A Rumford design is very shallow, has outward-flaring sides, a back that arches forward, a curve on the underside of the front lintel leading back to a broad slot-like flue with a flue chamber above it. The overall front opening is almost square, sometimes slightly taller than wide. Rumford fireplaces are very distinctive looking. You can get some basic information from this wikipedia article here: https://en.wikipedia.org/wiki/Rumford_fireplace and there is plenty of info online, even ready-made reproductions (more or less accurate). Rumford developed his improvements and published them in the late 1790s, just before fireplace heating was displaced by stove heating (a process already well underway when Rumford developed his improvements). Good luck with your whatever you decide to do.

where do u stay... if ur really interested in changing ur kitchen in a spacious manner.. pls consult us for the same.. i will make more use of space with necessary electronics gadgets to be placed along with other necessary food items... Because whatever is the square feet we get in kitchen.. the fridge space and the sink space is dead to use, sink below space will be used for storing dustbin and fennel bottles,etc to store.. etc.. and if u dont have space for washing machine then that also will be used in kitchen if there is no space anywhere.. so basically make a list of ur requirement for anyone to work on it, so that they will give their best ideas on it..
