This is another church by Mallinson and Healey (seen above from the northeast) perched on the edge of a hill, and although it is not one of the partners' best, it would obviously have looked more impressive before it lost its spire.  (The photograph, below left, shows the view from the churchyard.)  As it is today, it consists of an aisled nave with a N. porch and tall but shallow transepts, and a chancel with a south tower rising in four stages to ugly, three-light bell-openings that have lost all their tracery.  The style is (or was) the late geometric of c. 1310, a style it shares with All Saints’, Salterhebble, and St. John’s, Clifton, both of which are in Calderdale and both and both of which were designed the same year as St. Thomas's, namely 1857.  Windows lights in all parts of the building are almost entirely trefoil-cusped, the N. and S. transept windows have tracery composed of three encircled cinquefoils, and the five-light chancel E. window (illustrated below right) features, in the apex, an encircled trefoil surrounded by a wheel of trilobes, and outer lights subarcuated in pairs above trilobes and encircled sexfoils.  This is now the best architectural feature remaining.

 

Inside the church, the five-bay nave arcades are formed of double-flat-chamfered arches supported on octagonal piers, as they are in the majority of the partners’ cheap churches in the mid-1850s.   (See the interior view of the church below, looking east.)  The transepts communicate with the nave through the westernmost arch of the aisle arcades, and the chancel arch adopts a similar form, albeit slightly larger.  The arch from the chancel to the vestry, located in the tower, bears two flat chamfers which die into the jambs.

 

The Leeds Intelligencer, reporting on the opening of the church on 28th April 1860 (p. 7), recorded the cost of the building to have been:

...about £3,000, including the purchase of a grave yard.  The site of the church was given by Mr. Alderman Green, who has acted as chairman of the building committee, and shewn great liberality and interest in the building of a church in that neighbourhood.  The edifice is a plain, but withal handsome structure, in the Gothic style... It accommodates about six hundred persons... The endowment fund is not yet completed, the sum wanting being about £70.

 

Indeed, there was a much larger sum wanting for essential repairs to the church at the time of this visit, and with a very small congregation, the church was facing closure.
