Look what my Client's are saying.......

"Niamh, the extension is wonderful.  We had everyone over for Laura's communion  and it was just fantastic to be able to entertain so easily. We make so much more use of the garden now as well. We couldn't be happier" - Philip and Linda O'Connell, Middleton

"At last we come to say a big Thank You for helping us to renovate our kitchen/sitting space. We are absolutely thrilled with it. It's warm, cosy and looks great. 'Completely transformed' is how someone described it the other day." -Mary and Peter Davies Monsktown, Cork

"Niamh, I wish I had met you years ago.  We have so much more space and so much more storage, without adding a single square foot. We cannot believe it is the same house. We are getting great use out of the new open plan kitchen-dining- living room and the master bedroom is divine. We won't do anything without you again!"-Sheila Mc Sweeney, Ballincollig, Cork

"Thank you very much Niamh you were extremely helpful and I am delighted with all the ideas and doubt I will be in touch again!  Thanks again " -Cait Lane, Ballyvourney
