Lancelot Wilson Cowman: The Master Builder of Early Moor Row

When walking past the terraces that define the industrial landscape of West Cumbria, it is easy to see them as simple, uniform rows. However, these houses were the cutting-edge "rapid-builds" of the mid-to-late 19th century, constructed to house a workforce that arrived almost overnight during the haematite boom.

To understand how these homes have stood for over 140 years, we must look at the specific manufacturers and techniques that defined the Victorian era.

1. Groundwork and Foundations

The construction of a terrace began with "shallow footings" rather than the deep concrete trenches used today.

• Initial Excavations: Builders dug down until they hit the firm subsoil. In this region, the continuous trenches for a row of terraces were often reinforced with Scoria blocks.
• The Foundation Layer: These heavy, blue-grey blocks were cast from molten blast furnace slag – a waste product from the local ironworks. Because Scoria is impervious to water, it provided a primitive but effective damp-proof layer at the base of the wall before the red brickwork commenced.

2. The Choice of Material: Whitehaven and Micklam Reds

By the mid-19th century, the demand for housing made traditional sandstone too expensive. This led to the rise of massive local brickworks that utilised the fireclay and shale found in West Cumbrian coal seams.

• Whitehaven Brick & Tile Co. Ltd: Established by 1857 (originally operated by George Wintle), this works was a primary supplier of "common" bricks for the region's expansion. Their bricks were fired from carboniferous shale, resulting in a dense, smooth-faced product that could withstand the salt-laden Cumbrian winds.
• Micklam Firebrick Works: Located at Lowca, this works was part of the industrial empire of Bain & Co. (from 1874). They utilised fireclay from the Harrington No. 10 Colliery. While many Micklam bricks were "firebricks" intended for lining furnaces, they also produced exceptionally hard "engineering" bricks used for the main elevations of local housing.
• Extreme Hardness: Both Whitehaven and Micklam bricks were fired at higher temperatures than standard southern clay bricks. This created a masonry unit that is famously difficult to drill into – often described as "iron-hard."

3. The Solid Wall Build

In the late 1800s, "cavity walls" were not yet standard. These houses were constructed with solid 9-inch masonry.

• The Double Brick Method: The wall is two bricks thick with no air gap. To prevent the two layers from separating, builders interlocked them using "headers" (bricks laid perpendicular to the wall).
• Bonding Patterns: Look at the exterior face. If you see a pattern where every third or fifth brick is a short end, you are looking at the "bond" that ties the front of the house to the back. Common local patterns include English Bond (alternating rows of long sides and short ends) or Flemish Bond.

4. The Essential Component: Lime Mortar

The most critical part of the build was the mortar. In the Victorian era, this was a mixture of sand and lime (frequently mixed with coal ash, known as "ash mortar").

• Breathability: Unlike modern cement, lime mortar is porous. It acts like a "wick," allowing moisture to travel through the joints and evaporate away.
• The Danger of Cement: If these houses are repointed with modern Portland cement, the moisture becomes trapped. Because Whitehaven and Micklam bricks are so dense, the trapped water is forced to the surface of the brick. During a frost, this water freezes and expands, shattering the hard face of the brick. This process, known as spalling, is the leading cause of masonry decay in Victorian terraces.

The houses of the haematite era were built with a durability that mirrored the industry they supported. From the slag-based Scoria foundations to the shale-fired Whitehaven and Micklam bricks, they were designed to be permanent, provided they are maintained with the breathable lime materials they were built with.

The Man Behind the Stone

While many Victorian builders remain anonymous figures in history, the "LWC" mark on Dalzell Street provides a rare surviving builder’s datestone which strongly aligns with a known local Master Builder operating at the correct time and location.

Lancelot Wilson Cowman was an Egremont-based Master Builder whose career coincided with the most intense period of industrial expansion in West Cumberland. Born in Egremont around 1811, Cowman established himself as a contractor during the years when haematite mining and railway construction were transforming rural parishes into industrial settlements.

Census records from 1861 list Cowman at 82 Main Street, Egremont, employing ten men and two boys - a workforce consistent with firms capable of delivering full terraced housing developments. When considered alongside the 1859 datestone on Dalzell Street, this provides strong circumstantial evidence linking Cowman to the earliest phase of Moor Row’s housing construction.

A Business Built on Haematite

The success of Cowman's business was inextricably linked to the iron ore boom. As the mines expanded, the need for permanent, sturdy housing for workers became a crisis for local landowners. Cowman was ideally positioned in nearby Egremont to service this demand. His work is characterised by the use of locally produced red brick, with sandstone used for detailing such as datestones, lintels, and architectural dressings.

Building the first terrace on Dalzell Street in 1859 was a significant undertaking. It required the coordination of masons, joiners, and labourers to create the earliest permanent street in what would become the village of Moor Row. The datestone left behind was more than just a chronological record; it was a mark of professional pride and a permanent advertisement for a business that stood at the intersection of craftsmanship and the industrial revolution.

Cowman's presence in the 1861 records as a Master Builder confirms his status as a respected figure in the local building trade, responsible for the physical expansion of the towns and villages that housed the miners, railwaymen, and their families. Today, his initials remain a quiet testament to a man who literally laid the foundations of the community.

The First Residents: 1861 Census

The following record lists the heads of household for Dalzell Street during the 1861 Census. These individuals were the first occupants of the terrace completed in 1859 and attributed to Master Builder Lancelot Wilson Cowman based on census and datestone evidence. The residents provided the essential labour force for the local haematite mining and railway sectors.

Address	Head of Household	Age	Occupation	Birthplace
No. 1	William Johnston	34	Iron Ore Miner	Egremont, Cumberland
No. 2	John Thompson	29	Railway Labourer	St. Bees, Cumberland
No. 3	Thomas Cummings	41	Iron Ore Miner	Ireland
No. 4	Isaac Bragg	38	Iron Ore Miner	Gosforth, Cumberland
No. 5	Robert Telford	31	Iron Ore Miner	Egremont, Cumberland
No. 6	Joseph Richardson	28	Iron Ore Miner	Cleator, Cumberland

Architectural Evidence

• The datestone bearing the initials LWC and the date 1859 strongly suggests a link to Lancelot Wilson Cowman. As a Master Builder based in nearby Egremont, Cowman's firm provided the professional capacity required to establish among the earliest permanent terraced streets in what would become the village of Moor Row.
• The terrace was built to accommodate the workforce necessary for the expansion of the local mines and the Whitehaven, Cleator, and Egremont Railway – a project that defined the industrial character of the region.
