About us

Buying the apartment where you will spend your best years is not a decision to take lightly. That is why who builds it matters.

We are Inseryal, part of Marina d’Or Construcciones: the group that built the entire city of Marina d’Or, with its hotels, its leisure parks and its spa resort. Since 1983 we have handed over more than 25,000 homes and walked alongside more than 51,000 families right up to the day they receive their keys. That experience, the know-how of those who build on a grand scale, is what you later feel inside your own apartment.

Much of what you see along this coast today is our work

Behind every development there is our own construction, our own team and a direct, personal relationship that has not changed in forty years: from the first phone call until the moment you first sit down on your terrace. We build with real life in mind, with modern, solid projects designed to last.

Our completed projects speak for us: the Miramar building and Ciudad Jardín 1 and 2 are already finished and lived in. Today we are building Amanecer, on the beachfront, and Cristal, just 379 metres from the sand, with the same standards as always.

Here the day begins with the sun rising from the sea

We build in Oropesa del Mar and Cabanes, in the heart of the Costa de Azahar, halfway between Valencia and Barcelona. Blue-flag beaches, quiet coves, a seafront promenade where it feels good to lose track of time and more than 300 days of sun a year. This is the setting we have been working in for four decades, and the one we want to become your new home.

People, not case files

Our team does not just hand you a brochure and say goodbye. They listen to you, understand how you picture your life by the sea and stay by your side until you find the apartment that truly fits you. No pressure, no obligation, at any of our offices in Oropesa del Mar, Cabanes and Madrid.
