Castle home 14 × 14 m with four round corner towers

I've drawn the plan in plan.dxf and checked it against the brief in preview.png. The last check fixed three overlaps: the north arrow, a tree that covered the title, and a wardrobe in the way of the Bedroom 2 door. Total area in the room schedule is 234 m². - Keep: 14 × 14 m, with grid A–D at x 0 / 7 / 9 / 14 m and grid 1–3 at y 0 / 9.5 / 14 m. - Rooms: - Great Hall, 82.4 m², with a central fireplace, sofa, two armchairs and a dining table for six. The double entrance doors are in the south wall. - Kitchen, 44.4 m², with a counter along the east wall (stove, sink, fridge) and a round table. - Bedroom 1 and Bedroom 2, 28.4 m² each, with a double bed, nightstands and a wardrobe. Both open off the hall. - Towers: four round towers of 4 m diameter, 12.6 m² each. Each has its own door from the keep and one window. - South-west: spiral stair. - South-east: pantry, next to the kitchen. - North-east: bathroom, entered from Bedroom 2. - North-west: reading nook, entered from Bedroom 1. - Also on the sheet: windows, garden trees, dimension chains (overall and per grid bay), floor level marker, north arrow, title, room schedule and legend. - Layers: A-WALL, A-WALL-PATT, A-DOOR, A-GLAZ, A-FURN, A-FLOR-FIXT, A-FLOR-STRS, A-PLNT, A-GRID, A-ANNO-DIMS, A-ANNO-TEXT, A-ANNO-SYMB. Assumptions I took: - Keep walls are 0.40 m and tower walls 0.30 m for a castle feel, instead of the usual 0.15 m. - Each tower is centred on a corner of the keep. The quarter of the tower that falls inside the keep has its own curved wall, so each tower is a separate room. - The round walls are drawn as 12-sided polygons, and the spiral stair is shown as a straight 10-step flight inside its tower. - Areas are approximate: each keep room that has a tower in its corner loses about 3.1 m². - Plot scale is 1:100.
