About Ballard + Mensua

Founded in 2005, Ballard + Mensua is a full service architecture firm with a specialty in truly unique and custom homes and renovations. We help our clients with projects of all sizes, whether helping a young family with a master plan to build in phases as they can afford, or designing dream homes to retire to on the water or in the mountains. Our unique cost study process helps to offer the advantages of design build, with the checks and balances of independent architect and builder. While many architects do not understand construction well, or interiors well, we believe in a fully integrated project management approach and specialize in interior design and construction management. Our drawings are both client friendly, and contractor friendly. We detail drawings in a way that tells the contractors exactly what to build and our details work because we have built before. We value our contractor and vendor relationships as much as our client relationships. After Seth Ballard's 21 years of practice, these relationships allow us to build virtually anything, no matter how custom. We have a further specialty in historic preservation. Ballard Mensua however, loves working in every style... we find it more fun to work on a contemporary, a Georgian, a colonial and an arts and crafts house all at the same time.

Who do we want as our client?

This website sometimes scares away potential clients with smaller projects. You might think that we want only large projects ... you might think as an architect, we would not want to design a deck or a bathroom or a built-in bookshelf.

The fact is that no project is too small.... as long as you really understand the benefit that we are bringing to the table as your Architect.

We want clients who want our help .. want our creativity .. want our experience.

An Architect – is a Custom Tailor

The Architect, when working with a Client, must first measure the Client – learn about the Client’s wishes, needs, goals …. How does the Client’s family live now? How will they grow? What works, what doesn’t?

What is the style of the furniture and art a client has now? Or desires to have as they can afford it?

As we measure a house, or as we learn about any Client’s program needs, it is equivalent to taking a Client’s measurements.

What is the soul of the site? Where are the best and worst views of and from the house? What is the wind direction? What is the sun orientation? Where are trees?

What is the budget?

Only once an Architect understands a Client's true needs, can the Architect design a project that suits them.

This takes the involvement of the Client:
The best projects we’ve been involved in have been a result of a very involved Client – one who brought forth their own ideas, images from magazines … studied plans and made suggestions, questioned details and gave feedback throughout the process.

Ballard+Mensua wants Clients who are involved – this will naturally result in a portfolio that will show a variety of styles – from colonial, to arts and crafts, to contemporary, to cottage style.

This takes humility on the part of the Architect:
One of the greatest lessons Seth Ballard learned from his mentor, Douglas Soe Lin, is to “be humble and carry a big stick.” Translation: be humble, but not shy.
An ego, on the part of an architect, tends to block off the ability to listen to a Client’s reaction or input.

The Architect must think outside the box:

Ballard+Mensua Architecture LogoAll of a Client's needs, overlaying with site restrictions, technical concerns such as tying in plumbing lines, or how to heat and cool a space …. are often conflicting. Often budgets are restricting as well. The compounding of all of these variables can box in a thought process to limit results.

But with trained problem solving approach, what can seem limiting to some, often in architecture becomes the best feature of a project – a required beam leads to a ceiling cove, required drainage leads to a bridge... by thinking outside the box, the negative becomes the positive.

The Ballard+Mensua logo is intended to show our philosophy of thinking outside the box, of understanding that every problem has its balanced solution.

Feng Shui / Earth Spirit

As part of Seth Ballard's college thesis, he researched parallels in the design philosophies of several ancient cultures -- India, China, Japan, Celtic cultures and Native American.

All of these cultures shared a guiding set of design principles, which have a great deal to do with the earth's natural forces.

Some are practical and just involve common sense -- such as if there is a valley and the valley slopes downwards, beware of placing a building there (it will be subject to winds and flood).

Some are less obvious and relate to our own projection of energy or chi --- as we move in a direction, we project ourselves. If a building is easy to move through, without obstructions for the eye or our bodies, we receive no negative impulses or energy, and are more naturally happy.

Since he was a small child, Seth Ballard was innately sensitive to these forces in the physical environment. He sought to work for an Asian Architect who was very tuned to these forces...and he brings a tremendous respect and understanding of their importance to all of our designs at Ballard+Mensua. He further honed these instincts through intensive study, while at Tulane, and practiced under a master of feng shui.

Extensive travel, study, and work experience in Asia, Europe, and here at home have contributed to our vast respect for natural laws of design. Regardless of the style of a project, size, budget or level of finish, good chi is a foundation that is inherent in all of our work at Ballard+Mensua.

1996 – 2005 – Project Manager – Soe Lin and Associates Architects – Bethesda, MD
Under the direct mentorship of internationally acclaimed architect, Douglas Soe Lin, Seth Ballard learned the practice of architecture from the ground up. Mr. Soe Lin is a 6th degree black belt in Bando, a Burmese martial arts form and taught Seth architecture in a similar manner to that of a martial arts master. Seth jokes he was the Karate Kid architect – he would ask Mr. Soe Lin a question about a project, and Mr. Soe Lin would answer “draw a section.” Seth would draw the section and find the answer.

Mr. Soe Lin set a very high standard for all that worked under him and taught Seth the foundation of his practice – treat every house as if it is your own, treat every project as if it was your money on the line. Service and unbending dedication to the client – to see the project through design and successful completion of construction.

