A Detailed Account Of A Modern Upper Floor Extension To An Art Deco Maisonette

Our clients had a specific idea of what they wanted to achieve when they contacted Supa Group.

With two young teenagers, this 1930’s Art Deco Maisonette was seriously needing more space. The obvious solution was an upper floor extension allowing the clients to retain their beautifully landscaped garden whilst providing much needed space for their growing family.

Inspiration for this upper floor extension came from a ski trip to New Zealand where the clients stayed in a lodge that boasted an ultra-modern façade.

Part of the brief was to create a strong yet defined connection between the ground and new second storey addition rather than build a pastiche of existing. The new addition not only had to work well with the existing Art Deco features, but also have a modern look through design, layout and choice of materials. The aspiration was to create a visually striking and modern extension showcasing the use of natural and modern materials, fulfilling the client’s requirements within budget

The Scope of Work involved an upper floor addition with an alteration to the existing study so as to create room for the staircase, minimising the impact to the existing floorplan, whilst maintaining the architectural heritage of the home. The upper floor addition comprised of two bedrooms with built in robes for the client’s teenage children, serviced by a main bathroom and powder room. A store room and living area were also included.

In order to create better connectivity on the ground floor, some minor structural changes were also required. A wall between the staircase and dining room was removed to ‘open up’ and create a better flow between rooms.

As a Design and Build company, the goal to achieving design excellence in the field came through strong in house and on site management and teamwork. It was imperative that the transition from the drawing board to construction ran smoothly ensuing that the project met and exceeded client’s expectations without build delays or increased costs.

Strategic planning, concept development and regular communication with the client allowed for proficient detailing of the design and guaranteed works were executed with professionalism and finesse.

Being able to see and experience the design in 3D during Concept stage provided the clients with immeasurable reassurance and confidence on how the design was going to look and work.

Extensive research and sourcing the right products, materials and colours during this stage provided clarity and transparency on achieving the right balance between the client’s quality expectations and final completed results.

Nestled proudly on the Maisonette, the new addition was visually striking. Black ash stained Western red cedar was used on the façade, the timber bringing a natural raw yet warm element to the structure. This versatile yet renewable product married beautifully with the built up chimney clad with ‘Unique Metal’ double lock standing seam. The last dimension, adding depth and texture was the extruded windows with larger casings in matching cladding.

To make the upper floor extension more cost effective, James Hardie Scyon Axon cladding was used to the sides and rear of the second storey extension, being less obvious from the street view.

Encasing the whole structure was the Colorbond metal deck roofing and attention to detail was not overlooked with the Colorbond fascia, gutters and downpipes to match, bringing cohesion to all elements.

Internally, quality was not compromised. Square set cornices replaced semi fancy from the dining area onwards, the simplicity and clean look requiring precision workmanship. This feature continued throughout the new first floor addition. Going up, the staircase with its timber top balustrade and shadow line detail opened up to the living area with dark stained Tasmanian Oak floorboards to match existing.

The bathroom was adorned with high quality fittings and fixtures with a free standing bath from ACS Designer bathrooms taking centre stage. Against the cool palette of charcoal and off white floor to ceiling porcelain tiles, stone benchtop and timber cabinetry added warmth and texture with chrome tapware.

No project is without its obstacles and in this instance the Maisonette was located on a narrow block. The design had to ensure that the setbacks and overshadowing criteria was met and that the unashamedly modern extension did not overpower the classic Art Deco home but made a virtue of the contrast.

Having technically sound, completely coordinated and detailed set of documents and plans and constant communication between the Builder and client, ensured a clear path to a successful execution of design in the field.

We always strive to provide customers with the best in sustainability and innovation that is suitable to their project and budget.

This house feature R2.5 batts external wall insulation and R5.0 batts ceiling insulation to all the existing ceilings and proposed ceilings. This involved removing the existing “blow in” insulation to the existing dwelling. R2.0 Sound screen batts were installed between the Ground and First floors to decrease noise.

Clear double glazed Low ‘E’ glazing was used to reduce the UV rays and reflect heat while allowing sunlight to enter the home, keeping the home warm in the winter and cool in the summer.

The mix of Western Red Cedar & James Hardie Axon Cladding with Cutek CD50 Black ash staining gave the house the ultra-modern look the owners were seeking. Complimented by applying the same finish to the entire external first floor allowed the viewers eyes to drift seamlessly throughout the subtle lines of projected window architraves and the distinct modern low pitched roof.
