Project Overview

DREAM Collaborative provided full architectural design services for the 79,000 sf office fit-out in a mid-rise building for the headquarters for Mimecast, a world-wide provider of cloud-based email security and email risk management for businesses. We collaborated with the project team to provide full design services including test fits, programming and construction administration.

The innovative office space features a large connecting staircase which doubles as stadium seating for employee gatherings in the two-story atrium at the heart of the space. The collaborative office accommodates a variety of meetings, casual team gathering, and client demonstrations. Employees enjoy amenities such as a large cafe, game room, juice bar, kitchen, library, gym and fireplace chat room.

DREAM Collaborative was architect of record and Deb Locke from Ldesign provided interior design services.

Moving Forward in the Age of COVID-19

During these times of extraordinary disruption, DREAM Collaborative remains steadfast in our belief that architecture should work toward the Greater Good. In the wake of the COVID-19 pandemic, lines have been blurred and we’re seeing opportunities all around us to reimagine the way we live, work, and organize our society and our spaces. We are honored to play a part in the transition toward a renewed society that prioritizes well-being, equity, and innovation.

As partners, we’re bringing our curiosity and the diversity of our perspectives to conversations about how design and development will need to evolve in a post-COVID world. We’re convening panel discussions and reaching out to other minority and women-owned businesses to brainstorm solutions to the unique and compounded challenges we face. Most importantly, we’re committed to providing the highest level of service and support to our valued clients and partners in the community, who we know are also being pushed to the limits of their resources and ingenuity in order to thrive in this historic moment.
