Main House Jimbour House comprises three bays; two longitudinal projecting end bays with a central transverse bay, lined on the principal façade with an open terrace on the upper level supported on
Doric order columns on stone
plinths, paired in some places. Centrally located on the principal façade is a semi-circular projection, apparent in the roofline and through both storeys. This defines the principal entrance. The roof is steeply pitched,
hipped over the three bays of the building and clad with Welsh slates. Dominating the roofline are four large brick chimneystacks with
corbelled caps. Projecting from the two ends of the building are classically inspired single-storeyed wings with
parapets concealing their rooflines. The terrace on the upper level of the house has been built in at the rear and there is a single-storeyed brick kitchen block below it. The interior of the house has a wide hall running for most of its length on both levels. Both levels of the hall have a fireplace on one wall, reminiscent of the galleries in English country houses used as winter
promenades. The joinery is of a high quality. The ground floor contains receptions rooms, a billiard room and a large, square entrance hall with a bedroom opening off it. The upper floor echoes the layout of the ground floor and has an open paved terrace, bedrooms, and suites of rooms. One bedroom has two hunting scenes frescoes (drawn directly onto the plaster of the walls) dated 16/11/1879.
Outbuildings To the west/southwest of the main house is a large, rectangular building of pecked sandstone blocks, which now accommodates residential accommodation on two levels. Originally constructed as a store, evidence remains of the massive barred windows and
catshead to the upper level. The building has a
gabled roof with close eaves, clad in corrugated iron, into which dormer windows have been inserted. The end walls have arched openings on the upper level, which are now glazed. One of them has a small balcony. The building has
sash windows and one of the external doors has a mail hatch from the days when this building was used as a post office. Partition walls and some ceilings inside are timber. One of the rear rooms has a blue-green lime wash finish that is believed to be early.
Bluestone Building (1868 residence, remodelled in the 1870s as a kitchen and staff quarters and in the 1920s as men's quarters) To the rear of the main house and separated from it by a garden area, is a single-storeyed, low-set bluestone building with sandstone quoins, rectangular in plan, which was formed from the lower storey of the 1868 main homestead residence. It has a hipped roof clad in corrugated iron. The wall at the eastern end of the building is of
weatherboards with bricks infilling between the
quoins, following the removal of an adjoining wing. The rooms are arranged in a linear fashion, each opening onto a
verandah along the southern side. The interior has fibrous cement linings and battened ceilings. One room has a brick fireplace.
Chapel Finished in 1868. At some distance west from the main house and north of the main drive () is a simple timber chapel set on low stumps. It is rectangular in plan with the sanctuary under a separate roof at one end and a porch at the other. The main roof is clad with late 20th century tiles and has a small
belfry. The roofs of the belfry, sanctuary and porch are clad in corrugated iron. The porch roof was for a period raised to accommodate a small film projection room above the door, illustrating the multi-functioned use of this building which for a time housed the Jimbour school. Inside, the main roof is supported on
scissor trusses and is ceiled with timber. The
nave is lined with composite board and is lit by small
lancet windows with coloured glass. There are carved altar rails and
font and timber pews.
Water Tower (1870s, converted 1950s into residential use) West of the chapel and the main drive is a tall timber tower (), 4 storeys in height and square in section, with walls sloping inwards, supporting a large, square, cast iron water tank. The framing is of trimmed tree trunks and hand hewn timber, clad externally with weatherboards dating to the 1870s. The interior now accommodates residential use and is lined with
fibrous-cement sheeting and timber cover strips. The ground floor has modern metal-framed sliding doors and windows and contains a visitors' centre and gift shop. The top storey room is decorated with several
naïve paintings, executed between 1924 and 1956 by a former employee at Jimbour. From this level, there is external access via a timber ladder to the water tank above. A single storey timber extension has been added to one side.
Bell Memorial The Bell Memorial is located to the south of the water tower. Metal railings surround the memorial, which comprises a painted masonry obelisk decorated very simply with a border of
acanthus below the plinth on which the shaft rests. The memorial below this is square in section with a plaque to each face, two of which are inscribed in memory of Sir Joshua Peter Bell who died in 1881 and of his son Joshua Thomas Bell who died in 1911. A third plaque was inscribed in memory of Lady Bell in 2002. The other face is blank.
Stone Store To the west/southwest of the main house is a large, rectangular building of pecked sandstone blocks, which now accommodates residential accommodation on two levels. Originally designed by notable Queensland architect Benjamin Backhouse and constructed as a store, evidence remains of the massive barred windows and
catshead to the upper level. The building has a gabled roof with close eaves, clad in corrugated iron, into which dormer windows have been inserted. The end walls have arched openings on the upper level, which are now glazed. One of them has a small balcony. The building has sash windows and one of the external doors has a mail hatch from the days when this building was used as a post office. Partition walls and some ceilings inside are timber. One of the rear rooms has a blue-green lime wash finish that is believed to be early. == Culture ==
