The 2004 building assessment

see also - the 2007 building survey

The factory buildings at Royal Worcester were assessed in 2004 as part of the overall programme of investigation into the historical heritage of the site. 

The  assessments are based on a fairly rapid study of the site, which at the time was a busy working factory in which some areas were difficult to access. They were based on the significance of a building or structure within the factory context, rather than beyond its boundaries. 

Subsequently, in 2007, a major building survey was carried out and the results are currently being worked on.

 

 

Buildings within the Royal Worcester Porcelain Factory on Severn Street

The majority of the factory buildings were of low significance, being modern lean-to additions to older Victorian buildings.  The additions do reflect the growth of the factory complex over time and add group value to the who complex. 

There were also buildings of medium significance.  The most prominent of these is the Old School Building in the visitors car park.  The building was the Royal Worcester seconds shop.

There were two Grade II* listed buildings within the complex – but only one in the study area (The Old Mill, Building D) – that were clearly of national significance.  The Old Mill was one of only two surviving examples of its kind in the country. 

The most significant buildings within the site are discussed below.

 

The Old School Building

Building D: The Old Mill

Description

 

The brick-built Old Mill complex was the most important of the buildings on the Royal Worcester Porcelain site and the only one in the study area to be listed.  This description is only an outline one given the building’s obvious importance and the fact that the only proposals for it are presently associated with retention and refurbishment within the present scheme:-

It consists of the processing floor wing, the attached engine house, boiler house, coal stores and integral water tank.  The main western section is of three storeys and seven bays, the bays articulated by boldly rusticated brick pilasters more reminiscent of an early-18th century Baroque country mansion than a mid-19th century industrial building.  There is, however, only a very simple flat cope at the wall heads with only the slightest hint of a cornice.

In most bays there are paired windows at each level, many of the upper ones blind; many windows have retained their original cast-iron framed glazing.  There are also some primary arch-headed doorways at ground-floor level.  The window sills form continuous brick band courses between the rusticated pilasters.  On the south elevation the ground-floor pairs have ached heads and the upper ones are all flat headed; on the north elevation there are arch-headed windows at first-floor level too. The top-lit roof is supported on timber trusses.

Internally, the ground-floor has been somewhat altered but there are still primary working floors complete with the bone-grinding bins at first and second floor levels – extremely rare survivals.  The paddles in the bins are worked by bevelled gearing from shafts powered from the adjacent engine house to the east.  Much of the apparatus, original and later, survives in situ.

The engine house is a cross-wing towards the eastern end of the complex, taller than the sections to either side.  In the gable ends there are single arch-headed recesses in the brickwork containing the paired windows of the upper floor levels.  In the main eastern facade the central section is recessed as if between broad panelled brick pilasters at either end. 

The windows are treated virtually as full-height ones, interrupted only by the narrow bands of brickwork between the flat heads of the lower pairs and the sills of those above.  The upper windows in each case have a semicircular arched head.  The verged glazing retains traces of coloured or stained glass.

The engine house is topped by a brick cornice, plain on the flanks and the rear but elaborately decorated with dentilled brick work on the main east elevation.  Under the central recessed portion of the cornice there is even a series of projecting vertical brick features, perhaps intended to echo the triglyphs and metopes of Greek Doric architecture. 

The original steam engine has been removed and had been replaced by a more modern engine, but there are still traces of the sockets in the brick work relating to the manner of its design, as well as other related features.

To the east of the engine house is a low, single-storey, block, clearly contemporary; it has two bays in its main elevation articulated by plain brick pillars and decorated with a dentilled cornice.  In each bay is a segmental headed window with cast-iron glazing.  This was evidently the boiler house, and its roof is made up of a large water tank.  At its north-western corner is the impressive stack, with a base/plinth decorated with more dentilled brickwork and a tall octagonal brick stack, slightly tapering and surviving almost – but not quite – to full height.

The last portion of the original complex is another single storey block, lower than the boiler house and running along its south end and back westwards along part of the engine house.  This has a blank canted east wall, with dentilled cornice and a three-bay south wall – two with segmental headed windows and the third, at the east end, with a large and remodelled doorway.  This was presumably the coal store for the steam engine.

Discussion

This is a remarkable survival within an industrial complex, retaining all of its main components.  In order of use these are the coal storage area, water tank, boiler house, chimney, engine house – presumably a fairly small beam engine – and the processing floors with their bins and shafting.  Obviously the steam engine and the boilers have been removed, but their original positions can be identified.

