Two felicitous accidents of siting distinguish this house from the many thousands of similar speculative estate-type houses built in the 1960s and 70s in South Dublin: a triangular corner site and an almost due-South orientation to the rear.
Largely untouched since its original construction, the house required complete replacement of all services, thermal performance upgrading, and the creation of a large family space for cooking, eating, and relaxing.
The rear of the house was opened up completely and a new extension created. This extension is orientated according to the geometry of the site and its outlook is both wider and more private as a consequence.
To the rear, the new rear elevation steps up in height, in proportion to the size of room it serves, and is protected from midday sunshine by a shallow portico which tracks the motion of the sun from morning till evening.
This portico is a timber-framed construction nestled between masonry piers which are finished in white brick. Intended to feel light and more in the character of an interior space, the masonry element to the rear is in distinct contrast to the weighty and somewhat dour character of the original house.
Ground Floor plan
The geometry of the ground floor plan is reorientated according to the long dimension of the rear garden. The new portico is offset from the boundary to leave space for a narrow eastlerly window.
Solar orientation diagram
The portico is shifted off due-South to create a bias towards afternoon, evening sunshine, and avoid any risk of midday overheating due to a large expanse of glass.

The portico consists of a painted timber-framed structure nestled between white brickwork piers.
A narrow easterly window sits in an inglenook area with a lower ceiling. This is free floorspace intended as a play area for children. The bulkhead ceiling above is curved to absorb the shifting geometry of the extension layout.

The kitchen includes a narrow west-facing slot window which admits the last of the evening sunshine.
White brick to the back of the island brings continuity with the new architecture of the building.

Before
The back wall of the house was completely broken out at ground floor area in order to create a seamless transition between old and new spaces.
