Kostarelos, Deli

From One Dairy To Twelve Stores.

Our team created a brand new concept for our client Kostarelos, which involved the brand’s first shop-in-shop to promote the company’s top-quality products and authentic Greek flavors. The store is organized into areas, dedicated to different experiences based on the product offering, all in an open layout which invites the customer to explore more.

Kostarelos had been producing exceptional Greek dairy since 1937 — but the business was trapped in a format that couldn’t grow. A family brand with artisanal heritage, a traditional retail format that limited growth, and no replicable model for expansion. Meanwhile, the market for premium Greek gastronomy was accelerating internationally, with competitors like Ergon (26 stores) and Yoleni’s already scaling. Kostarelos was the only vertically integrated producer-deli in the Greek market — farm to barrel to shelf — but this story was entirely invisible in its retail environment. The challenge had become strategic, not operational.

STIRIXIS engaged across Strategy, Design, and Execution to transform the business from the ground up. The strategy identified the core untapped asset — Kostarelos’ vertical integration from farm to barrel to shelf — and built the entire concept around that provenance story. A hybrid format combining deli retail, sit-down dining, and takeaway was designed around three revenue streams from one model. Heritage storytelling was embedded in the physical space through brand environment design from signage to packaging, specification of materials and fixtures, and a scalable, franchise-ready system with consistent identity across all touchpoints. STIRIXIS continues to offer consulting services to the client, keeping the concept updated and refined.

The flagship opened in Kolonaki, Athens in September 2015. Within ten years, Kostarelos grew from a single legacy location to 12 stores across Attica, including premium sites at Athens International Airport and Costa Navarino. The concept generated three revenue streams from one model — retail, dining, and B2B/export channels — and curated a network of 100+ artisan Greek producers across its shelves and menu. Today, Kostarelos is a reference point in Greek delicatessen retail. The project won three international design awards: IPA 5-Star Best Retail Interior Design Greece 2016–2017, IPA Best Retail Interior Europe 2016–2017, and the Build Architecture Award for Best Greek F&B Project 2016.
