"Our brief called for the extension and refurbishment of a 180 year-old terraced house. Sterrin and Diarmaid of SOSA responded to it in a truly creative way. It wasn’t clear to us how creative - both with the great new spaces they managed to conjure up and with the detailing and finishes – until the work was finished. Their design is full of clever touches and ideas that have revolutionized the way we live in the house (in a good way). Sterrin and Diarmaid’s vision of how to get the best out of the site far exceeded our hopes. They were always happy to accommodate our input as clients – and we were never less than delighted with any decisions that we left to them."

"The extensive refurbishment of our period family home in Rathmines has proved a great success in the main thanks to the design and leadership of the SOSA team of Sterrin O’Shea and Diarmaid Brophy. The project involved the building of a kitchen/dining extension and the total refurbishment of the main house. SOSA’s design involved excellent use of the limited space available. It was both visionary, practical and the proportions of the extension work extremely well. The management of the project could not be faulted. Dedication, efficiency, budget conscious with excellent attention to detail. The input for both design and finishes were inspiring. We were impressed by how SOSA managed to coordinate all aspects of the project whilst always welcoming input from the client. As well as being very professional we found both Sterrin and Diarmaid to be most helpful, approachable and pleasant to deal with at all times. They really went above and beyond. We really felt the whole project was in safe hands throughout."

"Sterrin is the architect on the extension and refurb. of our Victorian terrace. I would have no hesitation in recommending her as an architect and project manager. She has done an amazing job in bringing in our project on budget and on time, and has been a pleasure to work with from the start. She has a very strong design ethic but has also been very strong on detail and on executing our brief. She went out of her way to source and negotiate with suppliers on our behalf at several stages throughout our project and has delivered huge value add in this respect, while never once comprising on finish."

G McKabe, Rathmines

"Sterrin designed and project managed our home renovation in 2009 which was completed on time and within budget. Sterrin is an innovative designer with a strong focus on finish. She is a true professional-highly organized, totally committed and completely reliable. She was simply great to work with and because she was at the helm, we found the whole experience a very positive one. We recommend her without reservation."

S + D Browne, Rathgar

"Working with Sterrin proved to be both practical and stimulating. While she has a clearly defined aesthetic she is open to working with the client on finding workable solutions to given problems – problems that emerge in any typical building design project. My day-to-day work is based away from Dublin and it was wonderful to be able to allow Sterrin to project manage all aspects of the operation. Site meetings were positive and creative and she always responded favourably to any of my own ‘creative’ impulses.

"That said her advice on a range of practical matters was always sensible and taken on board by myself as client.

"She has an attention to detail and is both professional and personable in her dealing with clients and builders and  sub-contracted providers  such as cabinet makers,  flooring companies and the range of tasks that one would anticipate."

Dr Hugh Maguire, Glasneivin


"From the initial brief right through the project Sterrin accurately evaluated our aspirations for our home and fed back design ideas to us always in excess of expectations. Attention to detail on every design aspect was relentless and we continued to be enthralled right throughout the project as it evolved. Sterrin was always happy to also consider to our own suggestions and implement them without ever compromising on the overall design. She was calm, patient and good natured with everyone while managing the project through every detail. She was at all times budget conscious and maintained a pace to ensure speedy execution of the project. Her level of professionalism and ethic of delivering a high quality service is apparent at all times. Adopting a holistic approach she also took a keen interest in the interior furniture and design and brought invaluable ideas to that aspect of our home too. Now back living in our new home we love our new living space and we are hugely grateful to Sterrin and her immense talent for her very large part in facilitating us in achieving it.

"I employed Sterrin with the remit to design a house which was contemporary, light and spacious. Also it had to be practical, for every day family living. The outcome is all of the above and more, the result has superseded our expectations. This is down to the architectural ability, drive and project management Skills shown by Sterrin. The project was completed on time and within the Budget parameters set at the start of the project. I found her to be very diligent, conscientious and easy to work with. I would give her the highest recommendation.
