A Dutch builder, at home in Altea
Our own team of tradespeople who help find the best solution, and a regular network of building partners for every specialism. With one point of contact for the whole project.

Our own people, regular partners
We work with a professional team of our own people, each with their own speciality. They know their trade and help find the best solution.
We also work with a large, regular network of building partners for every specialist job: roofers, electricians, plumbers, carpenters, tilers and plasterers.
One point of contact
As a client, you have one point of contact, so communication is smooth and free of misunderstandings. The site manager keeps a close eye on progress and you are kept informed throughout.
We speak English, Dutch and Spanish, and are happy to show you previous work in person, so you can judge our way of working and the standard of finish for yourself.

What our clients say
From the design, application of planning permission, permits required and consultation with ourselves regarding every step of the project the level exceeded our expectations.
A very professional approach, and they always keep to what has been agreed. The work is closely followed up and afterwards everything is neatly cleaned up.
Daan Groen renovated our villa. Skilled/quick and for a fair price. They keep their word and do excellent work.
I have commissioned building work 17 times, both for business and privately; … my experience with Daan Groen tops the list, thanks to their flexibility and mutual respect.
