Mike Hartnig

Design & Construction

For Mike Hartnig, inspiration can come from the most unlikely of sources, but as a self-confessed ‘scavenger’, his knack for finding unique things and repurposing them to suit a client’s needs are exactly what makes him sought after.
Having worked in design and construction for many years, Mike’s career has taken him many places, including designing and manufacturing furniture for the interiors of prestigious resorts, including Peppers Hotels and Resorts, Oaks Hotels, Meriton and Mantra Group.
Mike has worked on projects both great and small and is perfectly placed to meet your design needs.


Settling in the Blue Mountains and opening Blue Mountains Interiors with his wife Mandy in 2012 and subsequently co-founding Thornton & Blake with Mandy and Anne Hogarth gives Mike the opportunity to focus his energy on product design and placement, designing and manufacturing fireplaces, furniture and also finessing architectural layout.
Perhaps one of Mike’s greatest achievements was when a customer came to him with a pile of old wood – the remains of an old shed and timber fence – and asked him to turn it into a kitchen. Never one to shy away from a challenge, Mike went about turning it into an incredibly quirky, functional and inspiring space, reminiscent of old fruit boxes inside timber frames, complete with an old-fashioned plate rack across a window, making the most of the light to highlight an antique dinner set.
Whether you’re wanting a full makeover or a few tweaks, Mike will be able to turn your vision into a reality.


Mandy Hartnig

Interior design & décor

Mandy Hartnig has worked in the interiors industry for over 25 years, both in the UK and in Australia. She co-founded Thornton & Blake in the Blue Mountains with partner Mike and interior designer Anne Hogarth. Mandy loves assisting clients to define their special space, their sanctuary if you like and it’s definitely all about the journey and making good friendships along the way.

Mandy’s special skillset and passion is to inspire people with creating a home that truly represents the way they want to live.


Before moving to the Blue Mountains, Mandy spent 10 years working in Sydney, honing her skills & creativity and working alongside great designers, architects and manufacturers. A proud achievement was as partner with the Peppers Hotel Group.
Mandy acted as Designer and Project Manager for many hotel and resort groups, developing, and refurbishing 5-star hotels. This role included total room fit out of up to 300 rooms per project, sourcing everything from furniture, bath towels… even the teaspoons!
Today, Mandy’s passion is product and business development, she is inspired and driven to source the best, the beautiful and the bespoke – basically anything that makes people go, “wow”!
If Mandy were to describe what makes her tick, it is being in the moment, working with like-minded, creative people, and transforming people’s homes. She would say the kitchen is the heart of the home, where family and friends gather to enjoy each other’s company and talk about food – another passion of hers. This is why she loves selling Esse cookers and demonstrating their capabilities. This feeling of coming together is probably why she also has a distaste for colourbond fences, the absolute pits of today’s home design with prison-like surrounds that she believes creates a division between people and community spirit.
When not busy working on exciting design projects, Mandy finds solace in nature, especially feeding three pet magpies at the studio where she loves to sit, feed and watch their antics. And of course, we can’t forget the beloved pet poodle “shop dog” Freddie, who loves to greet customers with a smile and a wagging tail!


Anne Hogarth

Interior design & soft furnishings

A few years ago, Anne Hogarth had a significant birthday and decided the time was right to change careers to something she truly loved. That’s how she wound up trading in her corporate job and enrolling at the prestigious Sydney Design School where she graduated with a Diploma in Interior Design and Decoration.

A co-founder of Thornton & Blake, Anne is a talented interior designer and decorator, specialising in soft furnishings, window treatments and space planning. Anne aims to balance aesthetics, form and function to produce designs that are not only beautiful to the client, but are also environmentally friendly, low energy, functional and space efficient.


Living and working in the Blue Mountains provides Anne with access to many highly talented local artisans including ceramicists, painters, weavers, glass blowers and lighting specialists, and the one-off pieces they produce feature in her interiors.
Anne translates her clients’ need into interiors that are tailored just for them. Her intuitive sense of colour and textiles creates a grounding elegance that characterises her work.
Combining the classic and contemporary, fine antiques and market treasures, she crafts warm, inviting spaces to be lived in and enjoyed, not simply looked at and admired.
Aside from the look of painted brick, Anne loves her two cats, Daphne & Niles (named after the characters in the comedy series Frasier) and food, so much so that her stomach often determines her travel itineraries with restaurants being booked before accommodation!


Ellisha Gronlund

Colour design & finishes

When it comes to paint – both the product itself and its technical aspects – you’d be hard pressed to find someone more knowledgeable than Ellisha.  Having spent the last 15 years working with paint, Ellisha has been called ‘The Paint Guru’ on more than one occasion! Ellisha loves mixing paints and custom eye matching to create unique colours, perfect for your project. Besides paint, Ellisha’s other area of expertise is fireplaces. Her deep product knowledge means she can easily help you identify a fireplace that will suit your home, budget and keep you warm on those chilly Mountain nights.


Jess Hassen

Design assistant

In 2014, Jess studied interior design at the Commercial Arts Training College CATC where she not only gained invaluable design skills, but also an understanding of how to create stunning, yet practical spaces. Known for her creativity and ability to come up with effective design solutions for any sized-project, Jess has a knack for leaving her customers with a happy smile on their face and feeling inspired thanks to 10 years’ of customer service experience.
