Guide to Commercial Building Types and Construction

By Design-Build

What are the Commercial Building Types and How Are they Constructed?

Commercial buildings come in all shapes and sizes. Whether it’s a sleek high-rise office or a neighborhood retail center, every structure begins with a clear vision and the right construction strategy. As a commercial general contractor, we partner with developers and businesses to bring these spaces to life. This guide outlines common types of commercial buildings and how they’re typically constructed, giving you insight into what sets each one apart. 

1. Office Buildings 

Types: Low-rise, mid-rise, and high-rise buildings used for business operations. 

Construction Approach:
Office buildings often prioritize flexibility, natural light, and energy efficiency. Steel or reinforced concrete is commonly used for the structural frame, while curtain walls or glass facades give these buildings their modern aesthetic. Interior build-outs vary depending on tenant needs and can include raised flooring, modular walls, or open-plan layouts. 

Example: Summit Design + Build recently completed 1040 W Fulton, a new five-story, 42,000 square-foot office building with ground-floor retail, a green roof, and basement parking located in Chicago’s Fulton Market District. Floors four and five serve as Summit Design + Build’s new headquarters. This project is a showplace of modern wood construction, as it is the first multi-story mass timber building in Chicago in 50 years. 

The building features a hybrid construction system that accommodates two floors of parking in the basement and first floor using Type I-A construction with fire separation, while the office floors utilize Type III-A heavy timber construction. The framing system includes glulam columns, girders, and beams, with steel columns and beams supporting the brick exterior walls. The floor assembly incorporates a two-inch topping slab, and the building is fully sprinklered. 

Summit chose heavy timber construction to honor the neighborhood’s meatpacking district history, where many buildings were originally built with raw milled heavy timber. The design and framing plan aligned perfectly with the use of timber, blending historic materials with modern construction methods.

2. Retail Buildings

Types: Strip malls, shopping centers, big-box stores, and standalone storefronts. 

Construction Approach:
Retail buildings are designed with visibility, foot traffic, and accessibility in mind. These structures are typically single-story and use steel or CMU (concrete masonry units) construction for cost efficiency. Large open floor plans, storefront glazing, and ample parking are key features. 

Example: Summit Design + Build completed an adaptive reuse project on a prominent two-story building along Oak Street, transforming it into a high-end retail store. The project included a full interior renovation featuring a glass floor system and 10 to 12 distinct retail environments with unique finishes requiring precise coordination. The exterior façade was fully replaced with a modern mix of curtainwall, stone panels, and metal panels. 

Despite an aggressive 6-7 month schedule, the team expertly managed long lead times for custom materials including the curtain wall, stone panels, and a two-story LED screen wall. Energy-efficient LED lighting was installed, and the design team preserved existing equipment where possible to reduce waste. This project exemplifies Summit’s ability to deliver sophisticated, quality retail spaces within tight timelines in some of Chicago’s busiest commercial corridors. 

3. Industrial Buildings

Types: Warehouses, distribution centers, manufacturing facilities, and flex spaces. 

Construction Approach:
Functionality is the top priority. These buildings often require high clear heights, wide column spacing, dock access, and heavy-duty flooring. Pre-engineered metal buildings (PEMB), tilt-up concrete panels, and steel framing are commonly used for speed, scale, and durability. 

Example: Summit Design + Build delivered a 91,000 square-foot, $24 million foodservice distribution facility for Testa Produce in the Chicago area. This project is on track to become the nation’s first foodservice distribution center to achieve LEED Platinum certification, incorporating numerous sustainable features such as a 45,000-square-foot barreled vegetated roof, solar-heated hot water, 180 photovoltaic solar panels, and a 238 foot, 750 kW freestanding wind turbine, the first of its kind in Chicago. 

The project revitalized a long-vacant brownfield site using innovative foundation solutions and overcame significant political and design challenges related to the wind turbine and rainwater harvesting systems. Safety was prioritized throughout, especially around a complex ammonia refrigeration system and contaminated soil. The facility reduces utility consumption by over 60 percent, uses energy-efficient LED lighting, and incorporates recycled materials throughout. Delivered on schedule despite union strikes and weather delays, this facility sets a new standard for environmentally sensitive industrial construction. 

4. Hospitality

Types: Hotels, motels, and resorts. 

Construction Approach:
Hospitality projects combine aesthetics with performance. The structure might be steel or concrete, especially in high-rise hotels, while wood framing may be used in smaller or suburban locations. Interiors often require high levels of finish, coordinated MEP systems, and amenities such as pools, kitchens, and conference rooms. 

