Two Storey Extensions Dublin & Across Ireland
At Top Builders Construction Ltd, we are experts in designing and building two storey extensions in Dublin and nationwide. For homeowners who want to maximise both ground and upper floor space without moving, a double-storey extension is the ideal solution.
A two storey house extension not only creates extra living space on the ground floor—such as an open-plan kitchen or family room—but also adds valuable bedrooms, bathrooms, or office space upstairs. At Top Builders, we specialise in extensions that are practical, stylish, and designed to integrate seamlessly with your existing home.
