The earliest map to give details of the roads of Sandymount is that published by John Rocque in 1756. The scale of the map is too small to permit the names of the streets other than the main roads to be given, but the plotting of the lesser streets compares favourably with modern maps. At that time Sandymount was the centre of a brickworks run by Lord Merrion and was known as Brickfield Town.

The map shows Sandymount Green, somewhat larger than it is at present, with the two roads which connect it to the Strand, Newgrove Avenue with its distictive link in the middle and Seafort Avenue with Dromard Avenue branching to the north. The Strand Road is also shown, and Beach Road as far as where Prospect Terrace now stands. The continuation of Beach Road northward towards Irishtown was not built until the present century.

Sandymount Road is not shown, although there must have been a track of some sort connecting Sandymount with Irishtown. A short part of what is now Gilford Road is shown as far as Sandymount Avenue which appears to have been the main means of access to the village. On Taylor's map of 1816 this avenue is named Sandymount Lane.

Very few dwelling houses appear and these are probably only the most important ones. There is one on the west side of the Green and one at the top of Seafort Avenue. The largest structure of all is located at the corner of Seafort Avenue and Beach Road and this is named Conniving House. Its extensive site occupied what is now No. 43 Seafort Avenue and No. 21 Beach Road.

The Conniving House was a well known tavern which is described in "The Life of John Buncle Esq." under the year 1725. This is quoted by Weston St. John Joyce in his "Neighbourhood of Dublin" as follows:

"The Conniving House (as the gentlemen of Trinity called it in my time and long after) was a little public house, kept by Jack Macklean, about a quarter of a mile beyond Ringsend, on the top of the beach, within a few yards of the sea. Here we used to have the finest fish at all times; and in the season, green peas and the most excellent vegetables. The ale here was always extra-ordinary, and everything the best; which with its delightful situation rendered it a delightful place of a summer's evening. Many a delightful evening have I passed in this pretty thatched house with the famous Larry Grogan, who played on the bagpipes extreme well; dear Jack Lattin matchless on the fiddle, and the most agreeable of companions... and many other delightful fellows who went in the days of their youth to the shades of eternity. When I think of them and their evening songs "We will go to Johnny Macklean's to try if his ale be good or not... and that years and informities began to oppress me, what is life?"
