During the Victorian era, there was a strong gothic revival movement. The Victorians were responsible for some very elaborate fairy-tale like castles and buildings. In that spirit, I have created Blackthorn Hall. It has the flexibility to fit into a Victorian setting (especially dark Victorian), Gothic, or as a spooky Halloween venue.
Beyond a recessed entry, is the main floor, in an L shape with a staircase under the central tower. Roof beams mounted on white marble supports lift up a curved wood ceiling into a high gothic arch. The stairs lead up to a second floor room, with a turret alcove with stained glass windows that open to a front corner view. In the rear, stained glass doors open to a small rear balcony.
Further up the stairs is the high tower room. Large arched windows afford a 360 view. Perfect as a private getaway, ritual chamber, or attic storage for all those dusty old trunks.
And somewhere in the house, a small secret nook entered by a secret panel

Blackthorn Hall has a footprint of 23m deep by 20m wide, with a height of 38 meter to the top of the central tower lightning rod. It's 253 prims. Fully modable, and copyable, no transfer. Uses Rezz Foo for easy setup.
Available at my main store in Caledon II (in fact, it IS the new main store) and at my other stores including Caledon Cay. Also available on Slexchange.
