ARKWRIGHT MANSIONS
with a HISTORY
of
This part of Finchley Road, London
including Rail and Road
ground and water
Thousands of
years ago, these hills were covered in a glacier, which, having travelled from
the north, brought sands and crushed stone with it. At the end of the ice age, the melt formed torrents and river
courses, most notable being on the route of the now Fleet River. The water from
these streams and The Thames, percolated through the sand and silt, only to
collect in the basin of clay and then to be forced up again in a series of
springs, forming yet more over-ground and underground streams. London lies in
an alluvial flood plain. Under the clay dish is a layer of porous chalk. The
whole area of Camden and Hampstead is a network of springs and streams, some
from the thin chalk layer, offering a water supply and health giving wells, up
to the mid 19th century. Just to the south of Swiss Cottage, a rapid stream
flows, The Westbourne, in a conduit, under Finchley Road, through Kilburn and
on to Paddington, to become The Serpentine. There are other water courses under
these slopes, one following roughly the route of the railway. Water abounds in
this London Clay, .
GROWTH AND
EXCAVATION
London, to
the north of New Road, prior to the 18th century, was little more than open
landscape. Camden Town dates from 1791. In 1795, Hampstead and district was
described as having a small proportion of arable land, being mostly of clay,
loam, bog-earth and gravel. Finchley Road was proposed by Colonel Henry Samuel
Eyre in 1824, to open up his estate in St.John's Wood. The road was constructed
in 1826, following much opposition and in some difficulties with local owners.
The first buildings of Swiss Cottage date from 1841. Then to the north of Swiss
Cottage was the Hampstead skating rink ( 1844 ), to become The Hampstead Baths
in 1888. As London grew, so did the necessity for services. Water supplies date
from Elizabethan conduit routes and followed new development, with New River,
and culminating in the 1811 with chaos at the hands of the water companies.
London is left with an inheritance of pipes cut through and along roads, with
sewers cut in the same open manner, ensuring that there is little original
unmade ground, anywhere. Then came gas pipes, laid largely in 1820-1870, laid
in the same wide cut manner. The real destruction of the fabric of London's
ground came with the advent of the Railway and the Underground. Ground
conditions were altered forever, creating new water routes of natural drainage.
THE RAILWAYS
The
Hampstead Junction Railway ( later to become the Broad Street Line ), an
associate of the LNWR, was incorporated on the 20th August 1853, to link Camden
Town and the NLR with Willesden and the NSWJR. The line was opened 2nd January
1860. The original stations were Gospel Oak ( Kentish Town ), Hampstead Heath,
Finchley Road, and Edgware Road. West End Lane ( West Hampstead ) was not
constructed until 1888. The construction of this railway line had to be cut
right across Finchley Road, and a bridge had to be constructed to carry the
road.
THE RAIL
TUNNEL AND CUTTING
The system
employed in the construction of such tunnels and cuttings was extreme, as can
be seen in many engravings and some rare photographs of the period. The
excavations were cut in two depth stages, one about half of the depth required
and three times as wide, forming working ledges for the men and machinery (
such as it was ), and the centre trench for the final tunnel or cutting. In effect, this meant that whole streets
were lost temporarily, while work was under way, or that whole swathes of
adjoining sites were cut in such a way that the present soil is nothing more
than made up ground, as the constructed tunnels were covered over with
replenished and compacted soil.
The tunnel
on the London Midland Region ( Broad Street to Richmond ) Line - between Hampstead Heath and Finchley Road
Stations was constructed in 1859, to dimensions considerably narrower than
other tunnels and bridges, but the reasons for this do not appear to have been
recorded. The width of the line at the crossing of Finchley Road is also narrow
but, at the time, there were no buildings on the Arkwright Mansions side of the
line. It may be possible to surmise that the width of the cutting was
controlled by the width of bridge needed and its relevant cost; it could also
be surmised that there may have been some financial interest in the sites
adjoining the line which would prevent the line and tunnel being any wider, but
it has to be noted that Arkwright Road was not yet built and therefore it would
not have had any serious implications on the value of this piece of land. It is
more likely that the engineers found that the soil was particularly fluid and
that there were problems in construction ( as was found in the construction of
Belsize Park Station, where constant pumping was necessary to relieve the
excavations of the great well of water in the area).
