New Build

New House Delgany

Delgany |Wicklow |2013-2014

Our clients had a timber-frame dormer bungalow on a 1.1-acre plot on the site in County Wicklow. By selling it and half of the plot, they were able to build an A-rated house on the remaining land. The clients were looking for a modern, energy-efficient house with plenty of glass to bring light into the building.

We wanted the house to take advantage of the stream, which ran close to the house along the eastern boundary of the site. The understated curves of the design mirror the natural curvature of the stream, whose waters babble underneath an overhanging balcony on the ground floor with a view towards an existing secret garden.

From the front, our house design building looks more imposing than it actually is. In fact, because so much of the downstairs is open plan, there are only four rooms on the ground floor. There is a large kitchen-cum-dining room that has a “relax area”, a formal living room, a utility room and a guest lavatory. Upstairs, there are four bedrooms, two of which have en-suite bathrooms. One has a walk-in wardrobe and there is also a family bathroom. On the eastern side of the house, there are two cantilevered balconies, fanasticone above the other. The upper balcony, which is reached via the master bedroom, doubles as a canopy for the larger balcony below. The lower balcony is reached via sliding doors to the side of the kitchen. These doors form part of a six-metre wide window, which brings morning light flooding into the kitchen area. The lower balcony fantastic place to sit and have your breakfast. You have the bubbling stream below and it overlooks a ‘secret garden’ on the far side of the stream.

A striking feature of our house design is the curved concrete staircase which the builder constructed a timber form and then poured concrete into it. The bespoke metal handrail made for the house was based design on staircase handrail at the Prince de Galles hotel in Paris.

The cantilevered balconies and the open-plan design meant that our engineer advised that concrete floors and a concrete roof should be used. The walls were built using an insulated concrete formwork system, which in basic term describe like working with Lego. Essentially, lightweight hollow insulated blocks are fitted together and then filled with reinforced concrete. Using concrete that was cast in situ meant that much of the house’s plumbing could be hidden away. Not only is there underfloor heating upstairs and downstairs, energy has there is also a mechanical heat-recovery ventilation system concealed within the ceilings. The underfloor heating system is powered using a water-source heat pump that takes water from the stream. Oncenergy has been extracted, the water is released back into the stream without any contamination. This makes the process environmentally friendly. The decision to use cantilevers to support the balcony provided the opportunity to have a basement room, which offers additional storage space. This also doubles as a machine room, so when the water pumps are running for the heating or for the hot water, no noise can be heard in the house.

The end result is that, in ‘Streamline house’ a retro modern chic has been combined with state-of-the-art energy efficiency, to create a building that does more than go with the flow.
