A MODERN RESIDENCE As further illustrating the practical appli cation of the principles of specification writing and cost estimating to actual instances of con struction, we reproduce the working plans, de tailed specifications, and revised estimate of cost of a moderate-sized up-to-date residence recently erected at Babylon, Long Island.
A photograph of the building is shown in the plate opposite page 1, in this volume; and in Figs. 1 to 8 the working drawings are repro duced, some minor dimensions only being omitted.
The house was both designed and built by Mr. E. W. Howell, who furnished the copies of the plans, specifications, and estimate for the purposes of this volume. All were prepared by the same person, the figures of the estimate as here given being revised on the basis of actual cost. The cost of the various items would, of course, vary somewhat for a similar house erected in a different part of the country.
