It's about eight-and-a-half times as heavy as a House
In other words, 1,300 tonnes is 8.33 times the weight of a House, and the weight of a House is 0.12 times that amount.(149 sq. m, single-level, unfurnished)
A 149 sq. m (1,600 sq. ft), single-story, unfurnished house (without extensive masonry) of the type commonly found in America would weigh approximately 156 tonnes, based on the weight of the included materials.

The total weight of the Statue of Liberty — the Statue's copper and framework only, excluding the base — is roughly 140 tonnes. The statue was designed using an optical trick known as "forced perspective" to make the statue appear proportionally correct when viewed from its base and is, in actuality, disproportionately large at the top.
