In Grantham, homes come in all shapes and sizes, from characterful Victorian terraces to 1930s semis and modern new builds on the edge of town. But even the most charming property can start to feel cramped over time. If your home no longer works for you, a carefully designed home extension could be the perfect solution.
At Construction Interior Design Ltd, we specialise in bespoke home extensions in Grantham and the surrounding areas. With over 30 years of hands-on experience, our team combines thoughtful design with practical construction know-how, creating extensions that feel like a natural part of your home. Whether you’re dreaming of a bright kitchen-diner, a new bedroom, a home office, or a space for family life to flow more easily, we’ll bring your ideas to life, without the upheaval of moving.
Why settle for a house that no longer fits your lifestyle when you can extend it into one that does? An extension is more than extra square footage – it’s an investment in comfort, flexibility, and the long-term value of your Grantham home.
We know no two households are the same, so why should extensions be one-size-fits-all? Our projects are built around your needs, budget, and vision. Whether for domestic or commercial spaces, every extension is designed to blend seamlessly with your existing property. Here’s what makes an extension worthwhile:
Personalised space – designed to suit how you live, work, and relax.
Better layouts – open up smaller rooms into bright, flowing spaces.
Added value – particularly in popular towns like Grantham, extensions can make your property more attractive to buyers.
Seamless design – carefully matched to your home’s character and style.
