Moss Hill delivers high-quality home extensions designed to expand living space, improve layout performance and increase long-term property value. Based in Crossgar, we undertake extension projects throughout Downpatrick, Ballynahinch, Saintfield, Comber, Belfast, Lisburn and surrounding areas.
Operating under a fully integrated Design & Build framework, we manage extension projects from early planning collaboration and architectural input through to structural construction and final completion. This ensures every extension is technically sound, structurally secure and professionally coordinated.

Rear and side extensions are among the most effective ways to transform existing homes. Whether creating larger kitchen-diner spaces, extended family living areas or open-plan layouts, we design and construct extensions that integrate seamlessly with the original property.
Our approach ensures structural stability, efficient sequencing and cohesive internal flow throughout the project.

Many extension projects involve removing internal walls to create open-plan kitchen and living environments. We coordinate structural reconfiguration, load-bearing wall removal and steel installation to support wide-span openings and modern layouts.
By combining extension construction with structural alterations, we deliver practical and contemporary spaces suited to modern family living.

For homeowners requiring significant additional space, double-storey and structural extensions provide long-term solutions. These projects require careful engineering, structural calculation and disciplined project management.
We ensure foundations, structural supports and roof integration are delivered with technical precision and full compliance oversight.
Successful home extensions require alignment between planning feasibility, structural design and build execution. We work closely with clients from the earliest stages to ensure extension layouts maximise available space while remaining structurally viable.
From site preparation and groundwork through to final finishes, all stages are coordinated within our Design & Build process to ensure smooth and controlled delivery.
Extension projects involve multiple trades, structural sequencing and careful scheduling. We manage contractor coordination, material planning and site operations within a defined construction programme.
From our base in Crossgar, we deliver extension projects across Downpatrick, Ballynahinch, Saintfield, Comber, Belfast and Lisburn with professional oversight and consistent quality standards.
