Wendy Larson of Siemon and Larson in Boca Raton, a law firm that is working with developers Dean Carson of South Florida and Sam Roti of Chicago, tells GlobeSt.com that demolition will take place the first part of next year. Construction of the townhouse project, to be called Windsor Court at Boca Raton, will take about a year.

Larson didn't disclose the hard construction or development costs of the project. But area construction industry estimators who have worked on comparable townhome ventures tell GlobeSt.com on condition of anonymity the project will probably be built for about $20 million or at least $200,000 per unit.

Prices for the townhouses, a fast-selling product in Boca Raton, will range from $400,000 to $600,000. Each unit will be about 3,000 sf, and will include a porch and a two-car garage.
