Bring Your Home’s Potential to Life
Thinking about moving? Let’s pause for a second. What if your current home already has the potential to give you everything you need? An extra bedroom. A bigger kitchen. A brighter, more open living space. You could have all of that - without the hassle of packing boxes.
​
We’re award-winning, RIBA-chartered architects based in Surrey. We take homes that feel tired or tight and turn them into something fresh, functional and truly beautiful. With smart design, we can often save you money and reduce environmental impact compared to moving house.
Should You Renovate or Extend?
Trying to decide between a renovation or extension? Here's a quick guide to help you make the right call:
Renovation - Want to keep the size of your home but completely change how it feels? A renovation is perfect if you're dreaming of a better layout, more light, or upgrading finishes. Great for kitchen makeovers, bathroom upgrades or full-house transformations.
Extension - Need more space? An extension lets you add square metres. Think: a new bedroom, a bigger kitchen, or a dedicated office. We design these to suit your lifestyle and handle the planning side for you.
Still unsure? We’re happy to talk it through and help you make the best choice for your home and your family.
