Our Story
From New Zealand to the United States
Built Seas Containers began its journey in New Zealand, where we established ourselves as a trusted supplier of shipping containers and portable buildings. For over 10 years, we served businesses, contractors, and homeowners with premium-quality containers, flat-pack cabins, steel offices, and portable welfare units — building a reputation for quality, honesty, and outstanding service.
Driven by growing demand from North American clients and the opportunity to bring our unique expertise to a new market, we expanded our operations to the United States. Today, Built Seas Containers proudly serves customers from coast to coast — bringing the same commitment to competitive pricing and customer-first service that made us a leader.
Whether you need a secure storage container for a construction site, a flat-pack office for a remote project, or a welfare block for your workforce, our team has the experience and the national logistics network to deliver — fast, reliably, and at a price you’ll be happy with.
- Competitive, transparent pricing — no hidden fees, ever
- 10+ years of hands-on industry experience across two continents
- Every container graded, inspected and clearly described before sale
- Depots across all US states for faster, more affordable delivery
- Dedicated support team — Monday to Friday, 8AM–6PM