This was an expensive investment in the works, in place by 1863 but probably not built much earlier.  The cost of the machinery within is expressed in the flamboyant Baroque architecture without, and the engine house itself was given the typically rich treatment as a miniature cathedral of industry.  The survival of the crushing bins and shafting is almost unique.

Building E: The China Goods Warehouse

Description

This two-storey range has a rather asymmetric footprint, basically trapezoid in plan, widening towards the main east gable to the fossilised lane through the works.  Originally there was an indent in the south-western angle of the building, though this has been in-filled by a slightly later extension.

It is brick-built with the red machine-made bricks laid mainly to a simple English Bond and articulated by brick pilasters.  Each of the recessed brick panels between the pilasters is topped by dentilled moulded brick cornices

The main eastern elevation is disfigured by an ugly modern steel-framed and steel-clad lean-to along its full width, and its ground-floor openings have been blocked.  The facade is articulated by pilasters into five bays, the central bay of double width and topped by a raised coped gable (very) vaguely reminiscent of churches of 13th century Lombardy. It is a fake gable, purely for decoration, as the roofs behind run parallel to it.  The dentilled brick cornice of this central bay is taken up in a semicircular arch up and over a roundel in the gable; that gable is also topped by similarly detailed at the base of its coping.

On this elevation there were originally six windows at each floor level, one in each of the side bays and two in the central bay.  These have segmental brick heads and bold projecting moulded brick sills and originally had cast-iron glazing.  One, on the ground floor, appears to have been converted into a doorway before it was blocked.

The visible north side elevation is of eight bays in all, including a narrow entrance bay just to the west of centre.  The window details are identical to those on the eastern gable; to the east of the entrance bay a ground-floor window has been blocked and replaced by a doorway and another, in the second bay from the west, has been converted into a doorway, its upper portion retained as a fanlight.  There has been some modernisation of first-floor windows.

The south elevation is now a party wall between this range and the adjacent Finished Goods Warehouse (Building I).  Because of this, it has been considerably altered but survives better on the ground floor than it does at first-floor level, where original window openings have been removed and replaced by inserted open doorways.

Because of the original shape of the building, its western gable is much narrower than its eastern gable. Architecturally, it is to all intents and purposes a deliberate repetition of the central bay of that main facade.  The later infilling of the ‘cut-out’ in the south-western part of the building obscures the external details in that area, and the southern side elevation is obscured by the later buildings to the south.  That elevation has clearly been considerably altered as well.

The slate-covered roof structure is in two separate parts corresponding to the different parts of the building.  The wider eastern section is covered by a pair of parallel four-bay hipped roofs at right-angles to the main coped gable of the eastern facade to the old lane.  The roof over the narrower western section is of three bays and at right-angles to the other section.

All of the trusses are of the same and rather unusual composite design used elsewhere on other buildings within the complex.  The principal rafters are of sawn timber, their ends are housed in cast-iron shoes.  From the upper, or apex, shoe a vertical wrought-iron suspension bolt drops to an interlocking and bolted junction where the two further sections of wrought-iron that make up the tie-beam meet the feet of the pair of cast-iron cruciform-sectioned braces to the rafters.  The trusses carry a single tier of chocked purlins.

Internally, the wider eastern section on the ground floor level is a large store or workshop interrupted only by the slender cast-iron columns that support the timber bridging beams of the floor above.  The narrower western portion consists of a pair of full-width spaces.  The first-floor level is accessed by way of a bridge over the alley-way on the north side and has a similar layout.  In the wider section the space is interrupted only by the cast-iron columns under the valley between the two roof piles.  There is an oddly angled iron girder along the western side at this level associated with the roof structure and also the odd footprint of the building.  The narrower western section is mainly a single workshop open to the roof.

Discussion

Building E fronts onto to the fossilised lane running through the porcelain factory and it is clear from the degree of decoration to its gable end to the lane that this was then the most important facade.  This would suggest that the lane was still then an important thoroughfare.  Despite unsympathetic modern accretions it is still a visually attractive building, though one that has been considerably altered internally.

Its overall design, generally detailing, and the roof structure is very similar to a distinct group of buildings on the site, that include Buildings K2 (Binns Building East Wing), Building R (China Decorating & Warehouse Range) and probably once Building S (Spray Glazing Range) - all presumably the work of the same architect in the same period, probably in the 1870’s. 

