Bunkie Plans: Small Sleeping Cabin 8x10, 10x10 and 10x12 with Big Window and Queen Bed Layout

Plans for a small free-standing sleeping cabin (a bunkie) with no loft, in three sizes: 8x10, 10x10 and 10x12 ft. A single-slope roof, a door and a big window on the tall front wall, and room for a queen bed with its footprint drawn on the floor plan. Easy to follow and thorough, with lettered parts, numbered steps with one drawing each, cut and shopping lists, a sleeping safety sheet, a permit drawing set and CAD files. A first build with a helper takes about three weekends.

Easy to follow, nothing left out

Every cut has a letter (A, B, C), and every step shows which lettered parts and which screws go together, so you build it like flat-pack furniture, one step at a time.

You also get dimensioned drawings, a materials and shopping list, a cost spreadsheet and CAD files, so the plans answer the questions that come up while you build.

Permit drawing set included

A permit drawing set is included, ready to adapt for your permit application; some building departments require stamped drawings. It has a site plan template, foundation and floor plan, framing plan, elevations, section, typical details, a code reference table, a load and span basis sheet and a materials schedule for each size. The floor frames are 80, 100 and 120 sq ft; the size under which a small building needs no permit varies by town (commonly 100, 108, 120 or 200 sq ft), and a sleeping use can change the rule, so confirm it with your building office. These are generic DIY plans with no engineer's or architect's stamp.

CAD files included

A SketchUp-ready 3D model (.dae, every board a named part) plus DXF drawings for AutoCAD, LibreCAD or FreeCAD, so you can change a size, add your lot lines or hand the drawings to a drafter.

What you build

Plans for a small free-standing sleeping cabin (bunkie) in 8x10, 10x10 and 10x12 ft.

A skid foundation (pressure-treated skids on a gravel pad or solid blocks), a 3/4 in plywood floor on 2x6 joists, 2x4 walls 16 in on center with a 7 ft 6 in front wall and a lower back wall, 2x8 rafters at 16 in under a 2:12 single slope, T1-11 siding, a built half-lite door with a tempered glass lite (or a store prehung door) and a window you choose, with a shingle or metal roof. It is anchored with ground anchors and is not attached to a house.

• A door and a big window (about 4 ft 9 in or 6 ft 9 in wide) on the tall front wall
• A queen bed footprint with at least 2 ft of clear floor in front of it on every size
• A sleeping safety sheet: escape window, smoke and carbon monoxide alarms, heating and electrical (not designed here)
• Wall insulation and an interior finish as options with quantities; floor and roof are not insulated in the plans
• Skids on gravel or deck blocks, ground anchors set early
• About 36 to 52 hours with a helper, over three weekends (an estimate)

A sleeping cabin has extra rules

These plans design the shell, floor, door, window and roof. They do not design electrical, plumbing, a heater or a stove, and they do not promise that your office will treat the bunkie as a sleeping room or accept the window as an escape window. Ask your building and fire office first.

What you get

• The plan PDF: dimensioned drawings, lettered parts and numbered steps with one drawing each, cut and shopping lists for all three sizes, the inside plan with the queen bed and a sleeping safety sheet
• The permit drawing set at the front of the PDF, ready to adapt for your permit application (some building departments require stamped drawings)
• CAD files: SketchUp-ready 3D model (.dae) and DXF drawings
• An editable materials cost spreadsheet (.xlsx) that works in Excel, Google Sheets and Apple Numbers, with a step-by-step guide to opening it in Google Sheets
• The worksheets again as printable web pages (ZIP), so you can reprint single pages any time
