This looks like the sale of land opposite St Barnabas church/chapel on High Street (Lichfield road turnpike). (The land may have later been broken down into smaller lots). This advert must be referring to the land upon which the Easy Row houses were eventually built, with the brick kilns and quarry situated behind. This is discussed in the High Street Erdington thread.
If this is correct, the brickworks must have been "Erdington Brickworks" (re post #39 - Richard Thomas 1814-17) and at some later point acquired by the Machin's (it's unlikely they had Nocks brickworks the only other identified brickworks on Holly Lane).. Perhaps the Machins acquired the land at the time of this advert in the 1830s, followed by the building of the Easy Row 2 storey terraced cottages sometime soon after.