 

Building K1: Binns Building North Wing

Description

The northern ‘cross wing’ of the Binns Building was built soon after the other two parallel ranges but in the same general style.  It is a tall three-storey brick-built range, situated between the fossilised lane through the works and the canal, with gables to each.

It is seven bays long and three wide above a basement.  The bays are articulated by brick pilasters and the recessed panels in between are topped by ornately moulded dentilled cornices.  The plinths of the pilasters are decorated with chamfered blue engineering brick.

In each of the north and eastern gable bays there are window openings at all three main floor levels.  These have segmental brick heads and engineering brick sills and contain cast-iron glazing, possibly original.  There are no windows in the panels on the south side elevation.

In the eastern gable end, facing the canal, the southernmost ground-floor window has been crudely converted into a doorway.  Beneath a concrete and steel structure associated with the emergency fire escape is the entrance into the basement and a visible basement window, plainly detailed.

In the western gable end, facing the lane, there are original doorways in the end bays with segmental arched heads and three-light fanlights above the doors.  In between there was, originally, a wide window but that has been carefully blocked in brick.

Both gable ends have coped gables in which the intermediate bay pilasters continue past the main ‘cornice’ level.  The base of the triangular copings are treated in the same decorative manner as the cornices to the side panels.  In the centre of each gable is a brick-framed roundel containing an ornately moulded cast-iron vent.

The five-bay roof structure bears no direct relationship to the seven-bay design of the wing’s side walls but is presumably primary.  It is supported on a series of timber bolted king-post trusses, the tops of which are hidden by a high ceiling.  Apart from the stairs at the western end of the range, there are, or were, large single full-length and width workshops at each floor level, interrupted on the ground and first floor levels by the intermediate columns supporting the main floor beams. 

Discussion

This was the last part of the Binns Building complex to be completed, for whilst the parallel ranges to the south are shown on the 1884 Ordnance Survey map, this one is not.  In addition, whilst its detailing is generally similar, there are some differences, including the use of engineering brick for the window sills instead of moulded red brick.  There seems to be little doubt that it was built around the mid-1880’s and could have been under construction when the map was being surveyed.  It appears to have provided additional workshops or warehouse space on all three floors.

Building K2: Binns Building West Wing

 Description

The West Wing of the Binns Building lies parallel to the fossilised lane through the works and is contiguous with the slightly lower East Wing (Building K3).  To the north there is a very short single-bay link to the slightly later North Wing (Building K1), and the evidence of the decoration in this range’s northern gable shows that it was built before that range.

It is a two-storey range of eight bays, built in machine-made red brick laid mainly to an English Bond.  The bays are articulated by brick pilasters that have a vague decorative hint of brick capitals.  The recessed panels between are topped by ornate dentilled cornices.  On the external west wall there are generally two windows at each level in each bay.  Each of the window openings has a segmental arched brick heads and rounded brick sills.  The window glazing is generally not original and quite varied.

In the northernmost bay of this wall there is a possibly primary doorway and a small narrow window to its south.  There is another doorway towards the south end.  The main entrance is in the third bay from the north.  This has double doors under a segmental brick head and is flanked by a pair of tall recessed brick panels.

The gable ends are of three bays, the middle bay wider than the outer ones.  Each is topped by a coped gable in which the decorative dentilled brickwork in the panel cornices is repeated under the coping and the pilasters are taken up to it as well.  In the centre of the gables in a brick-framed glazed roundel.

In the south gable end there are four windows at ground-floor level of the standard pattern seen in the side wall – two in the central bay and one to each side.  At first-floor level there is just a pair of narrower but taller windows in the central bay with semicircular heads.

The roof slopes are slated.  The roof is in two sections but of a common pitch.  The northern portion is fairly simple but its trusses are hidden by the surviving ceilings; it also has large skylights.  The southern section has a low central clerestory and decorative cast-iron trusses. Surviving at the apex to either end of the clerestory section are two tall cowl vents, probably original to the building.

The ground-floor is divided up into various workshops and stores and different sizes and dates.  The main entrance doorways lead into an ornately tiled lobby area at the foot of the stairs up to the first-floor, reached through a second set of double doors.  The stairs have ornate cast-iron balusters at first-floor level.

