Converting a warehouse into an office space is a phenomenal way to leverage high ceilings, open floor plates, and industrial character. Many world-class and regional architecture firms specialize specifically in industrial adaptive reuse and commercial conversions.
Major architectural firms and practices renowned for transforming industrial and warehouse spaces into cutting-edge workplaces include:
DLR Group : One of the largest integrated design and architecture firms in the U.S., heavily experienced in commercial adaptive reuse, urban revitalization, and breathing new life into old warehouse/manufacturing stock.[]()
For a warehouse-to-office conversion, you want an architecture firm with adaptive reuse experience — specifically, converting industrial buildings into modern workplaces while preserving useful original features such as exposed brick, steel trusses, concrete floors, and high ceilings.
Assuming your project is in the Grand Prairie / Dallas–Fort Worth area, I found several firms worth contacting. The strongest starting point is to look at firms with documented warehouse-to-office projects, not just general commercial architecture experience.
Architecture firms to consider
1. Corgan
(Documented warehouse-to-office project)
Corgan converted a 1940s Dallas warehouse into a boutique office, retaining industrial character while adding glass-fronted offices, natural light, conference space, and an outdoor patio. This is a close match to your project.
Quorum specializes in renovations and adaptive reuse. Its own office occupies a converted 1930s warehouse, with exposed steel beams, brick walls, clerestory windows, and a new mezzanine.
The firm transformed historic Foch Street warehouse buildings into a mix of office, retail, and restaurant spaces. Its portfolio also includes the Armour Building, a historic industrial property being converted into creative office space.
A firm to consider for commercial renovations and adaptive reuse, particularly if the project involves historic preservation, complex existing conditions, or mixed-use redevelopment.
A boutique architecture and interiors studio whose stated specialties include adaptive reuse, historic preservation, mixed-use, and urban design. Worth exploring if you prefer a smaller, principal-led design practice.
Feasibility and existing conditions: structural capacity, roof condition, foundations, and whether the existing building can support your intended office layout.
Building systems: HVAC, electrical service, plumbing, fire sprinklers, emergency exits, and energy performance.
Code compliance: change of occupancy, accessibility requirements, fire separations, and required parking.
Cost control: a preliminary feasibility study and realistic renovation budget before committing to full design.
Comparable projects: at least two completed warehouse-to-office conversions, ideally similar in size and age to yours.
My recommendation
I'd start by interviewing Corgan and Quorum Architects, then include Bennett Partners for another comparison. Their documented warehouse reuse projects make them relevant candidates, though fees, current availability, and project fit still need to be confirmed.
One question that would help narrow this down: Approximately how large is your warehouse?
When looking to repurpose an industrial warehouse into a high-performing office space, you'll want architecture and design firms that specialize in historic preservation, structural adaptation, and innovative workplace interior integration.
Top Adaptive Reuse Design Experts
Gensler: A global powerhouse renowned for workplace strategy and large-scale building conversions. They feature specialized proprietary tools (like Conversions+) and deep expertise in evaluating industrial and commercial structures for cutting-edge office environments.
MVRDV: An internationally acclaimed Dutch firm celebrated for bold, socially-focused adaptive reuse projects—including transforming old industrial and post-war structures into avant-garde workspaces.
To help narrow down which firm might be the ideal fit, could you share:
The approximate square footage and location of the warehouse?
Your target timeline and budget scale?
Whether you are looking for a local regional firm or a global practice?
Assuming you’re in the Washington, DC / Northern Virginia area (based on your search context), I’d start with architects and workplace-design firms that have adaptive reuse, industrial conversions, and office/workplace experience. A warehouse-to-office project usually benefits from a team that can handle change-of-use/code review, historic or structural constraints, daylighting, MEP upgrades, and workplace strategy.
Here are some firms to consider:

Retrofitting commercial buildings to achieve net-zero energy typically involves specialized building-performance firms, energy-service companies (ESCOs), mechanical engineering consultants, and contractors that combine energy efficiency upgrades with on-site renewable energy systems.
A net-zero retrofit generally aims to reduce a building's energy demand through improvements such as HVAC modernization, better insulation, high-performance windows, LED lighting, and smart building controls, then offset the remaining annual energy use with solar power or other renewable energy.
The right provider depends on whether you're retrofitting an office tower, warehouse, hotel, retail property, or an entire portfolio—and whether you need a single turnkey contractor or a team of specialists.
Companies to consider
Here are several providers worth investigating, including firms serving South Florida and companies with broader U.S. coverage.

