The total cost of the building, including land and furnishings, was £76,679, making it the most expensive church to be built in London since the rebuilding of St Paul's Cathedral. It was designed to seat 2,500 people. Architecture The church is in a Greek revival style, using the Ionic order. It is built from brick, faced with Portland stone, except for the portico and the tower above the roof, which are entirely of stone. All the external decoration, including the capitals of the columns is of terracotta. The Inwoods drew on two ancient Greek monuments, the Erechtheum and the Tower of the Winds, both in Athens, for their inspiration. The doorways are closely modelled on those of the Erechtheum, as is the entablature, and much of the other ornamentation. Henry William Inwood was in Athens at the time that the plans for St Pancras were accepted, and brought plaster casts of details of the Erechtheum, and some excavated fragments, back to England. The west end follows the basic arrangement of portico, vestibules and tower established by James Gibbs at St Martin-in-the-Fields. The octagonal domed ceiling of the vestibule is in imitation of the Tower of the Winds, and the tower above uses details from the same structure. At the east end is an apse, flanked by the church's most original features: two tribunes designed in imitation of the Erechtheum, with entablatures supported by caryatids. Unlike those on the Erechtheum, each caryatid holds a symbolic extinguished torch or an empty jug, appropriate for their positions above the entrances to the burial vault. There is a stone sarcophagus behind the figures in each tribune, and the cornices are studded with lion's heads. The caryatids are made of terracotta, constructed in sections around cast-iron columns, and were modelled by John Charles Felix Rossi, who provided all the terracotta on the building. The upper levels of the tribunes were designed as vestries. Access to the church is through three doorways ranged under the portico. There are no side doors. Inside, the church has a flat ceiling with an uninterrupted span of , and galleries supported on cast-iron columns. The interior of the apse is in the form of one half of a circular temple, with six columns, painted to imitate marble, raised on a plinth. The crypt, which extends the whole length of the church, was designed to contain 2,000 coffins, but fewer than
