Why Mill 1?
- We’ll just say it: Mill 1 is gorgeous. When we created Mill 1, we didn’t mess with perfection: we sandblasted brick, exposed original high-ceiling pine beams and refinished gleaming maple floors. We added a stunning custom bar and modern amenities, creating a serene, beautiful natural backdrop that can be customized to reflect your personality and style. Our space will wow you and your guests.
- Your wedding photos and videos will look fantastic, no matter the weather, no matter the time of day, no matter the season. We’re across the street from a state park and the historic Holyoke Canal Walk, both of which feature incredible natural and industrial backdrops. And our wide variety of indoor, well-lit spaces ensure dry, comfortable guests while offering stunning photos you will cherish for decades.
- Our Event Managers are master stress relievers. They are deeply grounded in managing details, but they lead from the heart, which is exactly what you want for the biggest party you’ve ever planned. We put all our love into helping you plan your special event and coordinating your details with care.
- We take food very seriously. Because personal and tailored food choices make events special and memorable, Mill 1 doesn’t limit you to one in-house caterer. Choose among our variety of five preferred caterers, who consistently provide exceptional service and delicious fare.
- We’re green. We produce electricity onsite using a renewable resource (water) making every event at Mill 1 Zero Net Energy. We’re the greenest site for your celebration!

Frequently Asked Questions
Ceremony
Absolutely, however ceremonies in Mill 1 are only for 50 guests or fewer (see our Water Wheel Wedding package). During these smaller events, we divide the Mill 1 space into a Ceremony space and a Reception space; the Ceremony space will stay set for the duration of the event. All other ceremonies happen in our Mill 4 ceremony space which includes white garden chairs for up to 150 guests and other special elements depending on the package of your choice (see our Ceremony packages). Mill 4 is adjacent to Mill 1.
Decor, Vendor & Mill 1 Staff
Prior to your event, Mill 1 Event Managers will guide you (or work with your Planner) in making sure you have vendors booked and details ready for your special day. They work with you to create a detailed floor plan, arrange for your beverage needs, ensure your vendors have directions and know where to park, etc. On the day of your event, Mill 1 staff sets up tables and chairs, and the Event Manager puts out directional signage, welcomes your vendors, addresses any needs related to the space, and coordinates the flow of the event from start to finish when a planner/coordinator is not available. Mill 1 Event Managers do not decorate or help with the design process, so we always recommend a planner or day-of coordinator if you have the budget for one!
We used to be able to do that, but we’re too busy now! We have events booked sequential days and are not able to manage event material the day before or after. Your rental is for a particular length of time on a particular day. You may pay for access to the space for additional sequential hours on the day of your event for $100/hour. Mill 1 is not responsible for any items left in the space the day before or the day after your event, and you may be charged a storage fee or a waste removal/cleaning fee.
You will be onsite getting ready and lounging in our bridal suites. Your photographer will arrive to take photos while you get ready and you will also do your first-looks (as desired). In the meantime, your caterer will arrive and bring in food to prep, put out linens, and set the tables. Your florist (if applicable) will place centerpieces and other floral details. Your planner or helper will put out your personalized décor items, setup place cards, setup the gift table, and make sure everything looks just how you planned. The bar staff will begin setting up the bar and serving the bridal parties (this must be set up and paid for in advance). Your DJ will arrive to setup their equipment in the Mill 1 event space as well as the Mill 4 ceremony space (where applicable) and do sound checks. And any other vendors you have hired will arrive and setup at this time, which will all be facilitated by the Mill 1 event manager.
Additional consecutive hours to decorate are available for $100 per hour with a $100 minimum. You must ask for any additional time in writing 60 days or more before your event so Mill 1 has time to send an invoice and schedule staff.
Couples/Hosts usually choose one of the following three options:
- Ask someone you know to place and remove special décor items within the set-up time frame.
- Hire a planner to place and remove special décor items and/or to coordinate your event for the day – we cannot express how highly we recommend a good wedding planner/coordinator; they will be one of the most valuable things you include in your wedding budget. Check our Preferred Vendor list for some wonderful event planners.
