Side Double Storey Extension and Rear Single Extension
Side Double Storey Extension & Rear Single Storey Extension – A Seamless Home Transformation
This project is a prime example of how J&J Group Build Solutions turns vision into reality through thoughtful planning, precise execution, and quality craftsmanship. The client wanted to maximise their living space without compromising on flow, light, or style—so we delivered a fully integrated Side Double Storey Extension along with a Rear Single Storey Extension, blending perfectly into the existing structure.
What We Delivered:
Side Double Storey Extension:
This two-storey addition expanded the home vertically and laterally, creating room for a new bedroom and en-suite upstairs, while extending the ground-floor living and dining areas. The new structure mirrors the architectural lines of the original building, preserving aesthetic continuity.
Rear Single Storey Extension:
At the back, we built a spacious ground-level extension that now houses a modern open-plan kitchen, with direct access to the garden via full-width bi-folding doors—flooding the space with natural light and creating a true indoor-outdoor flow.
The result is a spacious, modern home tailored to the family's lifestyle—more functional space, better flow, and added property value, all completed on time and within budget.
From concept to completion, our team managed every aspect of the build, including groundworks, structural work, electrical and plumbing installations, and final finishes.
