The sign for "house" uses
"flat hands" to show the roof and walls of a house.
The hand shape can be either "B" handshapes or just "flat" hands.
There are a couple
of different ways to do the sign "house."
You might see house signed with the fingers pointed upward. I wouldn't sign it
that way for everyday conversation but
this version could be used for times when you want to embellish your signing a
bit to make it more iconic and lively. For example,
I might use this version if I were
telling a story
to a group of children
about a certain "house."
For everyday use though,
I tend to do the sign house with the fingertips pointing forward instead of up.
HOUSE (recommended version)
House and home are two different signs. You should not use the sign "house" when
you mean home.
