plumbing, and finishing—delivering high-quality, regulation-compliant results. Attached or detached, our designs blend seamlessly with your home and lifestyle. A single garage (15m²) conversion in London typically costs from £13,000–£20,000, while a double (30m²) can range £23,000–£35,000.
With Vivanta, your unused space becomes your most valuable asset.
