A design-build firm is a single company that holds both an interior design credential and an active general contractor license, which means one team manages your renovation from the first concept sketch through the final walk-through. In Scottsdale, where luxury renovation budgets often start at $150,000 and regularly climb past $1 million, that single point of accountability is why more homeowners are choosing design-build over hiring a designer and a contractor separately. Living with Lolo founder Lauren Lerner was recently profiled in Commercial Construction & Renovation magazine on exactly this model, in a feature called "Built as One," and the interview lays out why the gap between design vision and construction reality is the single biggest risk in a high-end renovation.

This post walks through what Lauren told Commercial Construction & Renovation about building Living with Lolo as a design-build firm, why she earned her Arizona ROC general contractor license on top of her interior design credential, and what that structure actually changes for a homeowner in Scottsdale, Paradise Valley, or Silverleaf. Because the magazine itself is a digital flipbook with no crawlable article text, we are publishing the substance of that conversation here so it is something you can actually search for, read, and reference.

The design-build model is not a niche preference anymore. According to the 2026 Houzz & Home Study, 93 percent of homeowners planning a project in 2026 expect to work with a professional, and general contractors are the single most commonly hired category at 55 percent. The National Association of Home Builders forecasts that residential remodeling activity will grow 3 percent in 2026 and another 2 percent in 2027, in inflation-adjusted terms, which points to sustained demand rather than a short-term spike.

Among firms that combine design and construction specifically, the Houzz Pro Industry Barometer reported that design-build remodelers entered the third quarter of 2026 with an average backlog of 6.2 weeks, up from 5.8 weeks a year earlier, and design-build companies remained more confident than build-only firms, with a forward-looking activity index of 63 compared to 59. Translated for a Scottsdale homeowner, that means design-build firms are booking further out and reporting steadier client confidence than contractors who only build from someone else's plans. National medians almost always understate what Living with Lolo clients spend on a full-scope renovation, and that gap between the average national project and a true Scottsdale luxury renovation is itself useful data if you are budgeting for one.

Lauren Lerner founded Living with Lolo in 2017, after several years in retail and a pull toward design she could not ignore. She started as an interior designer, the way most firms do, and quickly ran into the same problem that pushed her toward the general contractor license: clients were being handed off between their designer and their contractor, and when something went sideways, each side pointed at the other. Projects went over budget, over schedule, and under-delivered on the original vision.

Her answer was to close that gap entirely. She earned her Arizona ROC general contractor license so Living with Lolo could own the entire process, from the first concept sketch through the final walk-through, without a translation layer between what was designed and what actually gets built. That dual credential is still rare in the Scottsdale market. Very few firms in Arizona hold both an interior design credential and an active ROC license, which means most homeowners are still stitching together a designer and a contractor themselves and hoping the two communicate well.

"I built my company out of a genuine love for transforming spaces, starting with my own homes," Lauren told Commercial Construction & Renovation. "Over time I had watched too many homeowners get stuck in the gap between their designer and their contractor." That line is the entire thesis of the design-build argument, and it is worth sitting with if you are currently trying to decide whether to hire one firm or two.

The practical difference shows up the moment a client falls in love with something that has a structural implication. If you are working with a separate designer and contractor, that decision typically waits for the contractor to weigh in later, which can mean days of delay and a client left guessing about cost. Because Lauren holds both credentials, she can assess a structural question on the spot, in the same conversation, and give a client an honest read on what is possible and what it costs before the meeting ends.

Living with Lolo also built its own operating system, called Lolo OS internally, to manage procurement, scheduling, and project visibility in real time across every active job. It is a detail that will not show up in a portfolio photo, but it is one reason a general contractor in Scottsdale that also designs can hold a tighter schedule than a firm juggling handoffs between separate vendors. Clients never have to manage that relationship, because it is internal to one team.

This is also where a design-build firm earns its fee on the harder projects. Every project has a chapter that tests it, and some of the most demanding work Living with Lolo has done has been on older homes with hidden conditions behind the walls. The firm now runs thorough pre-construction assessments on every project and builds contingency into both the schedule and the budget as standard practice, not as an afterthought added after something goes wrong. Clients who go through a difficult chapter with Living with Lolo almost always become the most loyal advocates, because they see firsthand how the team handles pressure instead of just reading about it in a portfolio.

