Structural steel platforms that create usable overhead space according to an approved facility design.
Pre-wired, climate-controlled office options installed inside your facility, with scope and schedule confirmed by project.
Modular cleanroom options for pharma, manufacturing, and life sciences, with classifications and validation scope verified by configuration.
Guard booth and screening-station options with ballistic and wind ratings verified for the selected product and site.
Sound-attenuating and safety-enclosure options designed around documented equipment and facility requirements.
Modular wall systems that partition active space without permanent construction. Relocation is reviewed against the selected assembly and new layout.
Modular buildings — mezzanines, in-plant offices, cleanrooms, guard houses, and demountable walls — are factory-built structures installed inside or beside your existing facility in 2–4 weeks. They add usable space at a fraction of ground-up construction cost, with PE-stamped engineering, no lengthy permitting, and no production shutdown.
Same usable square footage — engineered and installed in weeks, for a fraction of a ground-up build, with no production shutdown.
Project-specific comparison
Reynolds verifies dimensions, use, materials, utilities, engineering, permits, site access, phasing, and lifecycle scope before comparing modular and conventional construction costs.
▮ Modular · New construction
Partition, enclose, or reconfigure space in days — not the months a permanent build takes. Demountable systems are fully relocatable, install without heavy structural permitting, and depreciate faster than fixed construction.
Unlock the vertical volume of your facility with structural steel mezzanines engineered around the approved use, loads, access, and facility layout.
Need an office on top?
A modular office can be evaluated as part of the approved mezzanine layout.
Project-specific analysis
This page does not publish an unreviewed cost model. Reynolds confirms dimensions, loads, use, engineering, permits, access, fabrication, installation, and cost inputs before presenting a comparison or payback estimate.

Floor space at capacity?
A mezzanine-supported office can be evaluated against the facility layout.
From guard booths to inventory cages, configure structures around the documented protection, site, and operating requirements.
More Storage
Your mezzanine creates floor space. High-density storage systems organize every square foot beneath it—doubling effective capacity with mobile shelving that eliminates wasted aisles.
Our engineers can assess your space, constraints, and timeline, then recommend the right modular solution.

Pre-engineered modular structures typically install for a fraction of ground-up construction, which runs $75-150 per square foot. Because they are factory-built and assembled on site in 2-4 weeks, you avoid extended permitting, general-contractor overhead, and production downtime. Reynolds provides a fixed engineered quote after a site assessment.
Most mezzanine installations are completed in 2-4 weeks. This includes design, engineering, manufacturing, and on-site installation. Complex projects may take 4-6 weeks.
Yes, our modular office systems are designed to be relocatable. If your operations change, the offices can be disassembled and moved to a new location within your facility.
Yes, all our mezzanine designs include PE-stamped structural engineering drawings. This ensures compliance with local building codes and OSHA requirements.
Our structural steel mezzanines support 125-500 PSF (pounds per square foot) depending on your requirements. We design each system for your specific use case—storage, production, or office space.
Reynolds designs, engineers, and installs ten modular building types across PA, NJ, DE, and MD: structural mezzanines, work platforms, catwalks, in-plant offices, cleanrooms, machine enclosures, guard houses, vestibules, shelters, and temporary/demountable walls. Every system is PE-stamped and OSHA/IBC compliant.

Our space planning experts can assess your facility and recommend the right modular solution—office, cleanroom, mezzanine, or specialized structure.
Our team will assess your facility, understand your constraints, and recommend the right solution—no obligation.
A Reynolds engineer walks your facility, measures clear heights and floor loads, and confirms code constraints.
We produce PE-stamped structural drawings sized to your use case — storage, production, office, or cleanroom.
Components are factory-built to spec while your operation keeps running — no on-site construction trades.
Our crew assembles on site in 2–4 weeks, OSHA/IBC compliant, with no production shutdown.
More capacity
Pair your modular platform with high-density mobile shelving to reclaim the floor space underneath — mobile aisles eliminate the waste of fixed-aisle racking.
