This doesn’t help with Mrs Coleman but for background: I found the almshouses on the Valuation Survey of ~1910.
The site is described as "5 Almshouses, garden & prems."
Occupiers: Various
Owner: The Lord of the Manor, Capt J. B. Gilliat, Chorleywood Cedars
Interest of the Owner: Manorial Right to appoint the tenants.
"no rent is paid by the tenants"
The description states:
"5 old Cottages in High St in gd position
Accom,
Gd. Fl. no passage. Sitting rm f [fair?] & small bedrm f.
Outside Cor[rugated?] Iron shelter & 2 w.c's.
Very old built 1682 & now in on f. sound condition."
Valuation
"The whole value is in the site, the bdgs are only fit to be pulled down."
The site was valued at £357, then overall was rounded up to £460 to include a notional £103 for the structures [salvageable material?]