5. Self Reliance, Inc.
Markets turnkey net-zero energy systems and retrofit services for commercial and industrial buildings in the U.S. and Canada. Ask for recent project references and documented annual energy performance when evaluating this option.
These local providers may be useful for assessments, engineering, and implementation:
ecofi — Commercial property energy and water efficiency, smart controls, and sustainability implementation. Phone: (786) 600-0620.
FloridESCo, LLC — Energy-service company with turnkey energy projects and building commissioning capabilities. Phone: (305) 663-7285.

These local firms have relevant capabilities, but you should confirm whether they can deliver a complete net-zero retrofit or would coordinate with additional contractors.
How to choose a net-zero retrofit provider
Before hiring, ask each company for:
A whole-building energy audit and modeled energy-use baseline.
A proposed pathway to net-zero annual site energy, including solar feasibility and storage where appropriate.
A detailed capital budget, projected energy savings, incentives, and payback period.
References from completed retrofits of comparable size and building type.
A measurement and verification plan to demonstrate actual results after construction.
One important distinction: net-zero energy means annual energy consumption is balanced by energy generation or qualifying energy procurement under the chosen accounting method. Net-zero carbon emissions is a different target and may require additional measures.
Let me narrow this down
Are you looking for providers for a building in Miami/South Florida, elsewhere in the U.S., or internationally? And is it an office building, warehouse, hotel, retail property, or another type of commercial building? I can then focus on firms that are best suited to deliver the actual retrofit rather than just provide consulting.
: Offers comprehensive management software, microgrid setups, and enterprise-level building automation systems to optimize energy profiles and transition properties to net-zero.[](]()]()
Are there firms that handle the conversion of existing commercial buildings into net-zero energy facilities?
Converting an existing structure is often more complex than building a net-zero structure from scratch because it requires working within the constraints of an existing building envelope, older mechanical systems, and historical or structural limitations.
Types of Firms Involved in Net-Zero Conversions
Integrated Architecture & Engineering (A&E) Firms: Large global or regional firms (such as SOM, CannonDesign , or ) have dedicated sustainability practices that conduct whole-building life-cycle assessments (LCAs), energy modeling, and deep retrofits for commercial portfolios.[](]()]()
I need to find companies that specialize in retrofitting commercial properties to achieve net-zero energy status. Can you list some providers?

How I’d narrow the list
For an initial shortlist, I’d ask each firm for:
3 examples of warehouse/industrial-to-office conversions
Experience with your jurisdiction’s zoning and permitting
A test-fit study (how many workstations, meeting rooms, amenities, etc. fit)
Experience coordinating structural, MEP, fire/life safety, and energy upgrades
Whether they provide workplace strategy/interior design or partner with a specialist
If you share the warehouse location (city/state), approximate square footage, building age, and whether it’s a historic structure, I can narrow this to a more targeted list of firms that fit the project.
Energy Service Companies (ESCOs) : Specialized firms (such as Johnson Controls, Siemens, and Honeywell) handle performance-contracting retrofits where guaranteed energy savings fund the modernization of legacy mechanical and electrical equipment.
Specialized Architectural & Engineering Firms : Design-focused and sustainability-driven practices like McLennan Design plan and engineer deep-energy retrofits—such as transforming legacy 1970s structures into fossil fuel-free, net-zero environments.[](https://regeneration.org/nexus/buildings)
If you can share the location, approximate square footage , and current primary heating fuel of the commercial property, I can help narrow down the specific local incentives, regional ESCOs, or engineering firms best suited for your project.
Energy Service Companies (ESCOs) and Sustainability Consultants: Organizations that partner with property owners to audit, finance, and implement large-scale energy efficiency measures, often guaranteeing energy savings to fund the transition.
The Conversion Process Typically Includes
Energy Modeling & Auditing: Assessing the current energy use intensity (EUI) of the commercial building.
MEP (Mechanical, Electrical, and Plumbing) Decarbonization: Replacing fossil-fuel boilers and aging HVAC units with high-efficiency all-electric heat pumps and automated energy management systems.[](https://wrightarchitectspllc.com/sustainable-architecture-firm/)
If you have a specific building type (e.g., a mid-rise office, a retail space, or an industrial warehouse) or a geographic location in mind, I can help point you toward regional firms or case studies matching your project.
Yes. Firms now offer end-to-end commercial-building decarbonization/retrofit services, including energy audits, engineering, HVAC/electrical upgrades, controls, renewables, financing, construction, and measurement.
Examples include:
CMTA — zero-energy/zero-carbon building design and performance contracting.
Ameresco — deep-energy retrofits with in-house engineering, construction, O&M and measurement/verification.
Effectiv — specifically offers commercial net-zero energy master planning and implementation.
Arup / WSP — large engineering/consulting firms specializing in existing-building retrofit and portfolio decarbonization.
For a commercial property owner wanting one firm to take an existing building from assessment → design → financing → construction → verified net-zero performance, ESCO/design-build firms are probably the category to investigate first.
