Marion Roche Martin - a former software engineer with Apple - recently returned from Silicon Valley California to the house where she grew up in Bishopstown, County Cork.
Determined to swap the high-pressure life of Silicon Valley for a calmer, more family focused existence, Marion and her American husband Engel and their two young daughters have moved in with Marion's mother Kathleen.
Three generations of the Roche family have done well to co-exist in a house with a chaotic layout of tiny rooms where Kathleen has lived alone for the last decade. But this is a special house. Kathleen wouldn't live anywhere else.
With the demands of two school-going kids and both Marion and Engel studying for MBAs. Dermot's challenge is to free up the convoluted internal layout, combine family space with working space, and give Kathleen her own autonomy.
The budget, for a change is healthy, but with three generations of one family to consider, each with their own specific needs, cost will be the least of Dermot's worries.
In short, Dermot has to combine the open spaces and free flowing layout Engel and Marion are used to from their time in California, while providing family space and allowing Kathleen to retain the feel of the house she loves.
As the family decamps to Dublin for the build, Dermot has to convince them to retain a key aspect of his design. The question is: can he convince them?
