What Is Design-Build? How It Works for a Chicago Home Renovation
Most homeowners hire a designer to draw the project, then a contractor to build it — two companies, two contracts, and a gap in the middle where things go wrong. Design-build collapses that into one: a single firm designs and builds your renovation, with one team accountable from the first sketch to the final walkthrough. Here's exactly how it works, how it differs from the traditional model, and why it fits Chicago's vintage homes and condos.
Design-build, in one sentence
Design-build is a way of delivering a renovation in which one firm handles both the design and the construction under a single contract — so the same team that draws your kitchen is the team that builds it. That's the whole idea. Everything else in this guide is a consequence of that one structural choice.
To see why it matters, it helps to know what it replaces. The traditional model is called design-bid-build, and it has three separate steps. First you hire a designer or architect to produce drawings. Then you take those drawings out to contractors, who bid on the work. Then the winning contractor builds it. Three steps, three relationships, and a seam between the design and the build where responsibility splits.
That seam has a cost. The designer draws something beautiful without firm pricing behind it. The contractor prices it and says it can't be built that way for that budget. Now you're standing between two parties who don't answer to each other, translating, renegotiating, and absorbing the delay. When something on site doesn't match the drawings, the designer blames the builder and the builder blames the designer — and you're the one paying either way.
Design-build closes that seam by putting design and construction inside one firm with one contract. The people drawing your project already know what it costs to build, because they're the ones who'll build it. The design is realistic from day one. There's no bid gap, no handoff, and no finger-pointing — just one team you can hold accountable for the result. This guide explains how that works phase by phase, where the model genuinely helps versus where the traditional route is fine, and why design-build is especially well-suited to Chicago's older homes and condo buildings.
How design-build works, phase by phase
A design-build renovation runs in four phases. The defining feature isn't the phases themselves — most projects have similar stages — it's that one firm carries you through all four, so nothing gets lost in a handoff between companies. Here's what each phase actually involves.
Discovery & Consultation
It starts with a conversation about what you want, what you can spend, and what your space and building will allow. The critical difference from the traditional model: the team that will eventually build the project is in the room from this first meeting. So the early ideas are grounded in real construction knowledge — your budget and your building's actual conditions shape the vision before a single line is drawn, instead of after.
Design & 3D Rendering
The design develops — layout, cabinetry, fixtures, and material and finish selection, often with samples you see and compare in person at the studio. Before anything is ordered or demolished, you review photorealistic 3D renderings of the finished space. This is the cheapest possible moment to change your mind, and it's where design-build shines: because the same firm will build it, every design decision is checked against buildability and cost as it's made, not after.
Pre-Construction
The approved design is converted into firm, fixed pricing — no bidding-out to strangers, because the builder is already on the team. The firm pulls city permits and, for condos, prepares the HOA or board alteration approval package. Long-lead materials get ordered now so they're on site when needed. By the end of this phase, you have a price you can rely on, a schedule, and the approvals in hand to start.
Construction & Closeout
One team builds the project, schedules and manages every trade, and keeps the work matched to the design and the budget. Because the people building it are the people who designed it, questions get answered on the spot rather than routed back to a separate designer. The phase ends with a final walkthrough and handover of the finished space — one point of contact the entire way through.
One team carries all four phases
In the traditional model, the design phases belong to one company and the build phases belong to another, with a bid process and a handoff in between. In design-build, the same firm runs all four phases under one contract. That continuity — not any single phase — is what removes the gaps where renovations usually lose time and money.
Design-build vs. hiring a designer and contractor separately
The clearest way to understand design-build is to compare it directly to the traditional design-bid-build route on the things homeowners actually feel during a renovation. Here's how the two models differ on each.
-
01
Accountability Design-bid-build splits it: when something goes wrong, the designer and the contractor can each point at the other, and you arbitrate. Design-build puts accountability with one firm — there's a single name responsible for both the plan and the result.
-
02
Budget reality In the traditional model, you can finish and fall in love with a design before any contractor prices it — then discover it's well over budget. In design-build, the design is priced against real construction costs as it develops, so the number is grounded from the start.
-
03
Speed and changes Separate hires mean every change is a round trip between two companies. Design-build keeps design and build in one team, so adjustments are handled internally and quickly — which matters most once construction is underway.
-
04
Who manages it In design-bid-build, coordinating the designer and the contractor often falls to you. In design-build, the firm manages the whole project; you have one point of contact instead of being the middleman.
-
05
When the traditional model still wins Design-bid-build isn't wrong. If you already have a trusted architect with a strong vision, or you want competitive bids on a fully-specified set of drawings, the separate route can be the right call. Design-build's edge is greatest when design and construction decisions are tightly linked — which is most residential renovations.
The question that reveals which model you're really getting.
A design-build firm answers that the design was priced against real build costs throughout, so the gap is small and the same team adjusts the plan with you. The separate-hire route often sends you back to renegotiate with a contractor — or to redesign — because the person who drew it never had to build it. The answer tells you instantly whether you've hired one accountable team or signed up to be the middleman between two.
