Custom Conex Shipping Containers

Turn a tough steel box into exactly what you need: a mobile office, a climate-controlled workspace, a retail kiosk, or a fully finished tiny home. Container Stop designs and builds custom Conex containers that solve real problems fast, reliably, and with an eye for long-term value.

What is a Custom Conex Container?

A Conex box is a standard shipping container repurposed and modified for on-site use. When you customize a Conex container you keep the core benefits—durability, portability, security—while adding features that make the space livable, usable, or sale-ready. 

Why customize instead of buying a stock unit?

Customizing gives you a container that works for your exact use case:

• Function tailored to need: storage with shelving, a workshop with power and lighting, or a climate-controlled lab.
  
• Faster and typically cheaper than ground-up construction for the same usable square footage.
  
• Portable—move it when your project moves.
  
• Strong resale value when done right.

How Much Does a Custom Conex Container Cost?

Costs vary widely depending on size and complexity. Think of pricing in three rough tiers rather than a single number:

• Basic modifications (doors, shelving, paint): lower cost, quick turnaround.
  
• Mid-level builds (insulation, HVAC, electrical, windows): moderate cost, weeks to complete.
  
• Full conversions (plumbing, full interior finishes, solar): highest cost, longer lead times.

Factors that influence price: container condition and size, selected materials and systems, required engineering/permits, and delivery logistics. We’ll provide a tailored estimate once we understand your needs.

Regulations & Compliance

• Local rules matter most. State codes are a baseline; city and county zoning often decide whether you can place or live in a container.
  
• Use matters. Commercial food units need health-department approval; habitable conversions typically require inspections and energy-code compliance.
  
• We help. We can produce drawings that meet permit requirements and offer guidance on site prep, foundation, and utility hookups.

Always check with your local building department early in the design phase.

Lead Times & Delivery

Typical timelines (approximate): simple shop mods can finish in 1–4 weeks; mid-level conversions often require 4–8 weeks; complex builds may take 8–16+ weeks. Delivery time depends on distance, site access, and whether special transport permits are needed.

Conex Container FAQs

Can a custom Conex be moved later?

Yes. Most are road-legal with the right chassis or transport setup. Permanent foundations are an option if you don’t plan to move.

Do you handle electrical and plumbing?

Yes. We install code-compliant systems and coordinate with local inspectors when needed.

Are custom containers insulated?

We offer several insulation systems (spray foam, rigid board, batts). Choice depends on climate and interior finish.
