Brief & Context:
A 480sqm block with a 11.7m width creates design and planning policy challenges, of which led to the southern wall of the open plan living being built on the boundary (a variation to planning policy was negotiated through council). Creating light filled spaces from a southern facade is always a challenge with inner city blocks, not to mention building on boundary and ensuring privacy for all.

A very simple plan extends from the original home, retaining 2 large bedrooms, ensuite, bath and a multi room, allowing flexibility for play, tv, learning or a 4th bed room. An obscure glazed door to the central hallway creates the transition point from old to new. Upon entering the new open plan lobby you are introduced to the open plan living. A laundry on the southern side and a study on the northern side. The open plan Kitchen living and dining area overlooks the garden and alfresco. A large glazed stacking wall opens up the living area to the exterior, essentially creating external rooms. A master bed and ensuite overlooks the garden and pool to the western end. A double garage is accessed from the western laneway. The landscaped garden is finished with a combination of low level planting, ornamental pear trees and star jasmine climbers to create a green wall.

Design Response & Description:
The design responded to the brief by creating an open plan living to take advantage of the northern orientation, creating a light filled living area.
As the primary natural light was supplied from the northern glazed wall, a number of skylights were introduced along the southern boundary to balance the light within the space.  A feature sklylight was introduced above the kitchen island / seating & a bench top window naturally illuminates the workbench overlooking a landscaped garden, to further increase the sense of depth + space.The simple non complicated plan allowed for the layering of details and materials to bring the addition to life. Floors are finished with Seville Silver Limestone, Kitchen island + bench top in Silba Grey Marble. Rich dark brown Bottega oak cabinetry adds to the luxury finishes. The southern wall of the open plan illuminated by the high level skylights, along with roof overhang to the north allows indirect natural light, eliminating glare on the occupants. The recessed battens create both additional height, layering of materials & also the opportunity to conceal all non-essential ceiling fixtures; concealing the ac supply & return ducts allowing for a clean crisp white ceiling to open plan living area.

The simple plan overlooking the garden & pool with natural finishing’s & light filled open space creates an instant sense of calm. The space has its own unique get away feel.

Seamus provided design, council approval and build support for our home in Mount Hawthorn over the period 2018 to 2020. Several concept planning designs based on our initial guidance were delivered along with practical design advice in accordance with the project brief and budget. The interior design and colour pallet selection process was simple and professionally managed to ensure a quality product. Seamus provided support throughout council approval, including engagement with neighbours for an outcome that satisfied all parties.

The design outcome is in alignment with the initial scope, entirely functional as a family home and utilises the block to its full potential. The addition is full of light and free flowing to the alfresco area, where we spend a lot of time. There is a seamless transition from the retained character of the Federation front of the home to the modern addition. The support provided through the design, approval and construction cannot be faulted and we have no hesitation in providing a reference for Seamus Ryan Architects for future clients.
