This respected, busy Guild has over three hundred
members (most of whom employ three to twelve assistants),
some of whom quarry stone, some of whom cut,
dress, and lay stone, some of whom only lay stone, and
some of whom make clay or earthenware vessels or tile
and lay tiles.

Constantly busy on the rooftops of Waterdeep where
tile is slowly replacing thatch (which rots too quickly)
and boards (which too easily catch fire when sealed with
pitch, and too readily leak water inside, and rot, when
not), members of this Guild also build most of the City's
new buildings. The Lords frown on dwelling-places newly
built entirely of timber, and restrict such structures to
one story with a loft. Most City buildings are now multistory,
as Waterdeep has filled in almost all of the available
spare within the walls, and is now expanding upwards.

Stone is cut and hauled from the seacoast crags north
of Waterdeep, and brought by ship from Port Llast and
from Mirabar, where dwarves tunneling for new ores
have found it very rewarding to break up the rubble
they used to toss aside into regular, rectangular blocks
and sell it for 1 cp a block. That becomes 2 cp a block in
Waterdeep, and 4 cp a block when a Guild member
builds a structure. Demolition of an existing structure on
the same site is free if the Guild member is allowed to
keep what he can salvage of the stone. Repairs to, or
building onto, an existing structure is 10 gp per Guild
member per day plus 10 gp expenses (lunches) per day,
plus material costs (3 cp a block; 5 cp for marble, obsidian,
or other “finestone” that requires a smooth polish),
plus 3 gp per day per assistant. Most such crews include
five to eight assistants.
