Plan your self-storage layout

Before choosing building dimensions, consider who will use the facility, what they will store and how they will access their units.

Planning detail What to discuss
Unit mix Intended uses, proposed unit dimensions and door requirements.
Customer access Drive-up or interior access and how vehicles and people will move through the property.
Climate control Insulation and environmental-control needs, including who supplies and installs the required systems.
Development phases What you plan to build first, what may follow and how future phases affect access and infrastructure.
Supporting spaces Offices, maintenance areas and other spaces needed to operate the property.
Project scope Who provides the building components, site work, installation and operating systems.

Self-storage building questions

Can I plan for more buildings later?

Yes, future development can be part of the initial planning discussion. Coordinate building placement, access and supporting infrastructure with your project team. The feasibility of later phases depends on your site and proposed development.

Is climate control included in the building package?

Confirm the scope in your quote. Climate-controlled storage needs an appropriate building enclosure, insulation and mechanical systems. Do not assume heating, cooling or humidity-control equipment is included in the steel building package.

Can storage units have different sizes?

Bring your proposed unit mix and access requirements to the design discussion. The configuration, door openings and available options need to be confirmed for your project.

What affects the cost of a self-storage building?

Dimensions, unit layout, openings, location, engineering and selected features influence the building quote. Site work, foundations, utilities, installation and operating systems may be separate costs.

How do I get comparable quotes?

Provide each supplier with the same location, dimensions, unit mix, openings and project scope. Ask each to identify included components, exclusions and responsibilities so you can compare equivalent proposals.

What Customers Are Saying

"I shopped around, and in the end, selected Olympia Steel Buildings. This was my first steel building and I am not a contractor. I wanted to do as much as I could to keep costs down an enjoy the experience. With that said I had a lot of pre-sales/design questions to minimize the unknowns.... The entire building went together very well... Took about 6 weeks to complete with help from family and friends. Great People, Great Product."

M. S.

"I purchase a 30x40 building from Olympia Steel Bldgs and was very impressed with the whole process, from order, delivery to final construction. They referred me to a crew that were very professional and knowledgeable and gave me a great deal on insulation and labor costs. The building is extremely well constructed and I was able to add extra roll-up doors from a local vendor and it looks great!... If I ever move and need another building, I will be calling Olympia! Thanks Again"

D. R.

"I had a fantastic experience with Olympia. After 6 months of dealing with another company that failed to deliver, I reached out to Olympia and got a BETTER building for the same price as the other company. It was delivered quickly with all the pieces, parts, and hardware... I was able to put the 25'x36'x10' building up myself with a little help from friends and family. I'm now enjoying my third winter of parking my cars and my boat inside, and it's GREAT!... I cannot recommend the building or company more highly!"
