Hi,
Try in the following way
 

public with sharing class LongProjectOrderController  {
    public String MasterRecordId        {  get; set;  }
  
    public Project__c ChildRecords   { get; set;   }
   
    public LongProjectOrderController() {
	
	 List<Project__c> lstProject = new List<Project__c>();
	 
         MasterRecordId =ApexPages.currentPage().getParameters().get('id');
	 
	  lstProject = [SELECT     Name,CreatedBy.Name,Room1_Payment_Include_In_Print__c,Room2_Payment_Include_In_Print__c
					 FROM Project__c
					WHERE Long_Project_Order__c = :MasterRecordId];
	 
	 ChildRecords = (!lstProject.isEmpty()) ? lstProject[0] : new Project__c();
    }
}
