BBC Northern Ireland House of the Year – Winner
Long House / The Gallery was featured on BBC Northern Ireland’s House of the Year and selected as the overall winner.
Built around a 65-foot painting, the house creates a long, calm interior sequence of light, views and carefully framed spaces within a compact South Belfast site.

Long House
Long House was created for Bernard and Sinéad Jaffa on a backland site formed from part of their original property overlooking the River Lagan corridor in Belfast.
Planning permission for the house had already been secured before my involvement in the project. From that point onward, the design continued to evolve through close collaboration with the clients.
Bernard and Sinéad brought a strong vision for how they wanted to live. The house was never intended to be simply a container for rooms. It was conceived as a place for art, music, cooking, entertaining and everyday life, while remaining closely connected to the mature garden landscape that had been part of their lives for many years.
“It’s not just a house, it’s our home. It’s three years now and we haven’t gotten used to it. It’s an amazing feeling to wake up in. When we’re away on holiday we can’t wait to get home.”
— Bernard Jaffa, excerpt from BBC NI House of the Year submission, 2024
For me, that response from the owners is the clearest measure of the project’s success.
The House
The site falls significantly from one end to the other. This change in level gives the house much of its character, with lower, more enclosed spaces below and brighter, more open living spaces above.
From the lower level, the black concrete stair clearly invites you upstairs. Once there, it almost disappears from mind as the house opens into a bright double-height living space filled with garden views, artwork and daylight.
A key moment in this journey is the gradual appearance of a 65-foot-wide Neil Shawcross painting as you move upward through the house. Rather than being treated as decoration added after completion, the artwork forms part of the experience of moving through the building and helps anchor the main living space.
The upper floor is organised as a series of connected spaces rather than a collection of separate rooms. Large areas of glazing bring daylight deep into the building while framing views of mature trees beyond the site boundaries. The result is a house that feels open and spacious while still offering places for privacy and retreat.
Visitors describe the experience as being similar to a tree house. Living spaces sit among the surrounding canopy, enjoying sunlight, long views and a strong connection to nature while remaining firmly rooted in an urban setting.
Long House shows how a challenging site can become the starting point for a distinctive and deeply personal home. Through careful use of levels, light and space, the house feels considerably larger, richer and more connected to its surroundings than its footprint alone might suggest.

Plans, Sections & Concept Sketch
The house occupies a compact backland site, using its position and orientation to create privacy, sunlight and long views towards the garden and River Lagan corridor. Site plan.
The first floor is open-plan, with stairs, service spaces and wide windows subtly subdividing kitchen, living and bedroom areas while opening the house towards mature trees and the garden beyond. First floor plan.
Partly built into the fall of the site, the ground floor provides more enclosed accommodation below the open main living space above. Ground floor plan.
Changes in level, ceiling height and volume create a sequence of compression and release, culminating in a bright double-height living space organised around the clients’ 65-foot painting. Long section.
The stair is treated as a narrow, dark volume that compresses the route upward before opening into the taller, brighter main living space above. Cross section.
The house is organised as a series of rooms and service elements arranged as distinct volumes within a larger open-plan living space. Concept sketch.
