Irregular Lines Maritime brings over two decades of design excellence to the cruise and marine sector, where creative vision meets the precision demands of life at sea.

Our Story

Design Excellence
Across Borders

Irregular Lines was founded by Theodora Martinou, a Greek designer who built her practice in Singapore, driven by a passion for materials, texture, and spaces that feel authentically alive. Over two decades, the studio grew across commercial, residential, F&B, and hospitality design.

The Maritime division was born from a natural evolution, applying the studio's signature precision and creative boldness to one of the most technically demanding design environments in the world: the cruise ship.

Today, operating from Singapore and Greece, we specialise in cruise ship and offshore refurbishment, blending creativity, technical rigour, and sustainable craftsmanship to transform vessels into remarkable spaces.

Theodora Martinou

Founder & Lead Designer

Born in Greece and based in Singapore for over a decade, Theodora brings a rare combination of Mediterranean design sensibility and Asian Pacific market expertise to every project. Her approach blends earthy authenticity with fearless creative expression, designing spaces that feel both timeless and alive.

With deep expertise in cruise ship refurbishment and IMO-certified material specification, Theodora leads the studio's maritime division with precision and passion.

Our Philosophy

Earthy Authenticity.
Bold Creative Expression.

Irregular Lines stands at the intersection of raw materials and fearless maximalist design. We celebrate a Bohemian spirit grounded in natural, sustainable textures, pushing the boundaries of what a marine interior can be.

No two vessels are the same. We design with that truth at heart, delivering interiors that belong to their ship, their operator, and their guests.
