The modern houses of New Canaan
New Canaan, Connecticut has more than 100 mid-century modern houses built from the late 1940s through the 1970s by the Harvard Five and other architects. About 20 have been demolished; protection varies by house and rests mainly on preservation easements and a town demolition delay of up to 90 days, since National Register listing alone doesn’t restrict private owners. Philip Johnson’s 1949 Glass House, a National Historic Landmark and National Trust Historic Site, is open for guided tours.

What makes them distinctive
- The Harvard FiveMarcel Breuer, Landis Gores, John Johansen, Eliot Noyes and Philip Johnson settled in New Canaan in the 1940s and experimented with modern houses.
- Fast startMore than 30 modern houses had been built in town by the end of 1952, and more than 100 by the end of the 1970s.
- Beyond the fiveVictor Christ-Janer, John Black Lee, Willis Mills, Hugh Smallen, James Evans and Gates and Ford also designed modern houses here, and Frank Lloyd Wright and Edward Durell Stone each designed one.
- The Glass HouseJohnson’s 49-acre site holds 14 structures built from 1949 to 1995 and was designated a National Historic Landmark in 1997.
- First historic districtSix houses on Chichester Road, built 1956–1964 on a 1955 subdivision whose sales contracts required modern designs, became the town’s first National Register historic district in 2026.
- LossesEliot Noyes’s first house, from 1947, has been demolished, and a 2005 report said three of John Johansen’s seven New Canaan houses were gone.

Designation and the rules
- Demolition delayAfter a written objection, the town may impose a wait of up to 90 days before issuing a demolition permit for a building over 50 years old and over 500 square feet. A 2016 state law lets towns use up to 180 days; we couldn’t confirm that New Canaan adopted it.
- National RegisterListing alone places no restrictions on a private owner, so a listed house can still be altered or demolished. Individual houses were listed in 2010 under a statewide submission for modern residences, and Chichester Road followed as a district in 2026.
- Preservation easementsEasements signed in 2019 on Landis Gores’s house (held by the National Trust) and Eliot Noyes’s 1954 house (held by the Connecticut Trust) bind future owners and require approval for alterations; the Gores easement also bars demolition and subdivision.
- State tax creditConnecticut’s Historic Homes Rehabilitation Tax Credit covers 30% of qualified costs, up to $30,000 per unit, for owner-occupied homes of one to four units on the National or State Register, with at least $15,000 spent and five years of owner occupancy afterward.
before you buy
What to check before you buy
- Search for easementsA title search shows whether a recorded easement applies; easements like those on the Gores and Noyes houses require the holder’s approval for alterations.
- Roofs and glassThe original architects struggled with leaking flat roofs, and walls of glass are a defining feature, so have roofing, drainage and glazing inspected by a specialist.
- Radiant heatSome houses have radiant heat under stone floors; ask for the system’s age and service records.
- Teardown pressureSmall original footprints have driven demolitions, such as a 1,700-square-foot, two-bedroom 1953 Philip Johnson house whose 90-day delay expired in 2008.
- Zoning and district rulesThe Planning & Zoning Commission began rewriting its regulations, last fully updated in 2007, and a 1963 local historic district in the old village core reviews changes there, so confirm current rules before planning an addition.
Sources disagree on counts and dates: more than 100 modern houses from 1946–1980, 1949–1973 or 1948–1976 depending on the source, 91 identified by the 2008 survey, and about 20 demolished in a 2026 report against about a dozen of 75 in 2005.

questions
Questions we hear
How many modern houses were built in New Canaan?

Does National Register listing stop a teardown?
No. Listing alone places no restrictions on a private owner; a recorded preservation easement or the town’s demolition delay of up to 90 days does more.
