She wanted a venue that felt private. Not a forty-five minute
drive to one.

Every beautiful venue in the region is an hour from her mother's house. An hour from the hotel. An hour from anything she forgot. The ones close to the city feel like hotel ballrooms. The ones that feel like a private estate are forty-five minutes down a gravel road her grandmother is not going to drive at eleven at night.

Willow Haven is a different answer. A venue with an eighteen-hundred-square-foot bridal suite, one wedding per day, and hotels twelve minutes away. In the city, and still private. Timeless, clean, modern. Built by a family who watched their daughters get married and knew exactly what the right venue should feel like.

Willow Haven opens November 2026. The couples booking now are the ones it is being built for.

02 The Bridal Suite Where the day begins. Eighteen hundred
square feet.
White and gold.

Thirty-foot ceilings. Room for her, her mother, her sisters, the photographer, the florist, and the two bridesmaids who always run late. A separate entrance so nobody walks past her by accident. Quiet when she wants it quiet. Loud when the champagne comes out.

03 The Groom Suite His half of the morning. Nine hundred
square feet, separate
from the rest.

Games. A television. A fridge. Room for his brothers and his dad and the groomsman who forgot a belt. The suite opens directly onto the courtyard through a large wood door set in a stone wall, so his half of the wedding party can spill outside without passing through the hall.

The Private Showing Walk it before it's built. See the plans.
Meet the family.

Construction is happening on a piece of land the Bonacorsi family already knows by heart. Until the building is standing, private showings happen at their offices on the same parcel. Claire Gonzales or Mia Bonacorsi walks you through the floor plans, the renderings, the pricing, and the timeline. You meet the people who will be there on your wedding day.

No pressure. No sales tactics. A conversation about whether this is the right fit for your day, held by two sisters who have planned a wedding in the last two years themselves.

The Family Behind Willow Haven Built by the
Bonacorsi family.

Bret and Jennifer Bonacorsi watched their daughters get married. Both days were good. Both had a moment where the family walked out of the venue thinking the same thing: this could be done better.

So they decided to do it. Willow Haven is going up on the same parcel as the Bonacorsi family jewelry business, twelve minutes from the hotels, in the city. Claire and Mia, their daughters, run the private showings. Mia is already booked to get married at Willow Haven herself.

When you book here, you are not handed off between a sales manager, a coordinator, a venue rep, and a clean-up crew. You are hosted by a family who is building this to be the venue they wished they had.

Reserve your spot You'd be among the first to ever say yes here. Private showings run throughout the week. You will walk the plans, see the renderings, and leave knowing whether your date is still available.
