Type:
Poured In-Situ |
 |
Construction
8" thick solid no-fines clinker concrete walls in the period 1919 to 1928. 1925
to 1945 cast in situ cavity walls, 3" thick inner and outer Ieaves with 2" cavity, usually
finished externally with stone dashed render coat. Post 1945 (the majority of houses) cast
in situ concrete walls, inner and outer leaves of 3" thickness separated by a 2" cavity,
reinforcement in both skins located in 4 horizontal bands above and below window openings. |
Common
Identifying Features
Line of wall lift evident in horizontal line within roof space, in
roof space internal face of walls aggregate not so coarse as Wimpey No-Pines construction.
Ventilation through external walls rectangular in many examples of this construction. |

Type:
Poured In-Situ |

Construction
Solid cavity wall types. A cast in situ concrete form of construction, first
used in 1952 but mainly in the period 1962 to 1981. Construction substitutes mass concrete
for the inner blockwork walls of traditional housing. Solid wall types 225mm thick cast in
lightweight concrete, rendered externally. Cavity wall types with an 'inner leaf of
100-125mm thick concrete. |
Common
Identifying Features
None known. |

| Name:
Wimpey No-Fines |
Type:
Poured In-Situ |
 |
Construction
Is in situ cast no-fines concrete. Before 1951 external walls were commonly
12" thickness, 1951 to 1964 external walls were commonly 10" thickness, after 1964 walls
were commonly 8" thickness. Gable walls maybe clad with a masonry outer leaf tied to the
cast in situ concrete with wall ties. Up to DPC level the external walls maybe of masonry
construction. Post 1964 examples of this construction can be dry lined internally and some
external surfaces of walls maybe tile faced or weather boarded. Reinforcement commonly
incorporated at eaves level and at a level to tie in with reinforcement over ground floor door
and window openings. |
Common
Identifying Features
Measurement of the external walls at some 12" thickness,
coarse aggregate evident to wall face concrete mix in roof space. Ventilation through
external walls circular in many examples of this construction. |

| Name:
Boot |
Type:
PRC |
 |
Construction
External walls trained in concrete piers or columns, fixed in pairs to create a
cavity wall. Inner and outer leaves formed in clinker blocks or concrete panels, plastered
internally and rough cast rendered externally. Roots pitched and often hipped with
conventional tile coverings. |
Common
Identifying Features
Front ground floor bay to some houses. Pattern of cracking
to external rendering may reveal structure beneath. |

| Name:
Cornish Unit |
Type:
PRC |
 |
Construction
Post and panel construction. Exposed concrete columns at 36" to 40"
centres, carrying concrete slabs to form the leaves of cavity walls. Slab depths vary from
9" to 24" depending on type. Traditionally constructed Mansard roofs (Type I Cornish Units),
although some were built with conventional hipped roofs and tile hung upper elevations.
Type 2 units may have post and panel construction to upper elevations beneath a hipped
roof. |
Common
Identifying Features
Exposed post and panel construction, Mansard roofs. |

| Name:
Dorran |
Type:
PRC |
 |
Construction
Storey height narrow pre-cast concrete panels rising from a kerb unit At
ground level and a concrete ring beam at first floor level. Panels bolted together horizontally
and backed by a Timber frame internally. Scaled externally by mortar pointing or Bitumastic
Tape beneath a textured finish. Roofs are twin pitched and tiled often with vertical boarding or tile hanging to gable ends. |
Common
Identifying Features
Outward slope to first floor ring beam, vertical boarding to
gable end. |

Construction
Storey height concrete panels and columns secured by steel angle brackets.
Concrete beams run from front to rear at first floor and eaves height. Cavity built walls with
concrete panels forming the outer leaf and concrete slabs forming the inner leaf. Panels
have an exposed aggregate finish but may be tendered throughout or to one storey only.
Flipped and tiled roof. |
Common
Identifying Features
Panels set between columns at ground floor level and
overlapping columns at first floor level creating an oversailing first floor. |

Construction
Pre-cast concrete storey height columns, kerb units and ring beams
concealed within an external cladding of concrete panels with staggered vertical joints. The
Mansard first floor and roof is tiled and of traditional construction, carried oil concrete
cantilever units from the ring beam. |
Common
Identifying Features
Mansard first floor and roof, staggered vertical joints to
panels give appearance of blockwork. |
