400 Riverside Street  ·  Portland, Maine

Space to work.
Room to store.

A coworking office and secure on-site storage on one campus, built for contractors and the trades. Month to month, parking at the door.

Why Presumpscot Works

Everything your business needs to run, in one place.

Portland has coworking and it has storage yards. It does not have a single spot that puts a professional office and secure outdoor storage on the same lot, built around how the trades actually work. We do.

01

Office and storage together

A desk for bids and calls, and a locked container or trailer steps away.

02

Built for the trades

A working community of contractors and makers, not a startup lounge.

03

Flexible terms

Month to month and membership options instead of a rigid multi-year lease.

04

A professional front

A real address, room for client meetings, and internet that works.

05

Right where the work is

On-site parking, easy in and out, in the working part of Portland.

The coworking + storage bundle

Your shop away from the truck.

Upstairs in Building B, the coworking space gives you a professional base. Outside, a locked container or trailer holds your tools and materials. Stop running between a storage unit across town and the cab of your truck.

  • Dedicated desks and private rooms with vaulted ceilings and skylights
  • Kitchenette, two bathrooms, fast internet
  • On-site container and trailer storage, steps from your desk
  • Month-to-month memberships, no long lease
