A modular road-stop system conceived for long-distance travelers on Iranian highways, combining affordable short-stay lodging, a roadside restaurant, and canopy infrastructure in a single cohesive built environment.
Millions of Iranian families travel long distances by car, often covering overnight routes between cities with few formal rest facilities. This project was conceived as a scalable, affordable, and architecturally coherent rest stop, not a hotel, not a motel, but something purpose-designed for the short-stop traveler who needs a few hours of sleep, a hot meal, and a safe place to leave their vehicle.
The concept was developed internally at Syeh Sazane Mehr Gostar, where the designer, working in close collaboration with civil engineers on the team, developed all spatial dimensions, module configurations, material specifications, and layout logic from the ground up.
"The idea was simple: treat the road traveler with the same dignity as any hotel guest, just without the unnecessary cost. Everything else followed from that."
The target group was identified early: middle-income Iranian families and solo car travelers driving inter-city routes, journeys of 4 to 12 hours that span day and night. These travelers are underserved by existing infrastructure. City hotels are expensive and located off-route. Highway petrol stations offer fuel but no rest. Informal stops are unsafe.
Three core user needs were identified through field observation and stakeholder discussion:
| Need | Design Response |
|---|---|
| Short-term safe sleep (2 to 6 hrs) | Individual lockable rest modules with essential furnishings: bed, storage, TV point |
| Affordable, accessible food | A connected restaurant with table service and quick-service options |
| Vehicle shelter & security | Canopy awning infrastructure for covered parking adjacent to the complex |
| Privacy & dignity | Each module has its own entrance, no shared corridors or lobbies |
| Location flexibility | Modular construction allows deployment roadside, in nature, near gas stations |
The complex is composed of three distinct architectural modules, the rest room units, the central restaurant building, and the canopy road connection, each designed to function independently, but conceived to operate as a unified system. The modular logic allows the complex to be replicated at any roadside location with minimal site modification.
Individual sleep units, each ~8.21 × 4.4m, with private entrance, compact sleeping area, storage, and bathroom facilities.
12 × 4.6m dining space with kitchen zone and service bar. Capacity for 30+ seated guests with round-table social seating.
Sloped roof canopy structures for vehicle cover and pedestrian connection between modules along the road-side frontage.
Horizontal WPC (Wood-Plastic Composite) cladding in two-tone warm palette, unifying the complex visually while breaking massing.
Rain-screen cladding system with ventilated cavity, managing solar gain and condensation in Iran's extreme climate zones.
Each rest module is a self-contained unit measuring 8.21 m in width and 4.4 m in depth, compact enough to be economical, generous enough for a comfortable short stay. The floor plan separates sleeping and living functions cleanly, with a dedicated TV area, wardrobe storage, bathroom, and three single sleeping berths.
The module entrance is on the short facade, with a door width of 1 m and a small high window to maintain privacy. The building height is 4.5 m, providing ceiling clearance of approximately 2.5 m interior.
Four modules are deployed side-by-side in the standard configuration, with staggered placement in plan to create visual interest and a slight acoustic buffer between units.
| Element | Dimension |
|---|---|
| Module width | 8.21 m |
| Module depth | 4.4 m |
| Building height | 4.5 m |
| Interior ceiling | ~2.5 m |
| Entrance door | 1.0 × 2.1 m |
| High window | 1.85 × 0.7 m |
| Sleeping berths | 3 singles (4 m depth each) |
| Bathroom area | 2.2 × 0.9 m approx. |
| Roof structure | Lean-to, 0.54 m ridge slope |
The restaurant is the social heart of the complex, a 12 × 4.6 m building that provides food service, human contact, and a sense of place to travelers who have been isolated on the road for hours. The plan is organized with an open dining floor accommodating round tables for 4 to 6, a central service bar, and a kitchen zone to the rear.
The restaurant has a split-level volume with a bold glazed entrance on the front facade, a 4 m wide double-door with a clerestory window above, providing natural light into the dining room and creating a landmark presence on the road edge.
