Mission Statement
Spring House Institute's mission is to acquire, restore and complete the Frank Lloyd Wright-designed Spring House; to preserve its original architecture as a single-family dwelling for the benefit of the public as a teaching institute; and to foster the arts, environmental stewardship, intergenerational living and working, and world peace through world law.



Needs Statement
  • an excellent treasurer with financial knowledge and skills to fulfill its mission and help grow this amazing opportunity into all its potential. 
  • a marketing expert to help us plan our capital campaign to raise the matching funds for acquisition and restoration grants from the State of Florida.  
  • an educational wizard who has a broad vision with the experience to help plan future programs for the institute, an incredible opportunity and essential part of our mission. 
Impact Statement
SHI has made great strides in the past year. Spring House is now open on a regular basis, every 2nd Sunday from 2-4 pm. This is a major accomplishment for our grass-roots organization. In addition, the unique property is available by appointment for private, school, camp, and special event tours.  
SHI welcomed New York artist Dene Ross at a fundraiser in spring, 2015. Dene displayed her new 'pulp paintings,' vibrant landscapes created from pigmented 100% cotton pulp made of recycled blue jeans. In February 2015 SHI hosted St. Francis Wildlife rescue service at an event featuring Sandy Beck, who demonstrated live 'Lake Jackson Birds of Prey.' Two special occasions were commemorated at Spring House in 2014: June 8 was Frank Lloyd Wright's 147th birthday, and October 25 was the 60th anniversary of the completion of Spring House.
Thousands of people have visited Spring House during the last few years, including tours, fundraisers, Work Days, and our second party for Friends Of Spring House (FOSH). People have stayed in Tallahassee from Miami, Wisconsin, California and many other states because they heard about Spring House.
SHI, Florida Trail Assoc, and Florida Native Plant Society co-sponsored an Invasive Plant Removal Work Day, which removed approximately one ton of coral ardisia. Beautiful trails have been completed through the woods.
SHI has a well established presence on First Fridays at Railroad Square.  Local musicians such as The New 76ers and Sligo Line have donated their time and talent to support SHI.
SHI reached its 2014 goals of obtaining appraisals and a Building Condition Assessment report. We were very happy to learn that the house is structurally sound, although afflicted with extensive cosmetic damage that is expensive to repair.
Goals for the current year:
  • to solve the serious erosion problem that is causing the spring head banks to crumble and horizontal holes to develop under the house-side of the banks
  • to raise funds and obtain letters of commitment from donors to match at least half of the amount we will request for a State of Florida Acquisition and Restoration Matching Grant; 
  • to continue to promote public use and tours of Spring House with improved communications and more creative outreach
Background Statement

 The only private residence designed by Frank Lloyd Wright and built in Florida was constructed for the family of Clifton and George Lewis II on a beautiful 10-acre parcel in northern Tallahassee. It became known as Spring House, for a natural spring and the small stream that flows from the property into Lake Jackson about one-quarter of a mile away. Lake Jackson is an Outstanding Florida Water and a state Aquatic Preserve. 

In 1996, after George died, Clifton Lewis and others formed Spring House Institute, Inc., a non-profit and now 501(c)3, tax-exempt organization of dedicated professionals and volunteers charged with the task of preserving this historic property for the people of Florida and bringing it into beneficial public use. During that first year, SHI collaborated with the Florida State University College of Motion Picture Arts in making a film about Mrs. Lewis while she was living in the home. The film includes a tour of the home and grounds conducted by Kevin Schweizer, whose father Nils Schweizer was FLW’s liaison during the building of Spring House.  

A leader in the “Prairie School” of design, Mr. Wright called his philosophy of building in harmony with nature “organic architecture.” He designed over 1,000 structures, of which less than half were built. In 1991 Mr. Wright was recognized in an AIA survey as “the greatest American architect of all time.” The unconventional passive solar "hemicycle" design of Spring House represents the last stylistic phase of Mr. Wright’s career. Finished in 1954, five years before Mr. Wright died, Spring House is a contemporary of his cylindrical Guggenheim Museum in New York City,one of the 20th century’s most important architectural landmarks.

Spring House Institute hopes to restore this unique architectural gem and transform it into a thriving educational institution and living museum, a center for intergenerational learning and working, focusing on art, social justice, world peace, and environmental stewardship.

