About us

« The feel of an artist, the precision of an economist »

At ECC Chapuis-Duraz we deal with the design, construction and quality control the projects we are commissioned to carry out. ECC: E for economy, C for coordination, C for construction. Three letters that symbolise what we do and the fields in which we work.

ECC is based in Savoie, at the gateway to France’s most prestigious winter sports resorts. Our local roots and familiarity with the area, the skilled men and women we work with and their qualities are all assets that make the difference and forge the hallmark of our identity.

At ECC we are inspired by tradition while keeping abreast of the latest trends and technological and environmental developments. At ECC, we turn your dream into reality.

Our projects

« Our philosophy is to raise your project to new heights, turning it into an original creation and a durable asset. » Messrs Chapuis & Duraz (directors of ECC)

Starting out from the demanding principle that every project must take the form of a unique creation, we leave no stone unturned in achieving this result. Our goal is for each of our projects to be remarkable and here to stay.

We have already completed around a hundred projects, a constellation of chalets in the heart of the most prestigious ski resorts in the French Alps, each one a star that twinkles in the firmament of our reputation. Your satisfaction is the best compliment you can pay us!

« Perfection is a path, not an end. » Korean proverb

ECC is certified by UNTEC (the French National Union of Construction Economists) and OPQTECC (the French qualifying body for construction economists and programme managers).
More than just a certification awarded by a professional body, this is a hallmark of confidence and quality. From project elaboration to completion, from the start of construction to delivery, at ECC we continue to build on our know-how while keeping in mind our constant quest for perfection and excellence.
