SA-CA-003 Design Profile Cube
Black Timber Cube Sauna
A sharp-edged modern cube with black-stained cladding and a large glazed front. Dual-ready heating and a generous glazed wall make it a design-forward profile that still carries a full cold-climate envelope behind the flat roof.

- ClimateCold, Coastal Moisture
Recommended use
Contemporary urban gardens and courtyards where the sauna reads as an architectural object and either electric or wood heat may be chosen.
Best suited for: Design-led urban gardens and courtyards · Owners wanting an architectural statement piece · Groups of three to six sharing longer sessions · Builders or contractors comfortable with membrane roofs and structural glazing

Design characteristics
- Pure cubic massing with a flat, membrane roof and concealed drainage
- Full-height glazed wall and door facing the deck for a strong indoor-outdoor connection
- Facing benches arranged to keep the glazed view clear from the upper tier
- Integrated covered deck platform that extends the cube's footprint for cooling
Construction notes
- Engineered flat roof with tapered insulation and a single-ply membrane over the warm envelope
- Full cavity insulation and taped vapour barrier behind the thermowood interior lining
- Large fixed glazing units set as sealed tempered assemblies with careful vapour detailing at the frames
- Pier or slab base carrying the added glazing and deck loads, with a sealed drained floor
Heating profile
- Drawn to accept either an 8–10 kW electric heater or an equivalent wood stove
- The large glazed wall raises the effective heating volume, pushing the heater toward the upper class
- High stone capacity supports steady steam in the larger, glassier room
- Glazing choice is the biggest single influence on warm-up time in this profile
Final heater selection must follow the heater manufacturer's sizing instructions, safety clearances and local electrical or fire-code requirements.
Advantages
- Distinctive modern form that works as a garden centrepiece
- Dual-ready heating keeps the fuel decision open
- Generous glazing brings daylight and views into the room
- Full insulation supports four-season use despite the flat roof
- Integrated deck provides a natural cooling zone
Limitations
- Advanced build: flat-roof waterproofing and large glazing are unforgiving
- Extensive glazing increases heat loss and heater demand
- Black cladding runs warmer in summer sun and shows dust more readily
- Higher material and labour cost than a simple insulated box
Common planning mistakes
- Treating the flat roof as a low-slope afterthought instead of a detailed assembly
- Over-glazing without accounting for the added heater load and heat loss
- Ignoring vapour detailing where large frames meet the warm envelope
- Placing benches so the upper tier bakes against the glass in direct sun
The Black Timber Cube Sauna is the archive’s study in modern massing: a plain cube where the design interest comes from proportion, a single large glazed wall and a dark rainscreen rather than ornament. It is a good profile for seeing how glazing and roof type trade off against efficiency and build difficulty.

Frequently asked questions
Can the Black Timber Cube Sauna use wood heat?
Yes. It is drawn as a dual-ready profile that can accept either an electric heater in the 8–10 kW class or an equivalent wood stove with the correct clearances.
Does the large glazing hurt efficiency?
Generous glazing raises the effective heating volume and heat loss, which is why the profile leans toward the upper heater class and treats glazing as the key variable.
Is a flat roof suitable for snow country?
A properly built warm flat roof with tapered insulation and a membrane performs well, but it is an advanced assembly and must shed or hold snow loads by design.
What does the black cladding involve?
The reference finish is a charred or black-stained thermowood rainscreen; it is durable but runs warmer in sun and needs periodic re-coating depending on the product.
How many people does it seat?
Three to six, with the bench layout drawn to keep the glazed view open from the upper tier.
What foundation does it need?
Concrete piers, a slab or ground screws sized for the added glazing and deck loads, over a sealed and drained floor.
