Have your next party at Leonardo’s Basement!

Birthday, bachelorette, bachelor, shower, retirement, and other celebrations are available for children, teens, and adults. Guests design and build creative engineering, technology, or art projects to take home.

Our Approach

During the summer and school year participants at Leonardo’s Basement are encouraged to build their ideas. Birthday parties for young people are no exception. Rather than offering a list of building projects to choose from, each guest will make what we call a “Build What YOU Want” project, crafting a backpack-sized or smaller 3-dimensional design to take home. (Adult parties can be structured differently, with a specific building theme or goal.)

A wealth of building materials and tools are available to ensure that project building is engaging for all ages and skill levels. An instructor is available, if needed, to help guests as they plan and complete their creation.


Parties for ages 6-17 last two hours and are held on Saturday afternoons beginning at either 12:30 or 3:00pm. (adult party times are more flexible.) The first hour and forty minutes are spent building individual projects. During the last 20 minutes the group moves to a different area of the shop to eat treats that you provide (along with utensils and plates.) We provide a plastic tablecloth. Please limit the number of adults to immediate family members. Parents/Guardians of the birthday person are responsible for connecting guests with their rides, before and after the party.

Reservations are first-come, first-served. The workshop is located in the center of the Twin Cities, in the Prospect Park neighborhood of Minneapolis, near Hwy 280 and University Ave, at 2 Malcolm Avenue SE (entrance on SE 4th St.) Minneapolis 55414. On-site parking is extremely limited. Let the parent/guardian of guests know that this will be a drop-off party.

Parties for Adults
Parties for adults include birthdays, special occasions, and corporate events. Most last two hours and projects can be designed for particular themes if you wish. There might be an additional cost if projects require specific materials.
Adult parties can be scheduled any day or evening of the week. You can bring snacks and beverages from which guests can graze during the party.


Parties cost $30 per guest with a $300 minimum. The fee includes an instructor and materials for each student to build a backpack-sized or smaller project home to take home. No deposit is required and you pay on the day of the party with cash, check, or credit card.
