In January 1823, Baring invited Charles Robert Cockerell to visit and discuss proposed additions.
Designs were ready by June and included an elegant dining room (now demolished) and orangery conservatory (approx 80‘x50’) with a four columned Ionic portico on its east elevation.

In December 1823 Baring spent two days discussing the conservatory design with Jones (of Jones & Clark) and the order was placed the following March.
There were two large rectangular planting beds running the length of the building with a central and an outer walkway all the way round, paved in Portland stone.
Slim hollow cast iron columns held up the roofs and channelled rainwater into a large reservoir under the portico which supplied the house and the conservatory.

The external elevations were rendered pilasters with full length glazed sashes of rolled iron with copper sash bars.
The side lights and the doors at each end were mahogany glazed with British glass.

In 1826, writing in the Gardener's Magazine, Baring’s head gardener, Peter McArthur, gives technical details of the building, the balance of humidity, light and heat, how the beds were constructed, the mix of soils, a list of about 150 plants “the principal and most conspicuous sorts”.
The vestibule inside the east end of the conservatory had standing boxes of orange trees, camellias, proteas and magnolias which were brought out onto the terraces for the summer (picture).

Around this time terrace gardens with fountains and balustrades were finished.

In January 1827 Jones & Clark wrote to Baring “We think we may safely venture to affirm that the conservatory at The grange is not surpassed by anything of the kind in the United Kingdom.
”“The whole of the conservatory, with the exception of the brick and stone work, was executed, and its different parts put together at our Birmingham and aftwards [re-]erected in its present situation by our own workmen.”
This use of prefabrication was revolutionary and a precursor to Paxton's Crystal Palace.

In June 1828 Cockerell took his new bride, Anna Maria (née Rennie) to The Grange.
