We're very happy with our new garden office which was designed & constructed by Richee Carpentry. The construction was quick & efficient and communication was clear and timely throughout, last minute changes were accommodated on the fly such as us finding a skylight and asking for it to be installed. The trades involved were polite and professional and the living roof is just fabulous!

I cannot fault Dan in any way. His work was exemplary. He was friendly, approachable and guided me through every step of the reconstruction process. He always arrived on time and went over and above what was expected of him. I trusted him and would, without question, give him my full recommendation.
