Expand your home with a bespoke extension
We enhance your property with well-designed extensions that create additional space for living, working or entertaining while improving overall value. O'Flynn Construction delivers single and double-storey extensions, along with kitchen and side return builds tailored to your home. We manage each stage from design through to completion with clear communication and your involvement throughout. As a family-run company, we also include internal fit-outs so your new space feels complete, practical and ready for everyday use.
A managed approach from the first visit to completion
At O'Flynn Construction, we keep the entire process straightforward by starting with a detailed site visit to understand your plans and guide you through planning requirements where needed. We handle material sourcing, scheduling and on-site coordination to maintain a steady workflow. With full insurance and FMB accreditation, we work with accountability and care at every stage. We provide clear timelines from the outset and keep you updated regularly, so decisions are made together with confidence. Our expertise also extends to new build homes, delivered with the same structured approach and attention to detail.​
Seamless integration for lasting home improvement
We create extensions that work naturally with your existing home, ensuring consistency in layout, structure and finish. Our focus is on improving how your space functions for family life, work or changing needs while supporting long-term value. Our process includes internal fit-outs, so the new area can be used immediately after completion. Every detail is completed with care so the finished space feels practical, comfortable and ready to live in from day one. Contact us to discuss your plans and take the next step.