Areas Served
Spring House is located in Leon County, as are the headquarters and business activities of Spring House Institute. The vast majority of events sponsored by or related to SHI and its mission have taken place and will take place in Leon County. However, the life and work of Frank Lloyd Wright continue to fascinate and inspire people from all over the world. Interest in and support for the work of SHI is not geographically limited.
Board Chair Statement
I grew up in Spring House. Mr. Wright designed this amazing home for my parents Clifton and George Lewis II, my three brothers, George Edward Lewis II, William Van Brunt Lewis, Benjamin Bridges Lewis, and myself, Clifton Byrd Lewis Mashburn.
People ask me what was it like to live in Spring House.  Please come for a visit, sit by the fireplace downstairs and stay a while.  You'll be able to feel the house, enjoy the amazing space inside, hear the birds, see the woods, and become part of it yourself.  Walk the trail down by the pond and back to Spring House, enjoy the quiet, fresh air, the trees.
SHI has accepted the challenge of introducing Spring House to the greater community, helping people become aware of what it is, of its importance, and what it can become to Tallahassee and the greater community.  We are an educational institute, and the first part of our program is what we have been doing since becoming active in the community, sharing Frank Lloyd Wright 's role in world history, and Spring House's place in his legacy.  Our parents, who asked Mr. Wright to design this home for us, in Florida and what they contributed to this community during the struggle for civil rights in Tallahassee and the country, and their other contributions in the arts, environmental protection and world peace, are all part of Spring House history.
Thank you to the many many people who have shown their commitment to helping us make this happen, by your donations, your hard work, and sharing our story and website.  If we succeed in our mission, it will be in large part to your helping us!
CEO Statement/Executive Director Statement

 While attending the 1950 World Federalist Conference at Florida Southern College in Lakeland, FL, George and Clifton Lewis asked architect Frank Lloyd Wright to design a home for them, saying they “have a lot of children and not much money”.  Clifton believed Mr. Wright could design a house with a soul.  Wright agreed, instructing them to “Go find your ground, not on a lot.” After one year, they located a beautiful 5-acre parcel in Leon County on the outskirts of Tallahassee with a natural spring that often flows from the property to Lake Jackson. Mr. Wright completed the plans in 1952: an unconventional passive solar “hemicycle” design, which made it difficult to find a builder. In 1954, Nils Schweizer, Mr. Wright’s southeastern representative, was sent by Mr. Wright to find a qualified contractor. Ernest Daffin, a local architect and family friend who worked for Jack Culpepper Contractor, helped recruit Mr. Culpepper to undertake the project, as Clifton recalls, “to build a livable house for an agreed-on price...” Local building codes and site conditions required modifications, including a much larger foundation than originally planned. Due to additional costs, some of the exterior features of Mr. Wright’s design were not completed, among them a terrace wall and reflecting pool.

By December 1954, construction had ended and the Lewis family moved into their new home. Frank Lloyd Wright died in 1959 never having visited the property.

Mr. Wright and the Lewis family shared the dream of a peaceful world governed by people of all nations who solve problems without war and foster the creative spirit. Spring House Institute is inspired by this vision. “World Peace through World Law” would be one of many classes taught at the Institute. The captivating space would be used for seminars, workshops, meetings, retreats, performances, gardening, nature study, and other similar purposes. Restored and completed, Spring House would be a natural tourist attraction and a boon to the economy of North Florida.

Long term Success Ultimately this program will result in a fully restored/reconstructed Spring House, available for public use and enjoyment. It will be a destination attraction for scholars, artists and art lovers, Frank Lloyd Wright fans, brides, new grads, and interested people from around the world.
Program Success Monitored By Program success is monitored by the SHI board of directors, who meet periodically to devise the next step in stabilization and restoration, and report on the results of previous steps.
Examples of Program Success Past successful projects of the stabilization/restoration program include removing tall glass doors that had become unsafe; fabricating a temporary wooden construction door to secure the premises; tree removal to halt damage by large roots; grading the earthen area surrounding the house to improve drainage; and spreading a mulch surface to keep down the mud. an Eagle Scout has expressed an interest in doing an environmental project at Spring House grounds with his troop. A major goal is to restore the spring for which Spring House is named. It has been damaged by development and ill-advised regional water management practices. The roof has been fixed.  Necessary plumbing has been made functional. Electrical service has been improved. Fuel oil furnace has been repaired.

Short Term Success
In 2012 and especially 2013, SHI has increased activity at Spring House. Photos of Spring House were included in the LeMoyne "Art in Architecture" show in August, 2012. Our website went live in December, and in May 2013 we had 2500 unique visitors.
In January, 2013, SHI sponsored a Workday and Celebration that attracted almost 150 volunteers, to weed, rake, prune, shovel, dig, grade, dust, mop, wash and generally spruce up the house and grounds, in final preparation to greet a wider public at Spring House. SHI conducted Fireside Chats in February and March, 2013, to discuss with community members the art and architecture of FLW, and the mission of SHI. We started "Friends of Spring House" as another way for interested people to support us and be recognized.
The FSU Art Department arranged for several classes to meet at Spring House during the spring session. Students completed assignments using the architecture and environment of Spring House for inspiration.
On April 5 Robert Olen Butler and Erin Belieu read from their work at Spring House. SHI staffed a table at the LeMoyne Chain of Parks Art Festival over the April 20th weekend. A successful fundraising party was held at Spring House on April 27, 2013. The family of a recent FSU graduate chose Spring House as the venue for her graduation party. Periodic tours are forming now. 
Long term Success Ultimately Spring House will be a completely restored Frank Lloyd Wright jewel, open on a regular basis, as a house museum and a destination for lovers of history, art, and architecture, from around the world. Currently Spring House is the venue for public and private events, such as workshops, seminars, parties, art shows, among others. These uses will increase as SHI gets more support.
Program Success Monitored By Success will be monitored by community participation; funds raised; and number of hours that Spring House is open and in use.
Examples of Program Success As a result of the Work Day/Celebration; the art classes; the April 5 reading; the April 27 sunset party; the graduation party; and individually arranged tours, over 500 people have visited Spring House in the last six months. We now have more money in our bank account than we have ever had before, and all bills are paid!
Program Comments
CEO Statement/Executive Director/Board Comments

