Balfron Tower (1967) by Ernö Goldfinger

Ernö Goldfinger, Letter 12 March 1968
Thank you for your letter of 23rd February.

I am sorry to hear that your house is so noisy. The only effective solution I can think of would be to install double glazing on all the windows. I appreciate this would be an expensive proposition. As you say, ear-plugs are a cheaper alternative.

Yours sincerely,
Ernö Goldfinger
