Victor (Vica) laid some engineered oak wood flooring for us in a house that we bought at the end of 2013. The house needed lots of work doing and the new flooring was just one of the many jobs undertaken by Victor and carried out to a very high standard for us. He always paid attention to detail, ensured that the flooring was level and that the new skirting board fitted flush to the floorboards. He was also always able to provide a solution to any problems encountered during the renovation works. I would have no hesitation in recommending Victor as he takes the same pride in his work for others as if he was carrying out work in his own home.

Architecture- 5 May 2018
Contracted to provide options for a new garage office and storage solution. They turned up promptly and were very polite and professional. Through many discussions they ultimately offered up a very good bespoke solution for our situation and once planning is approved we will have no issue with looking to them to complete the actual build. We have had a lot of issues in the past finding reliable trades but with ArhiTERRA design and build we felt confident in their ability to both visualise and implement the build as well as follow through on their promises. I would say that for anyone considering discussing a project with them that it is worth your time to at least have a meeting with them and judge for yourself.

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.

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.

Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.