When Commercial Construction & Renovation asked Lauren to name the project that best represents Living with Lolo's approach, she pointed to a full renovation in North Scottsdale the firm calls Lolo Prestige Property. The home is roughly 5,000 square feet, and it was the first project Living with Lolo took from concept through construction entirely as a design-build firm, with every trade managed in-house rather than farmed out to a separate general contractor.

What made the project meaningful was not its size. It was the consistency: every decision, from structural framing to final finish selections, was made with the same level of intention, because one team owned all of it. That project has since been featured editorially in its own right, and it gave Living with Lolo the runway to refine how design and construction integrate on every project since, which is a big part of why the firm can now confidently take on whole-home renovations across Scottsdale at scale.

Sustainability in a luxury renovation is less about checking a box and more about building things that last. Living with Lolo specifies materials for durability and longevity, because the most sustainable renovation is the one a client does not have to redo in ten years. The firm works with low-VOC finishes, energy-efficient systems, and vendors who can speak clearly to their own supply chain, and when a client wants to go deeper on sustainability, that conversation happens early in design rather than being added on at the end.

This matters in Scottsdale specifically, where the climate is hard on finishes and mechanical systems in ways that milder markets do not experience. A renovation built for durability in the desert looks different from one built for a temperate coastal market, and that regional judgment is part of what a local interior designer Scottsdale AZ homeowners already trust can bring to a project that an out-of-state firm cannot.

Living with Lolo's design-build projects typically start at $150,000, and most of the firm's work falls between $300,000 and $1 million or more, concentrated in Scottsdale, Paradise Valley, and the greater Phoenix metro. Clients are generally high-net-worth homeowners, entrepreneurs, and professional athletes who want one point of contact and a team that takes complete ownership of the outcome rather than managing multiple vendors themselves.

In Silverleaf and DC Ranch, where architecture and HOA guidelines are often more particular, the design-build structure means fewer approval delays because the same firm managing design also understands what construction can actually deliver within those rules. In Paradise Valley and Arcadia, where many clients split time between multiple residences, that single point of ownership matters even more, because Living with Lolo can manage a project autonomously while a client travels for weeks at a time.

One of the more candid parts of the Commercial Construction & Renovation interview had nothing to do with construction at all. Lauren told the magazine that clients now increasingly find Living with Lolo through research done on AI tools before they ever land on the website, which has changed how the firm structures its content and thinks about visibility. Living with Lolo has put real work into AI-indexed content and structured data, so that when someone asks ChatGPT, Perplexity, Gemini, or Claude which design-build firm in Scottsdale is worth calling, the firm actually shows up in the answer.

That work was successful enough that Lauren launched a second company, Cited Co, to help other service businesses build the same kind of AI visibility. It is a detail that says something honest about where homeowner research actually happens now: fewer people start with a Google search for a general contractor, and more start by asking an AI assistant a direct question and taking the first few answers seriously.

If you are comparing a separate designer-and-contractor approach against a single design-build firm, the honest answer is that both can produce a beautiful home. The difference shows up when something goes wrong, when a wall opens up and reveals a surprise, or when a client wants to change a finish mid-project and needs to know immediately what that costs. A firm holding both credentials can have that conversation once, in real time, instead of routing it through two separate businesses that may not agree.

Living with Lolo manages both interior design and licensed general contracting under one roof for clients across Scottsdale, Paradise Valley, Arcadia, Silverleaf, DC Ranch, and the greater Phoenix metro, under Arizona ROC license #347577. The firm has been named Phoenix Magazine Best Interior Design three consecutive years, 2024, 2025, and 2026, and Lauren Lerner's work has also appeared in Architectural Digest, House Beautiful, Vogue, Martha Stewart Living, The Wall Street Journal, and GQ. If you are weighing a general contractor against a full design-build team for a renovation in Scottsdale, that track record and the ROC license together are worth asking any firm you are considering to match.
