Morebrook Textiles hopes to demolish a number of buildings at the March Street Mill in Peebles to make way for a residential development.
Public exhibitions of the proposals took place last year.
The company has now submitted more detailed plans of the buildings it hopes to demolish and retain across the site.

Julie Wadsworth, 60, told officers "a fumble" had led to masturbation but she had "no reason to believe he was under-age", Warwick Crown Court heard.
In a transcript read in court, she said she had "sex in the woods" with husband Tony to "spice up" their sex life.
The couple deny assaulting seven boys in the 1990s.
The Wadsworths, from Broughton Astley, Leicestershire, who have worked for BBC Radio Leicester and BBC WM, are accused of encouraging boys to take part in sexual activity in wooded areas of Warwickshire between 1992 and 1996. They deny five counts of outraging public decency.
Mrs Wadsworth has pleaded not guilty to 12 charges of indecent assault and Mr Wadsworth, 69, denies 10 counts of the same offence.
After her arrest, Mrs Wadsworth described sexual contact with one of the accusers, now in his 30s, as "just a bit of fun", the jury heard.
She said it ended when her husband became suspicious and both parties "decided it ought to stop".
Mrs Wadsworth told officers she would never sunbathe topless, as was alleged, as she was "not confident in my body" but did sometimes have sex in woodland with her husband.
"We'd nip into the woods and if we heard anybody coming we'd stop - we wouldn't openly display ourselves," she said.
"We just went down and had sex in the woods from time to time, it's so embarrassing.
"We like to spice up the sex life, but those boys? I don't recognise any of their names."
Earlier, the man Mrs Wadsworth accepted masturbating told the court he sent messages to her years after the alleged abuse.
He said in cross-examination by her barrister he had become "obsessed" with her and sent her messages when he was "drunk, depressed, or down".
The trial was adjourned until Wednesday.

Myles Bradbury has lodged an appeal against a 22-year jail sentence imposed last December.
He admitted abusing 18 children at Addenbrooke's in Cambridge between 2009 and 2013.
The mother of the 11-year-old abused when he was kept on as a patient told the BBC Bradbury should never be freed.
Bradbury, 41, from Herringswell in Suffolk, was jailed at Cambridge Crown Court for sexual assault, voyeurism and possessing more than 16,000 indecent images.
The court heard the images of his victims were taken in the hospital.
Victims told investigators Bradbury had focused on examining their private parts when there was no medical need to do so.
The child, who is now 13, was referred to Bradbury because his older sister had a blood disorder and it was feared he might have the same condition.
But, his mother said, there was nothing wrong with him.
Instead of discharging him from his patient list, Bradbury continued seeing and abusing the boy for a year.
The boy is currently on heavy medication to deal with the mental effects of his abuse.
His mother said she did not know how Bradbury could appeal.
She said: "He is in prison now, probably doing his crafts or whatever. We are suffering every day.
"He does not understand the knock-on effect he has had on families."
Bradbury's appeal will be heard at the Royal Courts of Justice on 12 June.
Planning permission in principle is being sought to redevelop the site of a former Borders textile mill.
