The five retained façades conceal a unified and coherent workspace for Hines and Puig.

Grainhouse, in Covent Garden, is the conversion of five separate historic buildings into one integrated space. Barr Gazetas have led the transformation of a seed merchant’s warehouse, a brass and iron foundry, and a non-conformist chapel into a new European headquarters for Hines, a global real estate investment firm. 

The project involved the refurbishment, remodelling, and extension of the site and Barr Gazetas approached the work with a deep respect for its context and history. The design retains all four frontages of the original buildings, preserving key features such as stonework, mouldings, and brickwork. The block features Mercers Maidens, the symbol of the Mercers' Company, a medieval livery company

The challenge lay in creating a cohesive space while respecting the individual identities of each building. Barr Gazetas achieved this by adding two-story extensions, each tailored to the specific characteristics of the building it complements. This approach ensures that the buildings retain their distinct external identities while internally merging into a single, unified workspace. 

The Grainhouse project is not just about preservation; it's also about progress. Slate mansard roofs and timber dormer windows evoke the past, while full-height curtain walling and zinc/aluminium cladding speak to the present and future.

One of the most captivating additions is the structural glass windows atop the old chapel building. Extending above the roof line, these windows create a modern landmark that redefines this historic corner of Covent Garden. 

Barr Gazetas has prioritised sustainability throughout the project. By retaining as much of the original structure and materials as possible, they have significantly reduced the project's embodied carbon footprint.

Grainhouse is designed to achieve BREEAM Excellent and WELL Platinum certifications, thanks to features like state-of-the-art heating and cooling systems, low-flow fixtures, and a communal landscaped terrace. 

Hines' new headquarters features a striking spiral staircase, extensive planting, and a calming colour palette. Huddle rooms, breakout spaces, and focus rooms cater to a variety of work styles and needs. 

Grainhouse is not just home to Hines; it also houses the fashion and beauty company Puig, whose portfolio includes renowned brands like Paco Rabanne, Jean Paul Gaultier, Nina Ricci, Christian Louboutin, and Charlotte Tilbury. The ground floor welcomes the popular restaurant operator Caravan, adding a vibrant culinary dimension to this revitalised city block. 

Solus Ceramics is proud to have been a part of the Grainhouse project, supplying high-quality tiles that complement the building's unique blend of history and modernity. Our tiles can be found throughout the building, adding a touch of elegance and sophistication to this exceptional workspace.