The kitchen and service area occupy the right-hand third of the plan, separated from the dining area by a counter. A separate WC and service door on the side elevation provides staff access.
| Element | Dimension |
|---|---|
| Total width | 12.0 m |
| Depth | 4.6 m |
| Dining area width | ~8.0 m |
| Kitchen/service zone | 3.0 × 4.6 m |
| Entrance door set | 1.5 × 2.1 m |
| Glazed entrance canopy | 4.0 m wide |
| Table type | Round, Ø 0.75 m (small) and Ø 3.5 m (feature) |
| Service bar depth | 0.86 m |
| Building height | 4.5 m |
The exterior cladding system was a critical design decision, it needed to perform in Iran's extreme temperature swings (from minus 15°C winters in the north to plus 45°C summers in the south), remain low-maintenance, present a warm and welcoming aesthetic, and be achievable within a budget accessible to middle-market clients.
The primary cladding material selected is a WPC (Wood-Plastic Composite) horizontal lapped siding board, a material that closely resembles natural wood grain in appearance while offering the dimensional stability, moisture resistance, and UV durability needed for an exposed roadside environment. Available in a range of colors and grain textures (Cedar Blend, Natural Blend, Rustic Blend, Arbor Blend among others), WPC allows the two-tone color split used across the complex to be achieved in a single material family.
The concealed-fastener system shown in the detail below allows clean, nail-free faces on all elevations, a detail that elevates the perceived quality of the structure significantly beyond its construction cost.
The cladding is installed as a rain screen system with a ventilated air cavity between the WPC boards and the exterior sheathing. This is critical for the thermal performance of the buildings. As shown in the Climate-Shield technical diagrams, cool air enters at the base of the cavity, is warmed by solar gain on the cladding face, and exits at the top through natural convection, reducing heat transfer into the building fabric and extending the life of the cladding by eliminating moisture trapping.
Rain screen ventilation concept: cool air enters at the base of the cavity between the WRB and the WPC siding, is warmed by solar gain on the cladding face, and exits at the top by natural convection.
Final selection was Cedar Blend / Rustic Blend two-tone, as shown in the 3D model renders below.
The massing models below show the full complex in context. The two-tone WPC cladding creates a visual rhythm across the connected volumes, the taller restaurant tower reads as anchor, the lower sloping-roof rest modules extend to the sides, and the transparent polycarbonate canopy panels link the whole ensemble along the road-facing elevation.
The massing deliberately avoids any form of "hotel" signage or iconography. The building reads as a contemporary roadside shelter, honest in its materials, identifiable in its form, approachable in scale.
This project is unusual in the portfolio of an industrial designer, it operates at architectural scale. But the approach was fundamentally industrial: defining the user, identifying the system, designing the module, specifying the material, and iterating through dimensions until the proportions, costs, and functional requirements were all satisfied simultaneously.
All room dimensions, window sizes, door positions, furniture layouts, and module configurations were developed independently by the designer. The civil engineering team at Syeh Sazane Mehr Gostar provided structural feasibility review and construction method consultation, but the design intelligence, spatial logic, and material specification originated with and were led by the industrial designer.

The Roadside Rest Complex demonstrates the capacity of industrial design thinking, system logic, user empathy, modular iteration, material intelligence, to address problems that are conventionally left to architecture or civil engineering alone.
The concept established a typology that did not previously exist in the Iranian road infrastructure context: a dignified, affordable, modular rest stop that could be deployed flexibly across diverse terrain and climate conditions, serving a segment of the traveling population that had been consistently underserved.
The rest unit can be deployed 2 to 8 in a row without design modification.
The WPC and timber frame system keeps build cost accessible.
Rain screen ventilation reduces cooling load across all Iranian climate zones.
Private entries, lockable rooms, and proper beds, not bunks or capsules.
The footprint and module logic works on flat roadside plots anywhere in the country.
