Urban Sea House, built in 2025 and situated in the prestigious enclave of Balmoral in Mosman, New South Wales, is a residence that balances quiet elegance with thoughtful artistry. Designed for international clients, Daniel Boddam and Simone Haag created a retreat that captures the serenity of the coast while reflecting metropolitan sophistication. Every corner reflects a careful choreography of light, material, and form, inviting residents to unwind, linger, and take in the serenity of the coastline.
Two visionary creatives, Daniel Boddam and Simone Haag, collaborated for this project. Boddam, whose studio has been shaping architecture since 2013, believes that wellbeing is embedded in the spaces we inhabit. His work blends sculptural form, spatial harmony, and careful craftsmanship, creating homes that feel calm and considered. Haag, leader of an award-winning interior decorating studio, complements Boddam’s approach with an eye for furniture, lighting, and art, crafting interiors that are refined, layered, and deeply personal. Together, Boddam and Haag elevate Urban Sea House into a home where every detail, from the clever architecture to the stone texture, feels intentional and creates a calming atmosphere.
The residence itself rises from a sandstone base, characteristic of the Balmoral shoreline, with a stepped façade leading to terraced gardens. A white-rendered mid-section with soft, Mediterranean-inspired curves contrasts with a minimalist black timber pavilion above, a quiet lookout framing the harbour while being shielded from the street. Inside, a curved stucco wall draws visitors into the soaring entry hall, where a suspended sculpture encourages guests to pause for a moment before ascending the staircase. Materials are considered with care: travertine, oak, brass, and soft plaster create depth and texture.

The master suite looks out over the stunning harbour, with a curved oak bed and a travertine bath that are inspired by the shapes of sand dunes. Guest rooms open to private courtyards with Japanese-style gardens, where gentle water features provide a calming soundtrack. The living areas are raised to make the most of the light and the views, with a travertine and brass kitchen island sitting at the heart of the space. Outside, the black timber lookout and limed oak beams frame the pool and the harbour, blending interior and landscape into one space.
Urban Sea House is a home filled with contrasts: between city and coast, and light and shadow. Yet, it still feels perfectly balanced. Through the thoughtful use of certain materials, careful details, and sculptural finishing touches, it becomes a haven that celebrates both the natural beauty of its surroundings and the effort that went into every corner.
