The Split House and Victorian Reputation
Jekyll's property brilliantly symbolises his dual personality. The main house has "a great air of wealth" and appears well-maintained, whilst the laboratory door is "a sinister block of building" showing "prolonged and sordid negligence." This physical split mirrors Jekyll's psychological division.
Stevenson's writing style even reflects this contrast. Descriptions of Jekyll's house sound "authoritative" with a pleasant rhythm, whilst the laboratory descriptions use sibilance like "certain, sinister" to create an uncomfortable, hissing atmosphere that draws readers in.
The Victorian obsession with maintaining appearances meant that a man's reputation was everything. Walking in public places, being charitable, and following strict social codes were essential. However, this pressure often led to the exact hypocrisy Jekyll represents - using respectability as a front for secret indulgences.
The foreshadowing here is brilliant. Having a house literally split in two helps readers visualise what Jekyll has done to himself psychologically. In the 1800s, the concept of split personality would have been difficult to understand, so this physical symbolism makes the abstract idea concrete.
Structural genius: The split building isn't just description - it's a visual metaphor that helps readers understand Jekyll's impossible situation.
