I found out I needed party wall awards from no less than 8 neighbours and AFTER strip out works. Richard Hourican made saving the day a breeze, meeting all our new neighbours and walking them through the somewhat complicated party wall process. I had been told that one could do party wall awards yourself, I now understand there is absolutely no way that would have been done correctly or as efficiently without the help of Richard and his team. I recommend you call him and explain your situation, he'll sort it and give you a very reasonable fee for the pleasure.

I can’t recommend Richard and Hourican Associates highly enough. From the outset of our loft conversion project, they demonstrated professionalism, deep expertise, and a calm, solution-focused approach that proved invaluable. Not only did Richard provide clear, practical guidance through the technical and regulatory aspects, but he also managed sensitive party wall matters with diplomacy and clarity. His ability to communicate effectively, mediate concerns, and ensure we remained compliant with all building approvals gave us great peace of mind throughout the process. If you're considering any home extension or loft work, especially where neighbour relations or party wall matters might become tricky, I’d strongly recommend working with Hourican Associates. An absolute asset to any project.

Richard came highly recommended and I wouldn't hesitate to recommend him to anyone - especially if, like us, the party wall issues are complex. Richard is terrifically knowledgeable about the practices and law concerning party wall boundaries and very experienced. He is also great to deal with - responsive and highly professional. In our case, he was able to navigate the complexities (and personalities involved) with great skill. We are enormously grateful to him.

I first met Richard in Sept 2016 for a coffee, he went through his services and we gave him a trial run on a fairly complex party wall award requirement for a mid terrace in Fulham SW6. He booked the Schedule of Condition survey the following day and had the awards in my email within the week. Richard is now our main recommended PWS and since then has completed 100s of jobs for our clients. Richard is courteous, strong on customer service, good value, extremely knowledgeable and always a pleasure to deal with.