The southern part of the first floor is a fairly impressive open space, formerly the show room, and it is open to the most remarkable element of the range - its roof.  This has richly decorated cast-iron trusses and a central clerestory at the southern end.  To either side of the clerestory the ceiling is coved.  The cornice has a continuous Greek Key decoration and the framing at the base of the clerestory, a running floral pattern.

Most of the original cross-wall between the two halves of the building at first-floor level has been removed and the gap spanned by a RSJ.  The northern portion is now all open, but the evidence of the surviving pattern of moulded cornices in the ceilings clearly shows that it had once been divided up into three spaces.  These were: a large landing at the head of the stairs on the east side; and two heated rooms on the west side.

 Discussion

This range was probably built in the early-1870’s, at the same time as the adjacent East Wing (Building K3 - see below).  Despite its proximity to the kilns in the adjacent wing, it was evidently a high status building, especially at first-floor level where there were two heated rooms, an elegant stair landing and a large showroom lit by an ornate clerestory.

 Building K3: Binns Building East Wing

 Description

The East Wing of the Binns Building is built parallel to, and at the same time, as the West Wing but, whilst externally it has been relatively unaltered – apart from the loss of its projecting kilns – internally it has effectively been gutted and rebuilt.  It is presently the Moulds Shop.

Built of red brick laid to an English Bond, like the West Wing it is eight bays long but its external side wall, facing the canal, is much plainer.  There are no pilasters but there is a decorative dentilled eaves cornice.  The windows have segmental brick heads.

The end walls are of two bays and have stone-capped coped gables; these have dentilled brickwork beneath them and roundels, but there are no pilasters in these elevations.

The roof is slated.  In the slating there is no hint of the positions of the former kilns that the range originally housed, indicating that the whole roof has been completely re-slated since they were removed.  The roof trusses are the unusual composite trusses used elsewhere in other buildings within the complex. 

The principal rafters are of sawn timber, their ends are housed in cast-iron shoes.  From the upper, or apex, shoe a vertical wrought-iron suspension bolt drops to an interlocking and bolted junction where the two further sections of wrought-iron that make up the tie-beam meet the feet of the pair of cast-iron cruciform-sectioned braces to the rafters.  The trusses carry a single tier of chocked purlins.

The timber floor is clearly inserted and the present internal arrangements clearly post-date the removal of the original kilns originally housed within this part of the complex.

Discussion

This range was probably built in the early-1870’s, at the same time as the adjacent West Wing. It is known from cartographic and photographic evidence that it originally housed four large bottle kilns but that these were removed in the mid-20th century and the first-floor then added. 

It has the same type of unusual composite roof structure as Buildings E (China Goods Warehouse), Building R (China Decorating & Warehouse Range) and probably once Building S (Spray Glazing Range) - all presumably the work of the same architect in the same period, probably in the 1870’s. 

Apart from the loss of its original kilns, the range is, externally, relatively unaltered.  Internally, it was radically changed when the kilns were removed, lessening its historical and architectural integrity.

Building M: The Grinding & Polishing Shop (West)

Description

This is a substantial brick-built two-storey range of eight bays articulated, internally and externally, by brick pilasters.  Little of the exterior walls are visible because of the buildings butting up against it.  As such, only the first-floor portion of the western gable end and the very top of the eastern gable end are truly external.  At ground-floor level, most of the gable walls have been removed.

In the gable ends there are four bays – the middle two set more closely together than the outer ones.  There were originally windows in each bay with segmental blue engineering brick heads; those at first-floor level in the west gable survive, those in the east gable have been blocked, apart from one that has been converted into a doorway.

Each of the gable ends is topped by a simply decorated coped gable hiding the main slated roof.  The roof structure is supported by sawn-timber bolted queen-post trusses, with braces from both tie-beam and queen posts to the principal rafters.  The trusses support two tiers of chocked purlins.

The interior consists mainly of large workshops on both floor levels, the ground-floor one interrupted only by pairs of columns supporting the floor beams.  There are, however, few surviving fixtures or fittings of historical significance.

Discussion

This range clearly predates the much altered building butting against its east gable (Building N, the Grinding & Polishing Shop (East); the decoration of that range suggests an 1870’s date, so this one must predate it and could be as early as the 1860’s.

It has been considerable altered and is hemmed in by other buildings.  Internally it has been much altered but retains its original roof structure – significantly a timber trussed one.  It may represent one of the first buildings of the complex added as it was expanded southwards.