Example: Summit Design + Build served as Construction Manager Agent for the Springhill Suites by Marriott at 2353 S Wentworth in Chicago’s Chinatown. This 146-room, six-story hotel features a four-story steel structure built atop an existing two-story concrete parking garage. 

The project overcame significant site logistics challenges due to limited access and crane placement restrictions. A 500-ton crane with a luffing jib extension was deployed to reach the full 400-foot building length, requiring steel erection to be sequenced in two phases. The building was engineered to support the crane when laid down overnight. Crane erection and dismantling involved closing portions of 24th Street and coordinating with city officials and neighbors. 

The project successfully topped out the steel structure and completed façade and interior work on schedule. The Springhill Suites opened as planned in early 2021, delivering a high-quality hospitality space in a dense urban environment. 

 

5. Healthcare Facilities

Types: Medical office buildings, urgent care centers, clinics, and surgical centers. 

Construction Approach:
These spaces must meet strict building codes and regulatory standards. Construction involves complex MEP coordination, infection control planning, and specialized build-outs for medical equipment. Speed to market and patient comfort are often top priorities. 

Example: Summit Design + Build completed the build-out for Prenuvo, a cutting-edge medical imaging clinic in Chicago. The project required precise coordination of advanced medical equipment installation, strict adherence to healthcare regulations, and meticulous MEP integration to ensure a clean, patient-friendly environment. The design emphasized patient comfort and operational efficiency, delivering a high-tech facility on an accelerated timeline. Summit’s expertise in healthcare construction ensured that Prenuvo’s specialized needs were met, creating a space that supports advanced diagnostics in a welcoming atmosphere. 

6. Multifamily Residential

Types: Apartment complexes, condominiums, and mixed-use buildings. 

Construction Approach:
Multifamily construction varies by scale. Low- to mid-rise projects often use wood-frame construction over a concrete podium. High-rises require reinforced concrete or steel framing. Soundproofing, fire ratings, and egress paths are major considerations. 

Example: Located in Chicago’s West Loop, 1400 Monroe offers 42 luxury new-construction residences featuring two- and three-bedroom units with designer finishes. The building’s gray brick cladding and matte metal accents reflect the neighborhood’s industrial character. Interiors include nine-foot ceilings, oversized loft-style windows, bathrooms with high-end fixtures, custom kitchens equipped with Thermador, Bosch, and Franke appliances, and smart home technology. 

The project team overcame design and construction challenges through strong collaboration, ensuring high-quality finishes while integrating modern conveniences such as elevator access, garage parking, storage lockers, a bike room, and dog-washing services. Private balconies and terraces enhance urban living. The project was completed efficiently, meeting owner expectations for budget and schedule while delivering a distinctive residential community that blends thoughtfully with its vibrant surroundings. 

7. Mixed-Use Developments

Types: Buildings that combine retail, office, and residential uses. 

Construction Approach:
These projects require careful zoning coordination and structural planning to support different uses on different levels. Podium-style construction is common, with commercial on the ground floor and residential or office space above. Shared utilities, parking, and amenities introduce added complexity. 

Example: Summit Design + Build completed a mixed-use project featuring a 120-unit apartment building in Evanston. The building includes a variety of unit types — studios, one and two bedroom apartments — with amenities such as a fitness room, co-working spaces, and a roof deck equipped with grills, a dog run, pergola, and seating areas. Ground floor retail space opens onto an exterior patio, enhancing street level engagement. 

Built on a tight site occupying the entire lot, the project required precise crane maneuvering to erect the full 22,000 square foot floor plates. Sustainability was prioritized through multiple green roofs and on site rainwater detention and infiltration tanks, aiming for Green Globes certification with two globes. Located along Main Street and adjacent to a Metra line, this development provides much needed housing with excellent transit access, positively impacting the community. 

Final Thoughts 

Understanding the different types of commercial buildings helps owners, developers, and tenants make smarter decisions from the start. Each project has unique design, engineering, and construction requirements, so choosing the right approach—and the right contractor—is key to success.

Design-Build vs. Design-Bid-Build: What’s the Difference?

By Design-Build

Design-Build vs. Design-Bid-Build: What’s the Difference?

When developers take on a new construction project, selecting the right project delivery method is critical to achieving the right balance of cost, speed, and control. Two widely used approaches are Design-Bid-Build (DBB) and Design-Build (DB). While they sound similar, they differ significantly in process, risk allocation, and efficiency.

