	In general the structures need temporary support of the first stick (or beam) until the final piece is laid and interlinked to the previous thus locking the structure in place. Whilst it is clear that early humans made many version of the round house, it is not clear how many involved a reciprocal roof, though the structure fits well with the use of round wood timber which is likely to have been commonly used.

A reciprocal roof, reciprocal grid or reciprocal frame is generally considered to be a structure that can be self supporting, or where individual members reciprocate support to neighbouring members through their interlinking.

There are a wide variety of structures that might be considered as reciprocating, in that the individual members interlink and support one another, however they can vary in how much they support one another aswell as in the way they are construction.

spiral reciprocal roof might also be referred to as a Mandala roof, and is entirely self supporting, the details of the name and structure are less clear but indication is it has origins in Japan and China as early as the 12th Centrury.

Examples of simple spiral reciprocal structures can be made using varying numbers of long sticks, above 3, laid in an interlining form, as illustrated below by [https://en.wikipedia.org/wiki/User:PeterEastern Peter Eastern]. In general the structures need temporary support of the first stick (or beam) until the final piece is laid and interlinked to the previous thus locking the structure in place.

Whilst it is clear that early humans made many version of the round house, it is not clear how many involved a reciprocal roof, though the structre fits well with the use of round wood timber which is likely to have been commonly used.

( include lamellas structures, geodesic domes, gridshells and the Zollinger roof.

amella structures will be made up of elements which are twice the length of each grid unit, so that the next member is supported at the midpoint of the previous. This type of structure allows each member to be made up of relatively thin two dimensional linear beams or plates, in more complex structures these might be cut into certain shapes that interlink or slot together creating three dimensional structures or gridshells.
