Part of this year’s experiments has been to design a modular Sofa Unit – pretty much so that you can add pieces, as you can afford them. You can start with 2 Armchairs, then add a middle piece to turn the set into a 3 seater. Add an ottoman, and you have an L shaped Sofa.
** an added benefit to this, is being able to fit it into apartments. My experience has taught me to make furniture that can fit througth apartment doors. Strange but True.
