Some of Our Work

Modern two-story house with a brick and white exterior, large windows, and a spacious patio with outdoor seating, surrounded by a green lawn and trees.

bushy park gardens

Rathgar | Dublin

Dating to the 1920s, this Rathgar, Dublin 6 house was extended and remodeled for a family with free-flowing spaces. The architects linked existing and new areas seamlessly. The extension matches the original rooms in scale, blurring indoor and outdoor boundaries to include garden views. A black timber canopy shelters a patio, enabling covered outdoor living and smooth indoor-outdoor flow. The new brick terrace echoes the house’s materials, serving as a base for the extension and connecting inside to garden.

Two large roof lights with white timber joists diffuse soft overhead light. A steel and timber canopy provides seating and dining outdoors. From the entrance, the extension frames a view of the garden, blurring the line between inside and outside and bringing nature into the space.

carlisle mews

Bray | Wicklow

The project focused on transforming two coach houses located on a mews lane in Bray, Co. Wicklow, along with adding a charred timber-clad extension at the rear. Originally constructed in the mid-1800s as stables for the main residences on Duncairn Lane, the coach houses were repurposed in the 1940s for industrial workshops. After acquiring the site in late 2020, the clients aimed to convert the structures into a family home. The architects prioritized preserving the historic character of the original buildings while ensuring a comfortable and spacious living environment. Through comprehensive retrofitting and enhancements to the existing fabric, combined with the new extension, the project successfully achieved a BER rating of A2.

Edwardian House

South County Dublin

This Edwardian house in South County Dublin has been beautifully extended and transformed. A bespoke kitchen and seating area serve as the heart of daily life, creating a seamless connection between spaces and ensuring a natural flow throughout the ground floor.
The extension effortlessly opens to the garden. The original rear reception room has been reimagined as a tranquil retreat, linked to the kitchen and extension by elegant glazed steel-framed doors.
The rich dark oak finishes contrast beautifully with the warm marble surfaces, while the soft textured walls and tactile elements add depth and comfort. Every detail has been thoughtfully designed, resulting in a refined and inviting home where light, space, and materials blend harmoniously.

Sustainable Residential Design

We believe that high-end design and environmental responsibility are inseparable. Our approach to sustainable architecture focuses on the "Fabric First" principle—prioritizing high-performance insulation, airtightness, and natural light to create homes that are as healthy as they are efficient.

As experts in NZEB (Nearly Zero Energy Building) standards, we integrate renewable technologies like air-to-water heat pumps and MVHR systems seamlessly into contemporary aesthetics. Whether it’s a new build or a deep retrofit of a period home, we design for longevity, reduced carbon footprints, and ultimate thermal comfort.