The importance of saving Spring House has been recognized by the National Trust for Historic Preservation, which listed Spring House as one of America's 11 Most Endangered Historical Places for 2014. The Florida Trust for Historic Preservation put Spring House on its 2012 and 2015 lists of the 11 Most Endangered Historical Places in Florida, as a significant historical site threatened by “nature and development pressure.” SHI needs to raise the money to buy Spring House in order to keep it open for public use and enjoyment. The open market will attract buyers who plan to enjoy the serene, beautiful site in private.

Saving Spring House is a finite opportunity. It won't last forever. It began when the Lewises, having felt, and seen what Spring House meant to their family, friends and other visitors, dreamed of sharing this experience in a much broader way. Clifton Lewis started Spring House Institute as a way to restore Spring House for good public uses so many people can enjoy the soul of the home. The house has to be restored for this dream to be realized, and it can't wait forever. SHI is doing a great job, and we need some large donors who can see the importance of Spring House, what it is, and can be, and want to be part of the solution to save the house for all people. It is a treasure that must not be lost.

CEO Comments

Clifton Van Brunt Lewis founded Spring House Institute and the visionary who developed its mission. Her passion for the idea of a 'house with a soul' led her to Frank Lloyd Wright and to construction of the jewel in the woods we know as Spring House. Clifton was a great lady, her mind was sharp and sharing. Unfortunately, her failing sight and hearing made it impossible for her to be actively involved in board meetings. Therefore, before her death in 2014, she was elevated to President Emeritus and her daughter Byrd Lewis Mashburn was elected by the board to lead SHI.

Byrd Lewis Mashburn grew up at Spring House, with her parents, Clifton Van Brunt Lewis and George Lewis II, and her three brothers. She lived there from 1954 until she left home at 21 after attending FSU.  She returned to Spring House in 1994 to help her parents, and lived there with her mother until 2006.  Byrd continued to live with Clifton in Tallahassee until Clifton's death in February 2014, but not at Spring House, which is now devoted to the mission of Spring House Institute.

Byrd received her Bachelor of Science in Management Information Systems from University of South Florida in 1990. She graduated with honors as a member of Golden Key National Honor Society, Beta Gamma Sigma International Business Honor Society, and was included in the Outstanding College Students of America for 1990.

To care for her family and to keep Clifton’s vision of SHI alive, Byrd carried three part-time jobs, working seven days a week until her job at the Tallahassee Democrat became full time in 1998.  She continued to work on weekends, selling health food products at the Honey Tree until the end of 2006. In 2001, she took a position with the Florida Department of Agriculture and Consumer Services as a publication production specialist in the Division of Marketing, graphics section. Until she retired in 2013, she was in charge of the image center and the graphic jobs database.

Byrd’s determination, competence, dedication, knowledge, understanding, work ethic, leadership, and all around good sense inspire others to help make the SHI mission come true.

Organization Comments

In its first 15 years, SHI raised just enough money to maintain a legal corporate existence. By end of 2010 none of the Lewis family were living at Spring House, so SHI  begun planning for its use and occupancy of this architectural and historic treasure. The first serious fundraising efforts were targeted at stabilizing the house (replacing unusable oversize glass doors with a wooden construction door; installing interior support columns), and clearing the grounds (removing a large oak that was damaging the wash house; clearing a path around the house) Since the 1st Work Day and Celebration in January 2013, SHI has held at least eight special fundraising events targeting local community leadership, universities, and the arts community. In addition, SHI opens Spring House for tours every 2nd Sunday from 2-4 pm. 

More fundraising events and projects are in the planning stages. Tours are available on request. People are becoming Friends of Spring House, buying T-shirts and other items, donating, pledging. But we need some major grants or donations. Our wish list, aside from a major grant and matching donations to purchase Spring House,  is $5000 for a construction fence.

SHI needs to pay an architect and engineer to design solutions to identified problems, and engage a contractor to undertake the repairs. Expert artists, builders, and preservationists will guide and mentor SHI’s many friends and volunteers in working on the project. SHI supporters in the local community and far afield are poised and eager to begin the restoration process so that the visions of Clifton and George Lewis and Frank Lloyd Wright can be realized.
