In the dense back streets of Oakland, now mostly given over to student housing, these elegant double houses stand out. They were built in the late 1880s as Coltart Square, which seems to have been conceived by a Philadelphia developer named Wood. Construction began in 1887, with four doubles (eight houses) on Forbes Avenue and thirteen (twenty-six houses) on Coltart Square, now Coltart Avenue. The ones on Forbes have long since disappeared; eleven of the original thirteen remain on Coltart Avenue.

An item in the Commercial Gazette for March 5, 1888 gives us a thorough description of the houses as they were built.

Seeing the need of good, serviceable and complete houses, thoroughly improved and of latest style of architecture, at reasonable prices and in desirable locations, Mr. Wood, of Philadelphia, Pa., came here and had erected on Forbes street and Coltart square, in the most desirable part of Oakland and one of the very beautiful sections of our city, complete and desirably-arranged brick houses of 11 and 13 rooms, with cement cellar, heater, steel range, open grates all fitted for natural gas, cabinet mantels of choice woods and designs, crystal gas fixtures, electric gas lighting and electric bells, bathrooms, all artistically decorated with fine paper and stained-glass, and compactly built and with abundant closets, showing complete and thorough workmanship, streets and sidewalks well improved and good sewerage, within one square of the cable line [cable cars had just begun to run between the East End and downtown] and on the best drives to and from the city. The lots front Forbes street 23×150 feet and Coltart square, which is 50 feet wide, 35×90 feet. These houses are being sold at a very reasonable price and on very easy payments, and the agents, W. A. Herron & Sons, report that two of these houses have been already sold, one on Forbes street and one on Coltart square. A few will be rented to prospective buyers. Any desiring to purchase a complete house at low figures should call at W. A. Herron & Sons, 80 Fourth avenue, and examine plans and gain full particulars.

The houses have been under separate ownership from the beginning, so they are in varying states of preservation; but several of them retain some fine original details.

It seems that the houses sold quickly, and for a while the Coltart Square community was the haunt of well-to-do upper-middle-class families whose names were often mentioned on the society pages. Not until the second quarter of the twentieth century did the rest of Coltart Avenue become the densely crowded line of rowhouses and small apartment buildings it is today. But this one block still retains an echo of its High Victorian elegance.
