Totally totally normal, all newborns are nocturnal. Doesn't make it any less awful though! They sort themselves out after a few weeks and like others have said, dim the lights and noise at night but keep daytime naps in light with background noise. Temperature helps too - warmer at night and cooler in day but obviously stay within recommended safe temperature.
Tbh I didn't bother doing any of that until about 4 weeks because I just couldn't cope sitting awake in a dark bedroom all night, I "slept" on sofa with Isobel in carrycot beside me and watched tv during feeds. She only went about 15-20 mins between feeds at first so that was my coping mechanism. Do whatever helps you stay sane.
And I whole heartedly promise you - IT GETS EASIER. Faster than you probably think it will.
