Situated in a conservation area, much of the architecture is listed, including the distinctive Lansdown Estate.

Henry purchased the Reverend de la Bere of Southam's estate in 1801 and by 1804 had constructed his own residence of Hygeia House[2][3][i][ii] The increasing fashion for 'taking the waters' encouraged him to develop Montpellier Spa, opening a wooden pavilion with landscaped gardens and promenades in 1809.

In 1825, Pearson also had Papworth rebuild the Montpellier Pump Room with a domed rotunda that still stands today.

By 1830 though, Pearson Thompson was in financial difficulties and engaged the architect brothers Robert William and Charles Jearrad as co-developers.

They also designed the large 2,000 seat Christ Church, built from 1837 and consecrated in 1840, to attract residents of the right quality to their new development.
