Capacity-led accommodation
Seating, sleeping, hygiene and storage are derived from approved occupancy rather than a generic room size.
Illustrative concept 02
Collective residence with a shared protected area
A developer or residential operator wants one shared protected area for two apartment buildings. It must accommodate the nominated residents, remain discreet and be manageable after handover.
- Residential context
- Two buildings with approximately 17 apartments
- Apartment size
- Approximately 100–130 m² each
- Protected capacity
- Confirmed from occupancy, local rules and the operator model
- Options compared
- New-build integration, connection to an existing development, or standalone shared structure
Client requirement
What the client needs.
- A capacity and access model residents can understand
- Safe and accessible entry for nominated occupants
- Essential air, lighting, water, sanitation and communication
- Clear responsibilities for developer, operator and residents
- A workable maintenance, testing and replacement plan
Decisions
What feasibility must establish.
- Who receives an assigned place and how is attendance managed?
- Which local requirements define capacity and equipment?
- Who owns, inspects and pays for shared systems after completion?
- How do occupants reach the area safely from each building?
Proposed concept
A practical protected scope, shaped by real needs.
Accessible use
Access and priority rules account for children, older residents and people with limited mobility.
Shared-service strategy
Essential services are sized from the approved occupancy and protected-operation target.
Long-term ownership
Inspection, testing, training, replacement and service-charge responsibilities are assigned before handover.
Deliverable
Feasibility Study / Initial Mandate
The mandate creates a decision-ready basis for specialist design and project delivery.
- Resident, operator and capacity brief
- Review of site, buildings and available technical information
- Comparison of arrangements and connection points
- Functional room, access and system schedule
- Preliminary protected-scope construction budget and programme
- Responsibility, maintenance and client-led permitting interface plan
- Recommendation for detailed design and delivery
Initial Mandate / Feasibility Study
Starting fees
The final proposal reflects size, location, available information, specialist input, confidentiality requirements and required outputs.
| Integrated into a planned development | From CHF 25'000.- |
|---|---|
| Connected to an existing development | From CHF 35'000.- |
| Standalone shared structure | From CHF 32'500.- |
Scope note:
Capacity, protection performance and required equipment depend on the local legal framework and agreed operating brief. The study prices only the shared protected scope and its interfaces, not the apartment buildings.
