Design-Build vs. General Contractor: Choosing the Right Partner for a Nashville Renovation

January 7, 2026

In This Guide

The core difference between design-build and general contracting • Who’s on your team • How pricing and timelines compare • Why it matters at the whole-home scale • Questions to ask before you hire

If you are planning a significant renovation in central Nashville, one of the first decisions you will make is not about finishes or floor plans. It is about how your project will be run. Design-build and traditional general contracting are two different ways to get from an idea to a finished home, and they lead to very different experiences.

Here is a direct answer to the question homeowners ask us most: a design-build contractor manages design and construction under one team and one contract, while a traditional general contractor typically begins work only after a separate architect has already finished the design. That single difference shapes everything from your budget certainty to your timeline.

One team. One contract. One vision from start to finish.

How the Two Models Actually Work

Traditional General Contracting

You hire an architect to design your renovation, then take those finished drawings to one or more general contractors for bids. The contractor was not part of shaping the design, so budget surprises often surface only after bidding, when real construction costs meet a plan that was never priced along the way.

Design-Build

Architecture, interior design, and construction sit under one roof from the first meeting. Budget is part of the conversation from day one, so the design that gets finalized is a design you can actually afford to build, with a fixed-price proposal before construction starts.


Why This Matters More at the Whole-Home Level

A $1M–$2M whole-home renovation touches dozens of interdependent decisions: structural changes, systems upgrades, cabinetry, and finishes that all need to work together. Coordinating that across separate architecture and construction firms adds risk, delay, and finger-pointing when issues arise. A single design-build team removes the handoff entirely.

  • One point of contact for the entire project, from first sketch to final walkthrough
  • Budget pricing informs design decisions in real time, not after the fact
  • Faster overall timeline, since design and pre-construction planning overlap
  • A single fixed-price proposal instead of competing, hard-to-compare bids

See how this plays out on a full project in our Our Process overview.


Cost and Timeline Comparison

  • Design-build whole-home project: design and pricing typically finalized in 8–14 weeks, with construction following immediately
  • Traditional model: architecture phase alone can run 3–6 months before bidding even begins
  • Design-build budget certainty: fixed-price proposal before construction starts
  • Traditional model budget risk: final construction bids often land 15–30% above early architectural estimates

Common Questions

Is design-build more expensive than hiring an architect and contractor separately?
Not typically. Because budget is part of the design process from the start, design-build usually avoids the costly redesigns and change orders that come from a plan priced too late.

Do we lose creative control with design-build?
No. You still work directly with an in-house architect and interior designer. The difference is that construction realities are part of every design conversation, not a surprise afterward.

Is design-build a good fit for a historic home?
Yes, and often a better fit. One team can weigh preservation goals, permitting requirements, and construction methods together instead of in separate silos.

What should we ask a contractor before hiring them?
Ask for a defined, fixed-price proposal, examples of comparable whole-home projects, and a clear single point of contact for the life of the project.


Where to Start

The best way to compare models is to sit down and talk through your goals directly. We will walk you through how a design-build partnership would handle your specific project, budget, and timeline.

Enriching lives through exceptional remodels

They are reliable, wonderful crew and very friendly. I would recommend them any day. They always put customers first, before anything else.

John

Hilson and his team are professional and timely (something not common in this industry!). Went above and beyond to make sure everything was up to our standards/liking. Would definitely recommend him to anyone needing something built/remodeled at their home.

Bryan

Merrill Construction Group completed my major kitchen renovation, and I was very pleased. A few things that I really appreciated: #1 – Hilson and his team are great at communicating on a daily basis about the project; #2 – Hilson and his team are very nice and trust-worthy guys; #3 – I was pleased that the project wasn’t delayed or come in over the quote.

Camellia

Merrill Construction Company remodeled two bathrooms in our 1920s house as well as a laundry room. We were more than satisfied with every aspect of the project from the design consultation at the beginning to the outstanding workmanship of the tile layers, painters, plumbers and electricians. The project was even finished on time and under budget.

