I'd agree not a paperweight, and the only comparable design in clear glass that I can think of is Davidson's Reg. 207909 (20.02.1893), which according to Ray Slack's book was designed specifically as a tea caddy .......... size is given as 4.5 inches in height. On that one the roof forms the lid and is detachable.
What is the size of your house Chris - is the lid separate, and does it incorporate a base? Anne may well be correct with the suggestion that yours could be for sweets.
