Leading specialists in Kitchen Extension Dublin projects, focusing on 40sqm exempted developments and high-spec, light-filled renovations.
In the heart of Dublin, from the historic red-brick terraces of Portobello to the sprawling semi-detached homes of Clontarf and Blackrock, the kitchen has always been more than just a place to cook. It is the "Heart of the Home"—the central hub where families gather, stories are shared, and memories are made.
However, many older Dublin homes suffer from a common architectural ailment: the "cramped, dark kitchen." Traditional Irish houses often feature small, compartmentalized kitchens that feel disconnected from the rest of the house and the garden. These spaces can feel gloomy even on the brightest Irish afternoons, struggling with poor layout and a lack of natural light.
This is where our bespoke Kitchen Extension Dublin service becomes transformative. We specialize in connecting homeowners with the finest house extension builders Dublin has to offer. Our "One-Stop-Shop" solution handles everything from design to BER certification.
Maximize your living space with our specialized project types.
We provide a comprehensive range of extension types, each tailored to the unique Dublin property landscape. Whether you are in a Victorian terrace or a modern semi-detached home, we have the expertise to unlock your home's potential.
Under Irish building regulations, most rear extensions up to 40 square metres (40sqm) are considered "Exempted Development." This means you can often build without the delays of a formal planning application.

Currently, a 40 sqm extension cost Ireland ranges from €80,000 to €120,000 for a high-spec, "turn-key" finish. This variation depends on factors like structural steel requirements and your choice of finishes (e.g., premium sliding doors vs. standard bifold doors). Dublin prices often sit at the higher end due to demand, but our fixed-price quotes eliminate surprises.
Under Exempted development Ireland regulations, you can usually build up to 40sqm to the rear without planning permission. Caveats apply: it cannot be higher than the existing house, and you must leave 25sqm of garden. Side-returns and multi-story extensions typically require permission. We provide a full feasibility check during our consultation.
While the extension itself isn't directly granted, you can avail of substantial SEAI grants for energy upgrades performed during the build, such as insulation and heat pump installation. This helps offset the cost of achieving a high BER rating (A-rated) for your home.
A standard Kitchen extension Dublin usually takes between 12 to 16 weeks on-site. The initial weeks involve groundworks, followed by the "watertight" stage (roofing and glazing), and finally the kitchen fitting and decorating. Modular options can reduce this time significantly.
Under Irish law (Planning and Development Regulations), you can extend your home up to 40 square metres (rear only) without planning permission, provided: 1. It's to the rear of the original house. 2. You leave 25sqm of private garden space. 3. The height doesn't exceed the original roofline. Side extensions always require planning permission. We handle all legal paperwork and compliance certifications.
In most cases, yes! We set up dust-proof partitions and ensure a safe, temporary kitchen setup if needed. However, during major structural wall removals (usually around week 4-6), some clients prefer to stay elsewhere for a few days due to noise and dust. We coordinate every step to minimize disruption to your family life.
We understand that a Kitchen Extension Dublin project in Blackrock is very different from one in Clontarf or Dalkey. Dublin's architectural diversity requires localized expertise.
Every builder in our vetted network is fully insured and carries local references you can trust.
