Built environment.
Cultivated landscape.
Sirak is a design studio dedicated to exploring the relationship between the built environment and the cultivated landscape. Hand-cast concrete, made to order.
The Studio
A bridge between two worlds.
Our collection of planters serves as a bridge between the built environment and the cultivated landscape — designed as tools to bring plants into sophisticated spaces. Drawing inspiration from the ancient Mediterranean, our pieces reflect the artistic traditions of past civilisations while maintaining a strong foundation in contemporary design.
At the heart of our work lies the belief that gardens are profound expressions of a life richly lived. Plants hold the transformative power to elevate a space, and our mission is to provide architects and designers with vessels that allow greenery to become an intentional and integral part of their projects.
"
Gardens are living expressions of time and place — reflections of our ideals and aspirations, landscapes shaped by history and culture, and imbued with elements of fantasy.
Adam Sirak, Founder
The Founder
Adam Sirak
Raised in Miami surrounded by nature, Adam's upbringing instilled in him a deep connection to the natural world. With landscape designer parents and a childhood immersed in South Florida's flora, Adam developed an enduring passion for gardens as works of art and transformation.
We also specialise in designing outdoor environments that naturally integrate with architecture, emphasising the dialogue between built form and nature. Every project begins with the conviction that a garden is not an afterthought — it is an argument for how a space should be lived in.
Philosophy
Ancient Mediterranean
Our forms draw on the artistic traditions of past civilisations — objects that have earned permanence through proportion and purpose. Every vessel in the collection begins with a resolved decision about form.
Contemporary Design
Inspiration from antiquity is held in tension with a rigorous contemporary design practice. Nothing is decorative for its own sake. Each piece must justify itself through its relationship to the space it occupies.
Made to Order, Cast by Hand
Every planter is cast by hand in fiber-reinforced concrete in our studio. Twelve hand-applied surface finishes. Eight to twelve weeks from order to delivery. Nothing in the process is shortened.
The Process
Cast by hand.
Six stages. Twelve weeks.
Each planter is made by hand in our studio. From the first drawing to the final surface, nothing in the process is shortened.
A resolved idea.
Each form in the collection begins with a decision about proportion. The design process continues until nothing can be added or removed. Only then is a mould made.
Built to cast.
Moulds are fabricated by hand from the master drawings. Each form is checked against the design specifications before any concrete is prepared. The mould determines everything that follows.
Material by design.
Sirak concrete is fibre-reinforced — a proprietary blend developed to achieve structural integrity at the wall thicknesses the designs require. Each batch is mixed to tolerance. The composition does not change between pieces.
Poured by hand.
Concrete is introduced into the form in controlled layers. Each layer is worked by hand to remove air pockets and ensure even distribution. The pour takes as long as the piece requires.
Time is the process.
Cast pieces cure for a minimum of seven days before demoulding. Temperature and humidity are controlled throughout. The curing period cannot be shortened without compromising the structural character of the piece.
Character by hand.
Each surface is ground, sealed, and finished by hand. The applied finish — chosen at the time of order from twelve options — determines the final appearance of the piece. No two finished surfaces are identical.
Every piece is made to order.
Eight vessels. Twelve finishes. Eight to twelve weeks from order to delivery.
