Newport County will install a temporary stand to increase their stadium's capacity by 1,000 and make the most of Manchester United's FA Cup visit later this month.
The new stand will hold supporters for the match against Wrexham this weekend and their fourth-round tie against United on January 28, boosting the capacity to 9,000.
Newport beat Eastleigh 3-1 on Tuesday night to set up the dream encounter against one of football's blue-ribbon clubs.
The Exiles are likely to pocket around £400,000 from the occasion, which will be shown on BBC One.