At Summit Design + Build, we specialize in both Design-Build and Design-Bid-Build. We work closely with developers to determine which method best aligns with their project goals. 

Here’s a breakdown of each approach and when it makes the most sense.

The Market

In a Design-Bid-Build process, the project follows three distinct phases:

  1. Design Phase – The developer hires an architect to create detailed construction documents.
  2. Bidding Phase – Once the design is complete, contractors submit competitive bids, and a general contractor is selected.
  3. Build Phase – The contractor constructs the project based on the architect’s plans.

Pros of DBB:

  • Clear separation of responsibilities between architect and contractor.
  • Competitive bidding may drive down initial construction costs.
  • Well-suited for projects where design control is a top priority.

Cons of DBB:

  • Longer project timelines due to the sequential nature.
  • Potential for design conflicts, leading to costly change orders.
  • Developers may need to manage disputes between the architect and contractor.

When DBB is a Good Fit:

Design-Bid-Build works best when the project has well-defined design requirements and developers want to compare contractor bids before selecting a builder. It’s also a strong option for projects with strict regulatory requirements or municipal approval processes that require full design completion before bidding.

Design-Build (DB): A More Integrated Approach

In a Design-Build process, the developer partners with a single entity (typically a general contractor or design-build firm) that oversees both design and construction. This integrated approach fosters collaboration, improves efficiency, and often reduces overall costs.

Pros of DB:

  • Faster project completion since design and construction phases overlap.
  • Greater collaboration minimizes conflicts and unexpected costs.
  • A single point of accountability reduces risks for the developer.

Cons of DB:

  • Less direct control over design unless expectations are clearly defined upfront.
  • Requires trust in the Design-Build team’s ability to balance cost, quality, and vision.

When DB is a Good Fit:

Design-Build is ideal for developers looking to streamline project delivery, reduce risk, and compress timelines. It works especially well for complex projects, fast-track schedules, and when developers want a more collaborative, turnkey solution.

Design-Build Construction: Everything You Need to Know

By Design-Build

Design-Build Construction Guide

 

What is Design-Build Construction?

Design-Build is a construction delivery method where the owner signs one contract for both architectural design services and physical construction. This approach simplifies collaboration, communication, and coordination.

In design-build construction, the architect and general contractor collaborate from project inception, offering unified recommendations tailored to the owner’s needs.

All team members address changes collectively, fostering innovative problem-solving without blame-shifting. Besides single-source contracting, the collaborative culture is equally vital.

Benefits of the Design-Build Approach

  • Single Point of Contact: The owner has one point of contact (the general contractor) for questions and input.
  • Minimizes Owner Risk: More risk falls on the design-build contractor, protecting owners from unexpected costs from design errors and construction delays.
  • Single Contract: Simplifies project management and reduces the potential for conflicts.
  • Emphasis on Collaboration: Increased early-stage collaboration between the general contractor and other team members leads to significant cost savings and a more efficient schedule.
  • Unified Recommendations: General contractors and architects work as a team, providing unified and efficient recommendations.
  • Reduction in Change Orders: Single-source responsibility minimizes costs and streamlines schedules.

Comparison with Traditional Construction Methods

  • Design-Bid-Build: The owner hires the architect first to develop scope, program, and design, then the project goes out to bid to General Contractors. This separation can lead to siloed communication and costly change orders.
  • Construction Management at Risk (CMAR): A construction manager oversees the project, but design and construction are still separate phases.
  • Integrated Project Delivery (IPD): A collaborative approach involving shared risk and reward among all parties but can be complex to implement.

 

The Design-Build Process

Step-by-Step Guide:

  1. Project Initiation: Define project goals, initial consultation, and create a detailed project brief.
  2. Site Selection: Identify, analyze, evaluate, and secure the optimal site.
  3. Project Conception/Feasibility: Conduct feasibility studies, develop a preliminary budget, assess risks, and seek client approval.
  4. Team Selection: Issue RFQs, RFPs, evaluate proposals, and select the design-build team.
  5. Project Planning/Preconstruction: Hold kickoff meetings, develop detailed plans, and create a risk management plan.
  6. Design: Create schematic designs, develop detailed designs, update cost estimates, and prepare construction documents.
  7. Construction: Mobilize the site, procure materials, execute construction, implement quality control, and conduct regular inspections.
  8. Completion: Perform final inspections, create and address a punch list, conduct a client walkthrough, provide as-built documentation, and formally hand over the project.

Traditional Construction vs. Design-Build Construction Process