Why design-build fits Chicago homes and condos
The design-build advantage is real anywhere, but Chicago's housing stock and rules make it especially valuable. The factors that complicate renovations here are exactly the ones a single coordinated team handles best.
Vintage North Side buildings
Lincoln Park, Lakeview, Wicker Park, Bucktown, and Roscoe Village are full of greystones, two-flats, and older condos with narrow footprints, original load-bearing walls, and quirks no template accounts for. A design-build team designs with those realities in hand — so the plan fits the building, not a generic floor plate. In the separate-hire model, a designer unfamiliar with the building can draw something a contractor later has to unwind.
Aging building systems
Many vintage Chicago buildings still hide galvanized supply plumbing or knob-and-tube wiring behind the walls. A renovation often means those systems get touched — and a design-build firm anticipates that in both the design and the price, because the people drawing the project are the ones who'll open the walls. That foresight is where mid-project surprises get avoided.
Condo boards, HOAs, and city permits
A large share of Chicago projects are in condos and high-rises, which adds board alteration approvals, insurance certificates, restricted work hours, and elevator logistics on top of city permits. Condo board approval alone can add roughly two to six weeks before a permit is even submitted. A design-build firm owns that entire approval process as part of pre-construction, so it doesn't fall on you and doesn't stall the schedule.

Where design-build becomes tangible
Design-build is easiest to experience in person. At our Lincoln Park Design Studio at 2315 N Southport Ave, you see real cabinetry, countertop, and tile samples, work with an in-house designer who plans around your actual building, and review a 3D rendering before committing — all from the same firm that will build the project. That's the design-build model made visible: one place, one team, design and construction together.
How Assembly Squad runs design-build
Assembly Squad has been a design-build firm since 2013, with 500+ completed Chicago projects. In practice that means everything in this guide happens under one roof: you meet our in-house designer, develop the design and review 3D renderings, get fixed pricing from the team that will build it, and we handle permits and condo board approvals — then the same firm constructs the project and walks you through the finished result.
Most projects begin at our Lincoln Park Design Studio on Southport, where the design experience and material showroom live in the heart of the North Side. For renovations downtown — Streeterville, River North, Gold Coast, the Loop — the same team works from our headquarters at 205 N Michigan Avenue. Two locations, one practice, one accountable team from first sketch to final walkthrough.
Common questions about design-build
What is design-build?
Design-build is a project delivery method where one firm handles both the design and the construction of a renovation under a single contract, with one accountable team from first concept to final walkthrough. It's the alternative to design-bid-build, where you hire a designer first and then separately hire a contractor to build the finished drawings.
What is the difference between design-build and design-bid-build?
In design-bid-build, you hire a designer to produce drawings, then put those drawings out to contractors to bid on and build — three separate steps with separate parties. In design-build, one firm does both under one contract. The practical difference is the design-to-build gap: design-bid-build splits responsibility between designer and builder, while design-build keeps it with one team and prices the design against real build costs from the start.
How does the design-build process work?
It typically runs in four phases. Discovery and consultation: goals, budget, and site assessment. Design and 3D rendering: layout, material selection, and renderings reviewed before construction. Pre-construction: fixed pricing, permits, and HOA or condo board approvals. Construction and closeout: one team builds, manages the trades, and delivers the finished space.
Is design-build cheaper than hiring a designer and contractor separately?
Not automatically, but it tends to avoid the costly surprises of the separate-hire model. Because the same team designs and builds, the design is priced against real construction costs from the start, so you're less likely to finish an expensive design only to learn no contractor can build it for your budget. It also reduces change-order friction and the carrying costs of a longer, less coordinated timeline.
What are the advantages of design-build?
A single point of accountability, a design priced against real build costs, no handoff gap between designer and contractor, faster changes during the project, and one coordinated timeline. For homeowners, it usually means fewer surprises and one team to hold responsible for the result.
Why is design-build a good fit for Chicago homes and condos?
Chicago's North Side has many vintage greystones, two-flats, and older condos with narrow footprints, original walls, and aging galvanized plumbing or knob-and-tube wiring. A design-build team designs with those build realities in mind, so the plan fits the building and the budget. It also streamlines the condo board approvals, insurance certificates, and city permits Chicago projects require, because one firm owns that process end to end.
Does a design-build firm handle permits and condo board approvals?
Yes — handling city permits and HOA or condo board alteration approvals is typically part of the service, included in the pre-construction phase. In Chicago, condo board approval can add roughly two to six weeks before permits are even submitted, so having one firm own that process keeps the timeline on track.
What types of projects use design-build?
Kitchen and bathroom remodels, condo and whole-unit renovations, basement finishing, home additions, and whole-home renovations. It's especially valuable on projects with coordination complexity — condos, vintage buildings, and whole-home work where design and construction decisions are tightly linked.
