With The Clever Construction Company, you can upgrade your living space with a Guardian Home Extension — an energy-efficient, beautifully open-plan solution tailored to your home. Built using factory-precision components and advanced methods, your extension can be completed in less than half the time of a traditional build, and with far less disruption.
Whether you’re looking to add a larger kitchen-diner, a bright family space, or a quiet retreat, the Guardian Home Extension lets you maximise your home’s potential and design something that truly fits your family’s needs.
Explore the range of Guardian Home Extensions — with five unique styles, finishes, and layouts to help you picture the perfect space for your home.
Social+ opens up kitchen, dining and living into one flowing area designed for hosting. Wide-span bi-fold doors and the slimline Guardian Roof Lantern maximise light and sightlines, giving you a stylish, sociable hub for family dinners, parties and everyday living.
A light, quiet extension designed for creative work, studio projects or a professional home office. Creative+ creates a clear separation between living and working space so you can focus without distractions — ideal for remote working, artists or makers who need a peaceful, purpose-built environment.
Rest+ provides a self-contained, well-proportioned sanctuary attached to the main house — great for an elderly relative, young adult or multigenerational living. Wide double doors connect to the garden for light and independence while keeping the comfort and reassurance of home-close living.
Bright, airy and adaptable, Play+ is perfect for busy family life. Large glazed doors and a Guardian Solstice skylight flood the room with natural light, creating a safe, open area where kids can play and the whole household can relax. Versatile finishes let you change the room’s function as your family grows
Utility+ is a functional lean-to extension that reclaims cluttered rooms and creates an organised, comfortable space for laundry, boot-room, pantry or extra storage. It’s a straightforward, cost-effective way to improve household flow without compromising style.
