In 1903, the Tods added a guest cottage just south of the access road to their property. Innis Arden Cottage was built to provide a temporary home for Maria Tod’s widowed sister-in-law, Mrs. Cranston Potter, and her three young daughters. The girls attended the all-girl school, Rosemary Hall, in Rock Ridge for a short time before the family returned to their home in the state of Washington.
The oldest daughter, Bertha Marie, married William E. Boeing, the aviation pioneer and founder of the Boeing Airplane Company. Bertha had fond memories of her time at Innis Arden and aptly applied the name to a section of the Boeing estate that is now one of the 14 designated neighborhoods in the town of Shoreline, WA, on Puget Sound.
From 1906 through 1913, the Tods made the Cottage available as a summer retreat for Anna C. Maxwell and her nursing students from the New York Presbyterian Hospital. Maxwell, often referred to as the “American Florence Nightingale,” performed pioneering work in the development of the nursing profession. The Tods’ support of the hospital, and Maxwell in particular, most probably derives from J. S. Kennedy’s tenure as president of the hospital’s board of directors. Besides donating one million dollars to establish a nursing school at the hospital (now known as the Columbia University School of Nursing), Kennedy also recommended Maxwell to be its first director.
Maxwell was one of the first women to be buried with full military honors at Arlington National Cemetery.
During World War I, the Tods had difficulty obtaining sufficient heating oil for the large Innis Arden manor, so they moved into the Cottage for several years.
After the purchase of the point as a town park, the town repurposed the Cottage for seasonal use, installing changing rooms and beach lockers. In 2005, the town detected high ambient levels of lead and declared the structure unfit. The restoration and preservation of this historic structure became the Greenwich Point Conservancy’s first project. After completion of the project in 2011, the Cottage became the home of the Floren Family Environmental Center, named in honor of CT State Rep. Livvy Floren and her husband, Douglas, who stepped up to close the budget gap of the one-and-a-half million dollar project. The Bruce Museum’s Seaside Center, which had opened in 2006 in the Old Barn, then relocated to the Cottage.
Katharine Cotheal Budd designed the Cottage in the Craftsman/Bungalow style that was newly popular after the turn of the 20th century. Budd was an associate of William Appleton Potter, Maria Tod’s uncle who designed the manor house at Innis Arden. She was also the first female member of the New York chapter of the American Institute of Architects. In 1917, the Young Women’s Christian Association retained Budd to design over 70 “Hostess Houses,” which were constructed to house women visiting male relatives and suitors training at nearby military facilities.