- Negotiate with your florist or caterer to place and remove special décor the day of your event.
Our packages include black padded banquet chairs, white garden chairs, or antique cross-back chairs with a Mill 1 event rental (depending on your package of choice). White garden chairs are included with a Mill 4 Ceremony space rental. If you would like something different, like the popular Chiavari Ballroom chairs, we are happy to acquire those and invoice them with your Mill 1 rental. Ask your Event Manager about pricing for special chairs if you’re interested.
We used to allow this but there was damage to our floors. We take our floors pretty seriously, so you’ll work with your Mill 1 Event Manager to choose your style of chair if different than what is included in our packages. This also applies to any furniture that you hope to bring into the space; we will rent them for you directly through Mill 1 (we need to consider things like fire-ratings, scratch free feet, weight limits, etc.)
We think you’re better off hiring folks with expertise in that, so we don’t rent audio or visual equipment but have excellent preferred vendors who can help you.
This is another insurance issue, so we thank you for your compliance! You may have 3 candles per table and 1 candle per window sill. ALL candles must be in a container and the top of the flame must be at least 2 inches below the top of the container. You may also choose to use LED candles, in which case we have no restrictions.
We’re happy to hang items for you but our insurance carrier requires that Mill 1 staff perform ALL work that is above standing height and/or requires a ladder/lift. The fee for this work is $100/hour with a one-hour minimum each for setup and takedown. You must ask for ladder time 60 days or more before your event, in writing, so Mill 1 has time to invoice you and schedule staff. If you would like to hang something up that does not required a ladder/lift on a painted wall, column, or window please speak with Mill 1 directly during the planning phase; Mill 1 must approve any special décor, including hanging ones, that are attached to the building. You may NOT fasten or nail anything into any of the walls; however we already have hooks preinstalled in the brick that you may use between windows.
Our insurance company requires that all vendors providing services for a fee must be fully insured including liability and workman’s comp insurance.
Yes, BUT they must have insurance if you are paying them. All vendors providing services for a fee must be fully insured including liability and workman’s comp insurance. Insurance designed for DJs and Musicians is very affordable. It covers their equipment and can be found with a simple on-line search.

Bar FAQs
Due to liquor license regulations absolutely no outside beverages (alcoholic or non-alcoholic) may be brought into Mill 1. FYI: there is a $1,000 Friday, Saturday and Holiday event bar minimum and a $500 bar minimum all other days, even if you’re not serving alcohol at your event.
Bringing outside alcohol into our venue is a violation of our liquor license, so no. Any outside alcohol will be confiscated and removed, and you will risk a shutdown of your event.
Yes, but these must be ordered through Mill 1 as part of your bar package, you cannot bring these in yourself as that would be against ABCC rules and jeopardize our liquor license – even if these are meant to be “centerpieces” or “prizes” we cannot allow the potential consumption of outside alcohol in Mill 1. Speak to your Event Manager for details.
Open bar package include all adult guests with the exception of moms-to-be. We have a separate open bar rate for under-aged guests and expecting mothers. Guest counts must be confirmed and paid for no later than 14 days before your event.
No. We do not offer corking fees and we do not purchase alcohol from sources other than our regular distributors. These are ABCC rules we’re following. There are many local breweries that we can order through our distributors, so please check with us as we may be able to add a custom order to your Open Bar package (we cannot do this for a cash bar).
Unfortunately no. The ABCC does not categorize us as a restaurant, and as such, they do not allow us to provide sealable wine bags like those you find in restaurants.
We do not serve shots.
Sure! If you purchase a full Open Bar, you may limit what’s offered to your guests in any way you like, but Open Bar prices per person remain the same. You may also choose to cover only beer and wine on a pre-paid consumption tab for your guests and everything else can be included as a cash bar.
If you purchase a Premium or Ultra Premium Open Bar package you may special order wine or beer. There is a per bottle charge in addition to the cost of the Open Bar package and there is a $250 minimum for special wine/beer orders.
We carry a seasonal rotating stock of two to three craft beers at all times.
