GuardaEspaço — Peer-to-Peer Storage Space Marketplace for Portuguese Cities

Portuguese cities have a perfect storm for a storage marketplace: apartments are small (average Lisbon apartment is 70-85m²), families accumulate possessions, and formal self-storage facilities are rare, expensive, and located in industrial areas far from where people live.

The Problem

Portuguese cities have a perfect storm for a storage marketplace: apartments are small (average Lisbon apartment is 70-85m²), families accumulate possessions, and formal self-storage facilities are rare, expensive, and located in industrial areas far from where people live.

Meanwhile, thousands of Portuguese homeowners have empty garages, caves (basement storage), unused rooms in rural/suburban homes, and warehouse space sitting idle. There's no platform connecting these two groups.

The current alternatives are terrible:

  • Self-storage facilities (Shurgard, BlueSpace): €100-€300/month for a small unit, typically 15-30 min drive from city center, long contracts
  • Keeping stuff in parents' garage: Informal, creates family tension, unreliable
  • Throwing things away: Wasteful, especially for seasonal items, sports equipment, baby gear between kids
  • OLX/Facebook Marketplace: People post "tenho garagem para alugar" but there's no structured marketplace, no trust system, no insurance
