Cedrus International® House of Ci — a glass façade at dusk

Cedrus International® House of Ci

The house where visions take form.

One global house of design. Nineteen integrated solutions under one roof. So your project moves from the first sketch to the final key with one team.

Live happening · The Kingdom

Saudi National Day is coming
— the 96th.

On 23 September the Kingdom turns green — and the house that builds for its future celebrates with it.

كل عام والمملكة بخير

Live from the house — the Riyadh Music Festival

Live happening · Riyadh

The Riyadh Music Festival is on.

The city is alive with sound this season. Indeed, the house is there — on stage, behind the scenes and all around it.

From the Journal

A memory to be remembered.

Memory 01 · French-Saudi Business Forum

The Making of a Stage.

Three days, two nations, one stage: how the House of Ci drew, built and lit the French-Saudi Business Forum — from an empty ballroom to a tower that wore both flags, and a bilateral beneath the portraits of the Kingdom.

The House · Cedrus International®

One house for the whole
built environment.

Cedrus International® — the House of Ci — designs, engineers and builds places with one accountable team. Because every discipline lives under one roof, a bold idea keeps its intent from studio to site: architecture, interiors, fit-out and brand speak one language here, and answer to one name.

سيدروس إنترناشونال® — دار سي — تصمّم الأماكن وتهندسها وتبنيها بفريق واحد مسؤول. ولأن جميع التخصصات تعمل تحت سقف واحد، تحافظ الفكرة الجريئة على جوهرها من الاستوديو إلى الموقع؛ فالعمارة والتصميم الداخلي والتشطيب والعلامة التجارية تتحدث هنا لغة واحدة، وتجتمع تحت اسم واحد.

Most projects lose their spark between suppliers. The House carries a vision across every stage instead — so decisions travel cleanly, budgets hold, and the standard never slips from the first sketch to the final key.

تفقد معظم المشاريع وهجها بين المورّدين. أمّا دار سي، فتحمل الرؤية عبر كل مرحلة — فتنتقل القرارات بوضوح، وتصمد الميزانيات، ولا يتراجع المعيار من الرسم الأول إلى المفتاح الأخير.

One brand, end to end — a lantern in the atelier of Cedrus International® House of Ci

ONE BRAND, END TO END

From the shell to the last chair, one team is answerable.

Most projects pass between many hands, and intent leaks at each handover. Instead, House of Ci holds the whole chain — design, engineering, build, furniture and brand. As a result, a House of Ci project reads as one idea. Moreover, the same discipline guards the budget and the program.

تنتقل معظم المشاريع بين أيدٍ كثيرة، وتتبدّد الرؤية عند كل عملية تسليم. أما دار سي، فتدير السلسلة بأكملها — التصميم والهندسة والبناء والأثاث والعلامة التجارية. لذلك يبدو مشروع دار سي فكرة واحدة متكاملة، كما يحمي هذا الانضباط الميزانية والبرنامج الزمني.

Design Philosophy · The Creed of the House

We listen. We see. We create.

Every project in the House of Ci begins the same way — in silence, with a pencil, long before the cranes.

يبدأ كل مشروع في دار سي بالطريقة نفسها — في هدوء، وبقلم رصاص، قبل أن تبدأ الرافعات عملها بوقت طويل.

I

Listen

Every brief hides a second brief. We stay in the room until we hear it — the ambition behind the program, the quiet fear behind the budget, the legacy behind the plot.

II

See

Then a clear eye finds what the site, the light and the people truly need — and, just as fiercely, what they can live without.

III

Create

Only then do we draw. Slowly at first, precisely forever — architecture, interior, object and story composed as one gesture, answerable to one house.

Draw slowly · Build honestly · Finish forever

The AtelierPencil before pixel — where every project begins.

Luxury is not what you add.
It is what you dare to refuse.
