Latest review:
We did a lot of research ahead of our loft build, and spoke to customers of the companies we looked at. We were impressed with Toma and her team from the outset, especially in terms of clarity and communication. We sat down with the project team at the start and walked through the week-by-week plan for our build, then a whatsapp group and weekly meets meant we knew exactly what was happening throughout. Our endless questions were responded to swiftly. Additional optional trade-ups (eg top-hung windows, larger bathroom window etc) were discussed and explained with context, sound advice (and clear pricing where nec) but always still optional. Toma's communication with the teams also seemed strong and continuous, with materials always arriving in time and ahead of when needed, no down-days etc - and importantly, the teams all seemed happy and were just lovely people to have around. I realise with hindsight too that the team's care and workmanship really put them a cut above many others in my area and the project remained on schedule. I wouldn't hesitate to recommend ICS for the whole package and in fact we've also chosen to use them again for a kitchen extension.

Michael was responsible for organising and overseeing my self build project, including the demolition of the old house and site preparation. The new detached house is approximately 5000 square ft over four floors including a basement. Michael's diligence, professionalism and reliability were exceptional. I have also used Michael on other small projects and have been equally impressed. Above all, i have found him very trustworthy. I would happily discuss the projects he has been involved with anyone considering offering Michael a project to carry out.

Extensions- 13 Jan 2019
George was excellent throughout - would highly recommend. Although I did not hire George to complete the whole job (as someone in my family is a bricklayer) he was instrumental in completing the build. A few points to demonstrate: - Fair and transparent quote (which was stuck to); - Flexible throughout delays caused by me (planning, etc.); - Supportive (advice on what he would do if he was running whole job); - Professional (including team). I will use him again.

I am a construction professional with a well-rounded background that spans from domestic refurbishments to super-prime residential projects. I began my career working on smaller projects such as bathroom and kitchen refurbishments, loft conversions, and house extensions, gaining hands-on experience in every stage of the build process. Over time, I progressed into managing and delivering high-end and luxury residential refurbishments, where precision, detail, and client expectations are at the highest level. My blend of architectural training and on-site experience allows me to approach projects with both design sensitivity and practical efficiency. I am skilled in budget management, construction programming with Powerproject, and the use of digital tools including Bluebeam, AutoCAD, and Revit to coordinate and deliver work to the highest standards. Whether working on a bespoke renovation or a large-scale development, I am committed to providing quality workmanship and a seamless client experience.
