Mr Gandapur's party backs talks with the Pakistani Taliban
Mr Gandapur's party governs Khyber Pakhtunkhwa, a militant stronghold, and backs talks with the militants.
There was no immediate claim of responsibility for the attack.
Last week the Pakistani Taliban leader told the BBC he was "open to talks" but would continue to target the US and its allies.
Mr Gandapur is the most senior member of former cricket star Imran Khan's Pakistan Tehreek-e-Insaf party (PTI) to be killed in a wave of attacks which have left hundreds of people dead in recent months.
The Associated Press, quoting senior police officer Mohammad Jan, reports that the bomber killed the guard at Mr Gandapur's residence before blowing himself up inside the guest room.
Mr Gandapur was taken to hospital in a critical condition but died on the way, he said.
"I saw so many dead people and injured people crying for help," said eyewitness Haseeb Khan, Reuters news agency reports.
Police have said that they fear casualty figures could rise.
