[1] Tremadog is a good example of a planned town,[2] with an array of Georgian architecture built in the classical tradition of the 18th century.

It towers some 100 feet (30 m) over the Town Hall, and the coaching inn,[3] giving a theatrical effect to the area.

Unlike some contemporary town planners, he was less interested in the moral reform of the inhabitants: he felt that people had the right to work, educate their children, pray, drink, gamble, save or waste money as they saw fit; and that the town should give its residents opportunities to get on with their own lives, providing that they were congenial neighbours.

The dancing room had a fireplace at both ends, a minstrels' gallery on the back wall, and five large sash windows at the front, overlooking the square.

It was reached by stairs from the tap room in the adjacent public house so that people attending a dance did not have to pass through the market area.

The house to the east of the town hall was quite shallow, allowing a stage to be built behind it, connected to the market space by a proscenium arch.

[7] Madocks believed that "in education and religion all ought to have fair play",[8] and this was reflected in the provision of a Gothic revival style church for the Anglicans and a classical chapel for the Methodists.

The entrance to the churchyard is spanned by a decorative arch of Coade stone, a ceramic material manufactured in Lambeth, London, which is in Gothic horror style, with representations of boars, dragons, frogs, grimacing cherubs, owls, shrouded figures and squirrels, while the tops of the towers are surrounded by elephants' heads.

[13] Although he provided a churchyard, no burials took place, but it was one of the few buildings in the region where services were regularly conducted in the English language.

[14] The church was fitted with box pews, cast iron windows with coloured glass, and a blue ceiling with stars painted on it.

An upper floor was fitted, and the building was subsequently used as offices by Cartrefi Cymru ("Homes of Wales"), a charity which assists disabled people living in the community.

Methodists had begun a Sunday School in a house in 1805, and in 1808 Madocks gave them the land on a 99-year lease, subject to a peppercorn rent.

[24] The building was located close to his home at Tan-yr-Allt, because the high ground behind it provided a good head of water.

It had a characteristic shallow-pitched slate roof, and Madocks instructed that the walls should be yellow, and the windows painted dark green.

[24] In the 1990s, the Tremadog Buildings Preservation Trust obtained permission for its repair and conversion but failed to acquire the site.

[24] Shops were not a common feature of Welsh villages at the time, but the Mayor opened a general store, which was supplied from London, and Madocks instructed his assistant to look out for a shoemaker, a tailor, a butcher and a weaver.

For the two inns, the nature of the reclaimed land prevented the digging of a dry cellar, and in this case, half of the scullery was replaced by a structure with a stone vaulted roof, which helped to regulate the internal temperature.

Deteriorating conditions led to annual events to tidy up the climbs between 2007 and 2010, and negotiations with the Forestry Commission resulted in invasive sycamore trees being removed in 2009.

The design of the building went on to influence how other chapels in Wales during the period were built, but the site was forced to close in 2015 as its dwindling congregation was unable to keep it open.
