How it all began

Hi there, I'm Michelle, the founder and co-owner of Carnot Construction.

Business management and strategy is where I began my career. I spent most

of my working life delivering multi-million pound projects with some of the largest

corporations in the UK and Australia.


My change in career was born out of a passion for home building and design and a vision to disrupt the building

industry. I grew up in Australia surrounded by a family of building professionals, this really stuck with me and developed my interest in the building industry.

In March 2021 Carnot took a leap forward to steadily grow and expand the business and invited our exceptional site manager and founder employee to join the business in a Director capacity, welcome on board Oleg!  


It has always been and always will be our ambition at Carnot to encourage our clients to actually enjoy and feel excited about building or renovating, see their investment grow and importantly receive a product and service that exceeds their expectations.

Kane - Chigwell

"I'm a self-confessed fussy customer. And just having renovated my whole place - halfway furnished - I decided to touch the only room I said I wouldn't: the upstairs en suite! And with clearly not enough room to fit a cutting machine inside, I knew that tiles would likely need to be cut in the garden and walked through the house. The thought of the mess and the stress all over again was killing me. My original builders were becoming unreliable and I badly needed someone to come in and take the reins. That was Michelle. 

After contracting Carnot Construction, in hindsight, I could have booked a holiday for the duration of the works and still had peace of mind. Michelle made nothing seem like an issue and that gave me comfort and confidence from the beginning. Oleg, the on sight constant, is such a great builder. An all-rounder, efficient, friendly, punctual, tidy, trustworthy and extremely professional. He was great with adapting to my last minute decisions and did what it took to get the job done. A wall-to-wall, bathtub-to-ceiling one piece mirror? Done. After realising that the tiles I ordered were, in fact, small pieces of natural stone, Michelle quickly replaced our intended  tiler for a stone specialist. He is hands down the best I've ever witnessed. 


All of the guys did a great job and I’m so pleased with my new bathroom. The only problem was that I didn’t meet them earlier!"

Rhona & Nicholas - Muswell Hill

“Carnot have completed a large(for us) project on our house, taking over 8 months. We have been very happy with their work. Michelle, Oleg, and team delivered on their schedule of work, and were good communicators throughout. With the help of our valued architect, the budget and timetable was controlled and followed – of course we added a number of extras which they were happy to do. Some challenging problems were solved by Oleg and others, and the ideas, suggestions, and recommendations of Michelle and Oleg were greatly appreciated. We also liked the team, who take a pride in their work. Carnot were punctual, tidy, and efficient – we would highly recommend them”. Rhona and Nicholas

"Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt."

"We are pleased to recommend Carnot Construction without reservation. We have found Michelle to be highly professional, polite, well-organised, punctual, realistic and generally a pleasure to do business with. She made things easy and to run smoothly.


Michelle came highly recommended by an architect we had worked with previously, and fully lived up to our expectations.


Building work is always stressful, especially if you are living in the property that is being renovated. However, we found that all the workers who were organised by Michelle were of an equally high standard, honest, courteous, and reliable. Oleg, who oversaw the practical aspects of the contract is a really lovely person, decent and highly competent. I would happily work with the team again. At the end of each day the house was left clean and the workers were unobtrusive and discreet. They were loved by our cats and our children. They were diligent and focused.
