Planning a Flex Space or Showroom Buildout in Houston
Flex buildings are a common sight across the Houston area, especially along major freeways and in business parks. A typical flex suite combines finished office or showroom space at the front with warehouse space and a grade-level or dock door at the back. They serve contractors, distributors, design firms, small manufacturers, fitness studios and many other businesses that need a mix of customer-facing and working space.
Flex and showroom buildouts can be simple or complex depending on the tenant. This guide walks owners, tenants and investors through the planning steps. It is general information, not legal or engineering advice. Work with your design team and contractor on the details for your space.
Define the mix of space
Start by deciding how the suite will be split:
- Showroom: Display area for products, often with storefront glass and higher-end finishes.
- Office: Desks, conference rooms and break areas.
- Warehouse: Storage, light assembly or shipping.
- Support: Restrooms, storage closets and server rooms.
The mix affects HVAC, lighting, finishes, code requirements and cost. A suite that is mostly warehouse with a small office is a very different project from a large showroom with a small back room.
Storefront and glazing
Showrooms often benefit from large windows and storefront glass to attract drive-by customers. Plan:
- Glass type for Houston heat, glare and energy code
- Entry doors with accessible hardware
- Window film or shades to protect displays from sun
- Security film or other measures where theft is a concern
Envelope changes need to meet energy code requirements. The International Energy Conservation Code sets the framework, often documented with the Department of Energy's COMcheck tool.
Demising walls and suite layout
In multi-tenant flex buildings, suites are separated by demising walls. When suites are combined or split, walls may need to be built or removed. Depending on uses, these walls may need fire ratings. The International Building Code sets separation requirements. Our warehouse office buildout questions guide covers common layout decisions.
HVAC zoning
Showrooms and offices need full air conditioning, while warehouse areas may only need ventilation, fans or spot cooling. Plan:
- Separate zones or systems for showroom, office and warehouse
- Insulated walls between conditioned and unconditioned spaces
- Ventilation for any light manufacturing or finishing work
- Humidity control in showrooms with sensitive products
ASHRAE's standards guide ventilation design. Our guide to commercial rooftop HVAC replacement planning explains equipment decisions.
Lighting
Showroom lighting sells products. Consider:
- Track or accent lighting for displays
- Even general lighting in offices
- High-bay LED fixtures in warehouses
- Controls such as occupancy sensors and daylight sensors
The Department of Energy explains LED lighting basics, and our guide to commercial lighting and ceiling upgrades covers ceiling and fixture decisions.
Docks and grade-level doors
The warehouse side needs to work for deliveries:
- Grade-level doors for vans and pickups
- Dock-high doors for trucks, where available
- Dock levelers, bumpers and seals
- Clear paths from doors to storage
- Bollards to protect doors and walls
Our guide to warehouse floor slab and loading dock repairs covers dock work, and our warehouse mezzanine addition guide explains how to add storage or office space above the floor.
Fire protection and storage
Warehouse storage height and the type of goods stored affect sprinkler requirements. High-piled storage can require upgrades to existing sprinklers. Sprinkler design follows NFPA 13, and the Houston Fire Marshal's Office reviews plans in the city. Tell your design team what you plan to store and how high.
Accessibility
Showrooms and offices open to customers must meet the 2010 ADA Standards for entrances, routes, counters and restrooms. Our guide to ADA items to review in a buildout covers common issues.
Signage
Flex tenants often rely on building and monument signs. Sign approvals in the city go through Houston sign administration. Check landlord sign criteria and any deed restrictions before ordering signs.
Permits and certificate of occupancy
Flex and showroom buildouts usually need building, mechanical, electrical and plumbing permits, and a certificate of occupancy for the new use. The Houston Permitting Center explains requirements, and our guides to the buildout permit process and the certificate of occupancy for a lease space walk through each step.
Lease and deal considerations
Owners and tenants should agree on:
- Landlord work versus tenant work
- Improvement allowances
- Who owns and maintains HVAC and doors
- Restoration requirements at lease end
- Permitted uses, including any light manufacturing
Our guide to landlord work vs tenant work letters explains common terms. Have your attorney review the lease before signing.
Investor view: flex suites that lease well
For owners and investors, flex buildings can attract a wide range of tenants, but suites lease faster when the buildout fits common needs rather than one tenant's unusual requirements. Some owners build a small, finished spec office and restroom in vacant suites so prospects can picture themselves in the space. Others deliver a basic shell and offer an improvement allowance. Practical features that tend to appeal to many users include a clean, well-lit front office, at least one accessible restroom, insulated walls between office and warehouse, LED high-bay lighting, a working grade-level door and enough electrical capacity for light equipment. Our guide to commercial property renovation before lease-up explains how owners prepare vacant space for marketing.
Showroom finishes that hold up
Showrooms see customer traffic, product moves and frequent display changes. Durable floors such as polished concrete or commercial luxury vinyl, wall surfaces that can be patched and repainted easily and flexible lighting tracks let tenants refresh displays without a new buildout. Our guide to commercial flooring for high-traffic spaces covers flooring options.
Questions to ask contractors
- How will showroom, office and warehouse areas be zoned for HVAC?
- What storefront and glazing options fit our budget and energy code?
- Do sprinklers need upgrades for our storage plans?
- What dock or door work is needed?
- What permits and inspections apply?
- What is the schedule, including long-lead items?
Common mistakes to avoid
- Conditioning the whole warehouse by accident: Uninsulated walls let cold air escape.
- Ignoring storage height: High-piled storage can trigger sprinkler upgrades.
- Weak showroom lighting: Products look dull under poor light.
- Skipping sign criteria: Signs may need landlord and city approval.
