Over the last couple of months, the Museum has featured an interview with Diane Disney Miller, talking about the reasons she and her family decided to embark upon the enormous effort of creating a museum that will do Walt’s memory proper service.

This month, as you can see, we’re featuring some photographs of work at the Museum -- largely taken in the ''courtyard'' area where one of the most exciting features of the Museum will be located: a two-story ramp. Explains Walter Miller -- Walt’s grandson, namesake, and a guiding light behind the new Museum, ''This ramp -- it’s Gallery 9 in the Museum -- will include artifacts like the Lilly Belle (the train Walt built for the backyard of his house in Holmby Hills) and the little red car given to my brother Chris that was the model for the Autopia. And visitors will have the chance to see and learn about many things including the television shows like Disneyland and the Walt Disney’s Wonderful World of Color. And there’s going to be a huge model of the Park, Disneyland, in there.

''My Mom has referred to this space as ‘Christmas morning.’ It will be a controlled environment. You’ll be walking along in the previous gallery, come around the corner, and arrive on this two-story exposed ramp where you’ll see the creative explosion in the mid-1950s.''

The Museum is being housed in a building currently known as ''104,'' its street address. In its current form, the building looks not dissimilar from many of the others on the Presidio site -- it’s a great deal like an empty army barracks, which is precisely what it was.

''Our building housed two different barracks,'' explains Walter. ''Two different troops and their own facilities were there, including a tailor and a barber. Both troops would come out of the building onto the main parade ground and do their marching.''

And how will the exterior of the building differ from the way it looks now? Very little, it turns out.

''We’re preserving the historical look of the building. Even the paint will be the same. The back of the building will look different though. The back will be glass and will complement the historical part, but be more contemporary in design. When you look into the new infill area on the side, you’ll be able to look in and see historical fabric.''

''The actual construction was really the soft demolition and that was the toxic removal. Two months ago -- they removed all the asbestos that was in the tiles and all the lead paint... then they started with the subterranean level and the back courtyards...''

''They’re also shoring up the lower floor -- they’ve got to go way down into the earth to accomplish that. And they’ll put a massive footing there to brace the building as they continue to excavate. They’ll remove more dirt and they’ll lower that whole subterranean floor for a learning center and theater. The theater, with 100 seats, will be in space directly under the ramp.''
