Merfolk cities are often very densely constructed compared to land based races for a number of reasons. Roads can be very narrow by terrestrial standards because merfolk are able to use three dimensions for their streets. Sometimes the upper floors of buildings are conjoined across the streets which turns the streets into tunnels. Some cities have been built up over time so that tunnels have completely replaced streets in many areas.

Merfolk are able to construct buildings much more efficiently than land races. They attach inflatable gas bags to a large building materials and lift them by filling the bag with air. Only a few workers are needed to position the piece. For this reason, gigantic buildings and monuments are common in merfolk cities.

Merfolk structures often incorporate unique materials and features which results in distinct a architectural style. Wooden buildings are uncommon due to the effect of woodworms. Instead, Merfolk make use of a variety of durable marine building materials:
*'''Kelp''' - Many merfolk buildings are made by weaving living kelp into a hollow ball that floats in the water while anchored to ocean floor. There can be several rooms arrayed in a daisy chain, one above the other, all constructed from only a few plants.
*'''Sea Grass''' - Sea grass is used as a filler material in thatching and living sea grass is planted on the roofs of buildings as an anchor or decoration.
*'''Coral''' - Coral is tough easily workable, and abundant in tropical climates. It is used all over the aquatic world.
*'''Stone''' - Used in alone or in combination with hydraulic cement, stone is one of the best materials for durability. 
*'''Hydraulic Cement''' - Hydraulic cement is a building material in use since ancient times and is known for its ability to harden underwater. Hydraulic cement is combined with sand or other materials to create concrete structures, or is used in mortar to create masonry buildings
*'''Giant bones''' - The bones of giant sea creatures such as whales and sea serpents are and strong and durable enough to be excellent building materials
*'''Giant Shells''' - Some sea shell are large enough to be used by themselves as rooms in buildings. Smaller ones are used in "shell masonry".
*'''Wood''' - Freshwater merfolk often use wood to build their structures, because woodworms do not live in freshwater.
