Design characteristics
- Compact square cube with a low flat roof that reads as a tidy modern box against a courtyard wall
- Dark-stained thermowood cladding for a calm, recessive face that sits quietly among neighbouring structures
- L-bench layout seating two comfortably or three at a closer spacing in a small volume
- Single glazed panel beside the door for daylight without opening sightlines onto adjoining properties
Construction notes
- Framed on ground screws or concrete piers to minimise excavation and disturbance on a confined city plot
- Warm flat roof with tapered insulation, a sealed membrane and a concealed internal drain for a clean edge
- Full mineral-wool cavity insulation with a continuous, taped vapour barrier throughout the envelope
- Thermowood rainscreen over a ventilated batten cavity above a sealed, drained interior floor
Heating profile
- A 5–7 kW electric heater suits the small insulated cube and its moderate glazing
- Moderate stone capacity balances a quick warm-up with a softer, longer-lasting löyly
- Electric heating removes chimney clearances, smoke and fuel storage in a tight courtyard setting
- A timer or remote controller allows pre-heating before an evening session
Final heater selection must follow the heater manufacturer's sizing instructions, safety clearances and local electrical or fire-code requirements.
Advantages
- Discreet, smokeless form that is easy to justify to close neighbours in a dense setting
- Small square footprint fits realistically within tight urban setbacks and screened corners
- Dark-stained thermowood is dimensionally stable and undemanding to maintain outdoors
- Flat-roof cube reads as considered modern garden architecture rather than an outbuilding
- Electric heating keeps operation simple where wood storage and venting are impractical
Limitations
- Capacity is limited to two, or three at a close spacing
- A dedicated electrical circuit is required, which may involve an electrician and a permit
- Flat roofs demand careful membrane and drainage detailing to stay reliable long term
- Moderate glazing offers daylight rather than an open outward view
Common planning mistakes
- Overlooking local setback and boundary rules before fixing the cube's position
- Placing the glazed panel where it looks directly into a neighbour's windows
- Under-detailing the small flat roof and its concealed drainage path
- Undersizing the dedicated circuit relative to the chosen heater class
The Urban Courtyard Cube Sauna is the archive’s study in fitting a modern cube into a genuinely small, overlooked city plot. It shows how a dark-stained thermowood skin, a disciplined flat roof and smokeless electric heating combine into a form that is easy to site within tight setbacks and to justify to close neighbours. Final structural, electrical and safety details, along with setback and boundary compliance, must be confirmed by qualified professionals and the local authority.

Frequently asked questions
How many people does the Urban Courtyard Cube Sauna profile seat?
It is planned for two adults comfortably, or three at a closer spacing on the L-bench.
Is it a good fit for a small city courtyard?
Yes. The compact square footprint, flat roof and smokeless electric heating are drawn to suit tight, overlooked urban plots.
What heater class does this profile suggest?
An approximate 5–7 kW electric heater suits the small insulated cube. Final sizing must follow the heater manufacturer's instructions and local electrical code.
Why electric rather than a wood stove?
Electric heating avoids smoke, a chimney and fuel storage, which is usually easier to accommodate close to neighbours in a dense setting.
How is privacy handled in a tight setting?
The single glazed panel is positioned for daylight rather than an open view, and screening or fencing can be planned to manage overlooking.
Does the flat roof need special care?
A flat roof relies on careful membrane and drainage detailing; these structural details should be confirmed by qualified professionals.
This catalogue profile is intended for preliminary planning and comparison. Final dimensions, structural design, heater selection, electrical work and safety clearances must be confirmed by qualified professionals and the relevant manufacturer documentation.