George

Merrill Construction Group had done a fireplace and a kitchen redo for my neighbor, who was very happy with the job. I felt Mr. Merrill was neat and professional, always took and returned my calls on time and had some good ideas for my fireplace so I accepted his bid to perform the job. I liked the fact that everything was written down and that the supervisor, Thomas, was intelligent and professional. They did a marvelous job. It is beautiful and took less than a week start to finish. Everything was left neat and clean, and Merrill Construction Group even lowered the amount they originally thought it would cost because it took less time than they had thought it would.

Jeanne

I have worked with Merrill Construction Group for a number of years. They have completed renovations large and small in our house, including a full bathroom remodel (see most recent floor install in picture), an update to our kitchen and even exterior house painting and repair. Hilson Merrill is always professional and courteous throughout the job. I trust him, his crew and project managers to keep me updated on the project and let me know when problems arise – which is inevitable with a historic 100-year-old home! They stay on budget and are transparent throughout the process. I highly recommend the company and will use them again!

Sara

Merrill Construction Group was of the highest quality for my home renovation. The workmanship was excellent. The crew was helpful and the contractor was available when needed and had great ideas or solutions to questions I had. I have hired them more than once and would readily do so again.

Pam

Hilson Merrill is very professional & his quality of work is a reflection of his high standards. He and Thomas are friendly and easily accessible to set appointments to complete projects.

Kristal

Hilson’s crew is extremely professional and great to work with. We used them for two projects within the last 18 months and both times they delivered on time and under budget. I would highly recommend him for your next home project.

Drew

They walked in to an unfinished problem, and took it to completion quickly, on budget, and at a very high quality.

Julia

Last year Merrill Construction Group remodeled a master bath, a studio and enclosed a hot patio for us. We are enjoying these improvements to our home so much! They did an excellent job. The sub-contractors were very fine workers with above average skills. They were on the job and we were finished very close to the time that was allotted for the work. Love this company and highly recommend!

Anne

We hired Hilson Merrill to help us add a screened porch to the back of our home as well as add a new roof on our home and porch. The project was completed on time and within budget. Our porch is by far our favorite “room” in our home. It was beautifully designed with the help of a draftsman that Hilson recommended. Hilson was responsive to all of my emails, questions, and requests throughout the project. He is honest and upfront about the building process. We would highly recommend this company!

Laura

Great Job! Very professional and great communication. Everything happened on schedule and in budget. I highly recommend Merrill Construction Group. Thanks, Hilson!

Dillon

Our remodeling experience with Merrill Construction Group was fantastic. Mr. Merrill gave us an estimated cost and gave us a plan for both the builder and homeowner to move step by step through the process. It was always very professional. We never wondered what we needed to do next or when work would be finished. Deadlines were set and met. Every question along the way was answered very quickly. The quality of the work exceeded our expectations. If we had an idea, we worked together for the most positive outcome. His subcontractors and staff were terrific!

Lucianne

We did a master suite addition, with a screened-in porch and two covered porches. Merrill Construction Group did an excellent job on the addition and we were especially impressed with how they made the addition fit into our existing home. You cannot even tell that there is a new part. We love our renovation and thought they did a fantastic job.

Stephanie

Originally remodeled two bathrooms and did a great job. Recently remodeled our downstairs including the kitchen. They started exactly when they said they would. They finished on time and on budget. They were respectful and kept our needs in mind. I would always use them for projects in the future.

Janis

We hired Merrill Construction Group for a total master bath and closet renovation. Hilson and his team are very professional and were quick to respond to all our questions and requests. His crew kept the site clean, showed up when they said they would and did excellent work. We highly recommend Merrill Construction Group and look forward to working with them again on future projects

Kim

I can’t say enough good things about our renovation process with Merrill Construction Group. The team is comprised of the best of the best. The attention to detail and project management throughout our seven-month project exceeded all expectations. We’re thrilled with how everything turned out and would recommend them to anyone.