At SLA, Seth Ballard handled ½ of SLA’s workload, including 40 – 50 residential projects per year, commercial interior fit-out projects, historical renovation projects and assistance on developments in southeast Asia, including the first General Hospital in Rangoon, Burma. On his own and while at SLA, Seth has handled over 250 projects of various types, and overseen over $400 million worth of construction.

To see some residential examples of some of these projects Seth completed while at SLA, click on portfolio and "projects prior to 2005."

In early 2005, Seth Ballard decided to branch out on his own. He established Ballard+Mensua, LLC with the goal of providing tailored residential design and construction management services to a small group of select clients. Since then, we have completed several dozen projects with budgets ranging from $50,000 to $5 million -- that you can see demonstrated under the portfolio section of this website.

Seth is a licensed Architect and member of the American Institute of Architects.

Though not right for all projects, Seth hopes to find ways to incorporate green building technologies into all projects, with the goal of saving clients money through minimizing waste of materials, while also reducing the impact on the environment.

  • The Bullis School Graduate, 1968
  • US Navy Aviation Machinist-- Squadron VC10 (Guantanamo Bay, Cuba) 1969-70, VF32 (Norfolk) 1971-72, VP68 (Pax River, MD) 1973-1975
  • MBA, Urban Studies, University of Maryland 1976
  • Commercial Sales Engineer, Robertshaw Controls Company, 1977-78
  • Owner, Mechanical Systems Maintenance, Inc. 1980 – 1985
  • Owner, Bell Builders Inc. 1985 – 2011
  • Consultant, Construction Manager 2011 - 2016

Frank Bell and Seth Ballard were introduced by Joe and Diann Martin in early 2016 when the Martins were interviewing Seth Ballard to become the architect for the restoration of their family Dairy Farm property, Potomac Riverside Farms in Hedgesville, West Virginia. The Martin’s invited both Seth and Frank out to the property to inspect the 1815 farmhouse and surrounding outbuildings, which had been left in disrepair, and were reclaimed by the Martin’s when the newer owner went into foreclosure. As Frank and Seth toured the building and gave advice about what to do throughout the day, Frank or Seth would comment on advice of what to do, and consistently it was the same advice. Later the Martin’s asked Seth if they should have Frank Bell assist to manage construction and Seth said clearly “Definitely!” They asked Frank if they should hire Seth as the architect and Frank said “Definitely!” As Seth learned more about Frank, he realized what an amazing asset Frank Bell is for any construction project, both as a designer and as a construction manager. The two have now worked together on the Martin project through design and construction for two years and have now made their relationship more formal. After years of semi-retirement, taking on only some part time consulting to help prior clients, Seth has lured Frank back into the “game” with a slightly different role. Frank will continue to be heavily involved in the design of projects, will help Ballard Mensua to produce even better drawings by reviewing them with the keen eye of a very experienced builder and will help to oversee and inspect projects while under construction. Ballard Mensua now gives Frank a team of Architects to back him up in the design of his projects and the development of highly detailed drawings. As you can read more below, Frank’s company Bell Builders really set the standard for a quality home and Ballard Mensua is really proud and honored to have him on board.

More info about Frank’s History: Frank Bell is a native of Montgomery County, MD where he has spent most of his life and career as a Builder. As former President and Owner of Bell Builders, Inc. headquartered in Bethesda, MD, Frank is recognized throughout the Washington Metropolitan Area for creating homes of unmatched quality and beauty. creativity, and passion he puts into the beautiful custom homes and projects that he and his company produce. Frank has been frequently highlighted in the Washington Post, and other local media outlets for his work in improving the aesthetic of Montgomery County’s neighborhoods and communities one home at a time; an effort that has also earned him numerous awards from several distinguished national and local trade organizations for over 30 years. This includes projects recognized by the Maryland Building Industry Association (formerly the MNCBIA) for excellence in residential home building, including multiple Gold Awards for annual Best Custom Homes; Custom Additions; and Whole House Renovation projects. Frank began his career as a Flight Crew Member and Machinist in the US Navy, and upon discharge went on to earn a bachelor’s degree in Urban Planning from the University of Maryland. After graduating from UofM, Frank entered the commercial mechanical construction industry, where he eventually owned and operated his own company. After the profitable sale of this company in the early 1980’s, Frank’s professional focus turned to residential construction, a family tradition led by Frank’s father, Meade Bell, who was a prominent Home Builder in the Washington DC area since the 1940’s. Joining in his father’s legacy of fine home building, Frank established Bell Builders, Inc. in 1985. Throughout his building career Frank has worked to ensure that each of his signature homes not only improves the lives of the homeowners, but that each becomes a recognizable and respected landmark within that neighborhood and community. In this way, Frank is able to make small yet tangible improvements to the communities where he has worked and lived throughout his life, a responsibility Frank feels fortunate to have. With an eye for exquisite detail and the experience of a master, Frank Bell proves that quality construction still exists; that refined elegance is attainable; and that excellent honest work will never go out of style.
