Everyone else gives you a room for the day. We give youa bed for the night.

Cherry Tree House in Rostherne, twenty minutes from Manchester, is a house rather than a venue: you train downstairs in their 1940s-Chanel-inspired studios and sleep upstairs, in a bed that is already made up.

Four made-up beds in one bedroom, dark green carpet, a folded towel set on each bed
Shared Room: A spacious four-bed room with four single beds, perfect for staying and connecting with fellow students.
A made-up double bed with green cushions, a lamp on either side and a window onto the trees
Double Room: Your own private double room, to yourself or shared with a friend, with a lamp on either side and a comfortable space to relax after a full day of training.
A corner sofa in a carpeted sitting room with a staircase running up behind it
Sitting Room: A cosy shared living space to relax, unwind and feel at home during your stay.
From £30 a night
A bed in the house, booked at the same time as your course.

    In their words

    • My whole experience with Girl Boss for the last 2 years has been the best. Becky has always been my go to girl and helped me in so many ways, she's now someone I see as a friend, along with all the girls. Girl Boss is one big family.

      Caroline WestStudent, two years

    • I've been to Girl Boss a couple of times as a model, they are excellent! The way the tutors not only teach but the lovely way they have with the students is great, so calm, patient and encouraging! The models are always made to feel at ease and confident in the students ability in performing the treatments too. I'm booked to go again soon.

      Carol BennettModel

    • I cannot believe how confident and happy I felt post my Advanced filler training with the House of GirlBoss! They looked after me, the clients were wonderful and the teaching was so knowledgable and in depth. Honestly you should have no doubts about training with these ladies because you likely won't get any better than this and I have been in the industry a long time!

      Mayling-Montana LindsayAdvanced filler training

    • I absolutely can't thank GB enough for all their hard work they put into the students. Since booking my first course last year with Tierney (I have since booked onto my levels 4, 5 & 7) I can not thank her enough for all the support she gives me, checking in on me, making sure I'm okay … it's the best decision I made joining this family.

      Louise DoyleStudent, Levels 4, 5 and 7

    • I followed GB for a while, I talked myself in and out of joining. I'm so pleased I did. The training, facilities, tutors were all amazing, best decision I made. They also constantly send up to date training and videos and they have a support group. I wouldn't hesitate to train with GB again.

    It started with £20 and two second-hand beauty beds

    A three-storey mansion at Cherry Tree House: 1940s-Chanel-inspired studios, the Cherry Tree Cafe and rooms to stay in.

    Kirsty is a mum of four and Louise is a mum of one.

    We started with £20, two second-hand beauty beds and a few bottles of skincare. People knew the odds were against us. We believed in ourselves anyway, and now we own the House of Girl Boss.

    Kirsty Deegan and Louise Timpson

    Founders and Directors, House of GirlBoss

    The people behind the House

    The two directors who built it, and the person who keeps the whole place running.

    Meet the full team
    • Kirsty

      Kirsty

      Director

      The queen of strategy, ads and finance.

      One half of the powerhouse behind the academy, with a brain that never switches off. A mum of four, autistic and ADHD, she is proof that you do not need the perfect circumstances to build an empire. She is the driving force behind every big move we make.

    • Louise

      Louise

      Director

      The creative heartbeat of the academy.

      The one who turns chaos into branding and ideas into visuals. With dyslexia, ADHD and a knack for doing things differently, she sees the world in a way most people do not, which is exactly why the academy stands out. A mum of one and the queen of design.

    • Becky

      Becky

      Company PA

      The calm in our storm, our detail-obsessed queen.

      Organised and reliable. We stole her from our own kids' nursery, and it was the best decision we ever made. Becky keeps the directors sane, the team on track and the academy running like a dream.
