226 On Concrete as a Buildinfj Material fur 



In each design the roofs are supposed to be covered with 

 Broselej tiles, having plain or ornamental ridge-cresting, and all 

 brickwork jointed with black mortar. 



These lew hints will show that the honest face of concrete 

 can be made to look quite as ornamental as either brickwork or 

 stone ; and I hope they will be the means of restricting the 

 general custom of coating or facing with cement, which prevents 

 the passer-by from judging of what material the building is 

 erected, until time and weather has caused some of it to crack 

 and fall off. 



The following specification and estimate of the several works 

 are intended to show what the probable cost of the Cardiff pair 

 of cottages* erected in concrete would be, but with a slated 

 instead of a tiled roof; the porches and dormer windows being 

 omitted on the score of economy.
