You can always sell a building then buy it back and level it  back up. Like u can have 2 Pagan Halls. If you Achieve Max Level 10, or any level and sell it. If you gold is already full,  it will ask,  do you want to still sell it and lose that gold, just select yes. Now u are entitled to 2 pagan halls even if u sell  it,  that 1 pagan hall will go back to the shop and u can buy it again. You buy it and spend the excess resources on leveling it up again. That way, you  dont stop gaining experience and you need that to level up. I constantly sell and buy back Stonehedge and the Saloons. Those two buildings alter how long u have to wait and to me, thats not important so i use those two. You can also sell and buy back 1 of your Parliment buildings. That way you spend more on your cards, plus you spend resources leveling up the building
