Hatch. Watertown's Makerspace.

HATCH is a makerspace. Try thinking of it as a public workshop. We have space, tools, equipment, and materials available for your use.

We want to give everyone in Watertown the opportunity to become a maker. We want neighbors to share skills with each other. We want to see you learning from and teaching to each other. Becoming a maker is not about talent—it’s about collaboration, creative problem solving, and the development of a curious and tenacious spirit. It’s for adults and children and for people of all abilities.

Perhaps you think you don’t have that creative spark. We challenge you to explore HATCH and see what you can learn. You might be surprised by your abilities.



Thank you to local video director and editor Adrian Atwood for producing this video.


Where is HATCH?

HATCH is NOT at the library. We couldn't provide this in our current facility, so we've taken our makerspace off-site. We are located in the Arsenal Project (formerly the Arsenal Mall) at 485 Arsenal St. Enter at the Old Navy entrance. You will find us between Pearl Vision and Game Stop.

We thank the Arsenal Project for generously providing retail space free of charge.

Who is HATCH for?

HATCH is for adults and children. We recommend children be 8 or older to fully take advantage of HATCH. Children 12 and under must be supervised by a parent or guardian.

Should I bring my very young child to HATCH?

HATCH is best for children 8 and older. There are some activities that may engage the very young such as engineering toys and basic craft supplies.

Is HATCH free?

Yes, use of HATCH is free. The WFPL/HATCH reserves the right to charge for materials.

When is HATCH open?

HATCH is staffed by volunteers. We have open hours when we have volunteers available. Check out our calendar to see when you can visit.

We are looking for volunteers to help expand our hours.

How can I use HATCH?

There are a few ways you can use HATCH:

You may come any time we're open and use HATCH for a project you’d like to work on.

You may come when one of our volunteer skill mentors is available to teach skills. Some skills you may learn are coding, soldering, sewing, basic hand crafts, 3D modeling, etc. Our skill mentors have a broad range of skills, check the calendar frequently to find out when they are at HATCH.

You may come to a class. Some classes require registration. Details are on the calendar.

Do you have skills you’d like to share? Consider becoming a skill mentor.

Can I use HATCH if I don't live in Watertown?

Yes. Some activities and equipment require a Watertown Free Public Library card or Minuteman Library Network card. Any Massachusetts resident with proof of address and photo identification is eligible for a card and can register at the library on 123 Main St.

Why is the Watertown Free Public Library running a makerspace?

Good libraries evolve. Along with our traditional services we need to provide for the community as needs change. Now more than ever skill development, content creation, and meaningful enrichment is at the center of library services. Don't worry, the books aren't going anywhere.

How can I donate?

HATCH is funded through grants and donations - none of the regular library budget is used for HATCH operations. If you would like to donate you may do so with a credit card here.

You may also make a check out to the Watertown Free Public Library Building Committee and send it to the library at 123 Main Street.

Because we have a small space, we generally do not accept materials donations. If you have something you think would be particularly useful to HATCH you may contact Natasha at nr-k@watertown-ma.gov.

How can my organization collaborate with HATCH?

Collaboration is integral to the maker movement. We are interested in partnering with local organizations to make sure HATCH is reaching all those who can benefit from our operation. Please contact Natasha at nr-k@watertown-ma.gov with inquiries.
