What City Self-Storage does
City Self-Storage, now operating as Green Storage (legal entity Green Storage AS, Norwegian org. no. 984801408), is a Norwegian self-storage operator serving private individuals and businesses across Norway, with subsidiary operations extending into Denmark and Sweden under parent holding company Self Storage Group AS. The company provides indoor storage units in nine standardized size tiers ranging from 0.5 m² (X-Small) to 31+ m² (King Size), plus drive-in container storage (3.4–13.8 m²) with direct vehicle access. Unit access is managed via digital app-controlled smart locks supplied by technology partner Janus, and customers self-manage bookings, account administration, and access through the proprietary "Mine Sider" (My Pages) online portal.
The business model is a self-service, product-led-growth rental operation. Customers book and manage storage entirely online through the greenstorage.com website, with no binding commitment and month-to-month flexibility. Pricing is tiered by unit size, starting at 79 NOK/month for the smallest units and reaching 4,719 NOK/month for King Size, with a promotional first-month rate of 1 NOK across all sizes. Revenue streams include recurring monthly rental subscriptions (the primary stream), an optional insurance add-on at 99 NOK/month, and a one-time establishment fee. The customer base is horizontal and consumer-led: the primary segment is private individuals (Privatlager) for moves, renovations, and life-transition storage, while the secondary segment comprises businesses (Bedriftslager) using units for inventory, equipment, archive, and seasonal storage.
Distribution is direct-to-consumer via the website, supported by educational blog content and a self-service FAQ funnel. The company claims the largest storage-location network in Norway, with facilities spanning Oslo, Bergen, Trondheim, Stavanger, Kristiansand, Drammen, Tromsø, Ålesund, and numerous secondary cities. Associated entities — Nugreen Services Norway AS, Green Storage A/S (Denmark), and Nugreen Services Denmark Aps — operate under the same group, executing a Nordic regional strategy. No revenue, headcount, management team, funding, or AI/ML capability data is disclosed in the source material.

City Self-Storage competitors and assessment
Company assessmentBroad incumbents
- CubeSmart: CubeSmart is a major US self-storage REIT with thousands of facilities. Comparable in standardized monthly-rental self-storage model and ancillary insurance offerings; benchmark for digital customer experience and unit-mix optimization.
- Public Storage: Public Storage is the largest US self-storage REIT, operating thousands of facilities. While US-focused, it is a benchmark comparable for unit economics, digital customer journey, and insurance-upsell mechanics that Green Storage is now deploying in Norway.
- Big Yellow Group: Big Yellow Group is a UK-listed self-storage REIT operating a national network of branded facilities. Comparable in offering standardized unit sizes, flexible month-to-month rentals, and ancillary services (insurance, packaging), though primarily UK-focused.
- SafeStore: SafeStore is a publicly listed UK self-storage operator with continental European expansion. Comparable self-storage rental model with multi-size unit portfolios, digital booking, and recurring-revenue economics; relevant benchmark for Green Storage's Nordic commercial trajectory.
- Extra Space Storage: Extra Space Storage is one of the largest US self-storage REITs with a growing European footprint. Comparable in business model (monthly recurring rental of standardized units) but at vastly larger scale; sets the bar for digital operations and unit-economics optimization in the category.
- Shurgard Self-Storage: Shurgard is Europe's largest publicly listed self-storage operator with hundreds of facilities across multiple countries. Directly comparable to Green Storage in core service (mini-storage units, monthly rentals, digital access) but with a broader pan-European footprint and deeper resources.
Emerging players
- Boxxo Self Storage: Boxxo is a Norwegian self-storage startup offering digitally enabled mini-warehouse storage with monthly subscriptions. Direct emerging competitor in the same Norwegian market with similar digital-first GTM motion targeting the same private-customer segment.
Direct peers
- Pink Storage: Pink Storage is a smaller Norwegian self-storage operator offering similar monthly-rental mini-storage units with online booking. Direct regional competitor targeting the same Norwegian private-customer and SMB segments as Green Storage.
- Lokal Norge: Lokal is a Norwegian self-storage operator with a comparable offering of mini-warehouse units, monthly subscriptions, and digital access across multiple Norwegian cities. Direct head-to-head competitor with overlapping product, pricing tiering, and target customer (private individuals and SMEs).
- Pelican Self Storage: Pelican Self Storage operates a network of self-storage facilities in the UK with comparable unit-size portfolios, monthly subscriptions, and digital booking flows. Comparable business model and customer-acquisition motion.
