Here's my proposal for the construction on Eilean Chon.
[i]A square two story wooden cottage 11 paces per side, the walls of the cottage are ringed every three feet with long rectangular trenches filled with soil. These boxes have been filled with climbing roses, honeysuckle, and sweet peas.
The four main chambers all have a balcony, three paces wide and one pace deep, that overlooks the loch. (One of the labs can only be accessed by its balcony.)
The first floor has a large set of double doors, with 2' long shelves framing them to guide the climbing plants around the building's entrances. The double doors open into a cozy antechamber with four comfy cushioned chairs, a table, and a small fireplace. The antechamber leads into two laboratories; a small spiral staircase on the right leads into one of the upstairs laboratories, and all the way up onto the roof.
Each lab has a fireplace, and all five fireplaces in the building share a single common chimney.
The roof of the building is flat, with a 3' tall ring about it, and very narrow crennellations all around. (The roof is filled with soil, and the crennellations allow excess moisture to run off.) The rooftop garden has a narrow winding path through it, and has been planted with willow, gorse, wild cherry, and honeysuckle. The building's chimney extends high above the tree line, and it is covered in a network of thin metal trellis, around which grows sweet red grapes. Though grapes prefer a warmer climate than Scotland offers, the heat the chimney radiates makes the grapes grow healthy and sweet. There are not enough grapes for any kind of wine production, but plenty enough for impromptu snacking.
While the building itself is beautiful, the nature of its exterior is such that there is very poor natural lighting within; all the labs must be magically lit.[/i]
