Primrose Hill - Joakim OConnor Construction


We have been working with [Joakim O’Connor] since June 2014 on a renovation and extension of a 1960s property in Hackney. Theo never compromises on quality and the team of tradesmen that he’s assembled share this ethos. Communication has been very good — Theo is always available to discuss a worry you might have and Siobhan is very organised. They are a friendly and trust worthy company and we are really happy with the build.

— Sam Spruell

I readily recommend Theo and Siobhan, and will certainly contract with them again. The work was accomplished in a professional and thorough manner and on schedule, with a minimum of problems. I have received many compliments on the building.

— Marios

I felt I needed to write and state how pleased I am to have found a building company that I can respect. Theo has given me so much confidence, from first site visits through to ongoing maintenance. I find that communication with the company is excellent and no job is too small.
