The Ark

MENTAL WELLNESS RETREAT  ·  WHITE RIVER, MPUMALANGA
THE BRIEF

A retreat for people in recovery, where every space had to support calm, dignity and clinical care without ever feeling clinical.

The difficulty in a brief like this is what you leave out. Anything that reads as a facility undoes the work the building is there to do.

A residential, hospitality-grade vocabulary carried across atrium, library, restaurant, spa, pool, art room and treatment suites — natural material, warm light and African craft, held inside an architecturally restrained envelope.

THE RESULT

A retreat that reads as a private estate rather than an institution — and a reference point for what hospitality-led wellness can be.

Jozi Gin

DISTILLERY BAR  ·  JOHANNESBURG
THE BRIEF

A striking, colourful, art-deco-inspired space for the newest Jozi Gin. The feature bar had to carry the opulence of the deco era while staying true to the eclectic industrial character of the brand — two languages that do not naturally sit together.

Resolving that tension was the project. Get it wrong in either direction and you have a themed bar or a warehouse.

ClientJozi Gin

LocationCedar Square, Johannesburg

ScopeRestaurant & bar interior design

SectorRestaurants & bars

Light industrial touches in rusted steel, and a “fan/clock” feature at the centre of the main bar carrying accent lighting that rewards a second look. The detail is where the two languages finally agree.

THE RESULT

Art-deco meets warehouse elegance — vibrant colour working against a mix of classic and modern furniture, finishes and fabrics. A bar that reads as a destination rather than a room with drinks in it.

Blue Jacket II

LUXURY YACHT  ·  KNYSNA
THE BRIEF

Classic nautical elegance meeting modern luxury, on a Knysna-built hull. A yacht interior is the hardest constraint in the business — every millimetre is spoken for, every surface moves, and nothing can be specified from a catalogue.

The brief was refinement that survives the sea: premium marine finishes, considered detail, and interiors that feel calm rather than cramped.

Joinery drawn to the millimetre and made to move — every cabinet, berth and surface built for a hull that never sits still. Warm timber against marine-grade finishes keeps it feeling like a room rather than a vessel.

THE RESULT

Refined interiors built around the spirit of adventure — a yacht that rewards long passages and looks after the people on board. Proof that the studio can work to the tightest constraints in the industry and still deliver something warm.

“Garth and Alysha were wonderful to work with. The brief was to make our boat look like a beach house, and they delivered exactly what we had in mind.”

White River Manor

LUXURY LODGE  ·  WHITE RIVER, MPUMALANGA
THE BRIEF

White River Manor is a wellness and recovery retreat in Mpumalanga — a place built for healing and renewal. The brief was to pair world-class clinical treatment with a setting calm enough that guests forget they are being treated at all.

Every decision was made to support that: rooms that encourage reflection, and a connection to the surrounding landscape that does the emotional work architecture alone cannot.

ClientWhite River Manor

LocationWhite River, Mpumalanga

ScopeArchitecture & interior design

SectorWellness & hospitality

The vision was rooted in contemporary country and farm-style architecture, infused with a distinct African flair. Earthy tones, organic textures and handcrafted detail — grounding and uplifting at once, rustic elegance carrying modern comfort.

THE RESULT

A tranquil retreat where refined aesthetics and natural elements create the conditions for recovery. Spaces encourage reflection and rest, and the connection to the landscape carries much of the emotional weight — guests arrive for treatment and stay because the place itself is restorative.

Villa Malta

PRIVATE RESIDENCE  ·  MALTA
THE BRIEF

A holiday villa with limestone walls and a view that had already done most of the work. The task was interiors that stayed out of the way of both.

Anything with a strong opinion would have competed with the building. Restraint was the whole assignment.

ClientPrivate

ScopeInterior design & detailing

SectorPrivate homes

The palette came from the stone itself — sand, bone, olive, and the greys the sea turns in winter. Texture carries the interest so that nothing has to raise its voice.

BRAND EXPERIENCE  ·  ZWARTKOPS RACEWAY
THE BRIEF

The former members’ club at Zwartkops Raceway, remade as the home of Toyota Gazoo Racing — a place to brief drivers, host guests and hold the brand’s competitive edge in one building.

It had to work as a functioning driver facility on a Tuesday and as a brand room on a race weekend.

Black and white as the ground, so the room stays sharp under low light. Colour and pattern enter sparingly — enough mischief to keep the place from taking itself seriously.
