The House of Mouse is cooking up something new — but the details are being kept tightly under wraps.

Disney has filed two confidential construction permits for work near the Golden Vine House at Disney California Adventure, sparking speculation about what could be coming to the increasingly busy corner of the Anaheim theme park.

The permits, filed Tuesday with the City of Anaheim, list “new commercial construction” and a “retaining wall,” according to ThemePark IQ.

“Disney today filed two additional confidential permits at this new address for a Fence/Retaining Wall and New Commercial Construction,” the platform reported.

The latest filings follow another permit submitted in July for a retaining wall along the Disney California Adventure parade route.

That project called for a wall measuring 16 feet, 6 inches tall and 130 feet long, with electrical work also included, according to ThemePark IQ.

The construction is listed near the Golden Vine House, formerly known as Blue Sky Cellar, at 777 W. Katella Avenue, #421. The new permits list the construction address as #422.

A map shared on social media identified two possible locations for the mystery project.

One is an area currently filled with rows of grapevines directly across from Avengers Campus. The other is a stretch of land between the Grizzly Peak waterfall and Golden Vine House.

Disney fans may have to wait a while for answers.

Another theme park news outlet, MiceChat, described the filings as a “mystery project,” noting that details about the proposed work remain largely hidden.

“Beyond the wall itself, the details are being held back, and two of the filings for this space carry no public description at all. A true mystery,” MiceChat wrote.

The platform noted the work being done could support additional “lighting, expanded seating, or a festival booth with power.”

“Directly across the corridor, the new Bountiful Valley Brews spot has taken over the flex space that used to hold festival booths, Halloween candy trails, and VIP tour groups,” MiceChat wrote.

“That space is gone from the festival rotation now. And with the new brewery about to open, there’s far too little seating in the area for all those guests, plus all the festival guests during special events like Food & Wine and Festival of Holidays.”

Bountiful Brews, an outdoor bar in DCA, is set to open Nov. 19, WDW News Today reported.

Disneyland officials told The California Post the theme park is “working on enhancements to the area adjacent to the Golden Vine House” and information about the project would be shared at a later time.

The reported upcoming work comes amid other construction at the “Happiest Place on Earth.”

Earlier this year, the ticket booths on the eastern side of the entrance between Disneyland and Disney California Adventure were bulldozed.

The changes are part of DisneylandForward, a major expansion initiative announced in 2024 that promises to transform how visitors enter and navigate the resort.