The tunnel
was opened to traffic in 1860 and widened in 1866: In 1962, it was recorded
that it was still below normal dimensions.
Arkwright
Road was constructed in 1871. The 1894/96 Ordnance Survey map does not show Arkwright
Mansions, but the railway cutting and the road bridge are clearly defined. The
cutting extends into the rear of the present
site, adjoining Arkwright Mansions, as was fairly obvious from the
arrangements of site boundaries shown on modern OS maps.
The Central
Library ( The Camden Arts Centre, since 1964 ) was built in 1897.
ARKWRIGHT
MANSIONS
Drawings
were made of the front of the proposed building of Arkwright Mansions, in order
to request permission to construct the bay windows and balconies in front of
the Building Line, under The London Building Act of 1894, Section 73. These
flats were part of a large amount of housing development for Mr. E. J Cave and
E. A. Cave, and the drawings of the front are dated 18th June 1896, with the
approval signed on the 26th June 1896.
The original
building was constructed over the period 1897 to 1899, and was opened in 1900
and it originally had a half-mansard roof, covered in leadwork. Each of the
original dormer windows were formed in a Dutch decorated style. Only one of
these remains, today. There were also lead covered spires on two of the
dormers, besides the fine dome over the corner tower, which has survived.
Unfortunately these spires have been lost, or were not built. All other
features appear to remain as they were in 1900, but with various re-buildings
and alterations to the internal layout and with considerable alteration and
extensions to the rear of the building, some made necessary by war damage and
later contract works.
From the
observations made of the building, as work progresses on site, it became clear
that the building was commenced at the Arkwright Road end; as the project
continued down Finchley Road, so money must have become a factor, since it is
clear that the building quality reduces down the length of the building,
including workmanship and materials.
Arkwright
Mansions was built at a time when there was much experimentation and innovation
in construction and design techniques. The late 19th century had seen the
culmination of the replacement of stone with brickwork, though retaining
features and strings of stonework; this was a time of the final development of
Portland cement and its use in concrete, and in its use in simply reinforced
slabs, suspended between steelwork, also very much in its infancy. A full
description of cement, aggregate and steelwork is given on a separate page.
OUTSIDE
INFLUENCES
The most
dramatic effects on Arkwright Mansions were the result of a series of
incendiary bombs, which landed at the rear of Block C, on the edge of the
railway cutting, and a V2 rocket which landed at the rear of the Arts Centre.
It has to be admitted that the series of crack patterns in the walls of
Arkwright Mansions are a direct result of these explosions, and these will not
disappear.
Finchley
Road was widened and the area of the cutting adjoining Arkwright Mansions
covered over with a steel grillage and buildings constructed over it. The LCC
scheme drawings for the widening of the road are dated January 1962, and these
show the proposed new bridge width ( as not being part of the contract ). The
cutting was covered over c1972.
The road
widening scheme of 1968 has had some substantial effect on Arkwright Mansions,
as does the increased traffic, over the years. The original road edge was 30
feet ( 9.2 metres ) from the building main wall. The new garden walls were set
back some 15 feet ( 4.5 metres ) from their original alignment, with the
necessity to create new retaining walls and to alter the access steps.
The London
Borough of Camden had implemented works to the building in 1984, but the second
phase had been delayed, the second phase was emplaced with a new, more
comprehensive brief, in 1995.
The tunnel (
now comprising the bridge, the covered cutting and the original tunnel ) were
the subject of major works, starting October 1995 ( twelve months after the
programmed date ) to accommodate overhead electric wiring for the Eurostar.
When the line was re-opened in 1996, a survey of the resultant tunnel entrance
had shown that the present surface of the rail track ballast is some 6 metres
below the floor level of the basement of Arkwright Mansions, this at a distance
of 3 metres from the edge of the site and building of Arkwright Mansions,
it is not apparent that any work has been made to the original walls of the
tunnel.
