Capturing Light in an Urban Space

natural light -elev - east This residence has recently been constructed in one of the laneways of Fortitude Valley, just outside the Brisbane CBD in Queensland. Using smart orientation and well designed glazing features, a light and airy modern house has been constructed.

This urban block with an area of about 200m², fits a house with an approximate 90m² footprint. The architect, Andrew Wiley proposed a house that is naturally lit with a spacious feel in this confined perimeter. This was done working with interior designer Benta Wiley, to maximise the effect of light play on the artworks and sculptures intended for the house. The builder, Nick Chatburn & Co, worked in conjunction with G.James Glass & Aluminium to provide the glazing for the project.

Design

There are two façades taking advantage of open areas outside to maximise views and natural sunlight entering the 3 storey building. In particular the east elevation has a glass wall the height of the building.  This wall provides naturally light to an atrium that every room in the house opens into. Glass fins support the expanse of frameless glazing. The effect of this light well gives the house a spacious feel, enhancing the flow and communication between living spaces.

Blue glass intensifies the colouration of the sky outside – used in the atrium and sliding door/windows on the north and east faces. These large windows are made from sliding doors that enable 2100 high windows.  As a safety barrier, glass balustrade is installed to the interior. This maximises the amount of light that flows into these rooms.

Shutters sit on the outside of these windows, promote a modern feel to the houses exterior.  Internally the shutters provide an insulative shade barrier, blocking the harshest rays yet letting light filter through the gaps and cooling air that flows between them. The detailing for these doors was developed at G.James – they sit on a large structural angle that is fixed to the outside of the building to give them the floating appearance.

Natural Light Features

Natural light penetrates from one side of the house to the other with the use of glass internal doors, slit windows strategically positioned to the south and west faces, and glass roof lights. There are two of these with opaque glass on the ground level that give the office and laundry a bright lift.

The third glazed sky light is a glass canopy located at the top of the stairs, leading onto the roof. An opening at the top of a space such as the atrium draws rising hot air up and out, naturally cooling the entire house and enhancing air flow through it. The glass canopy leads to a stunning outdoor area overlooking the neighbourhood, made of self cleaning glass.  Being completely see through, it doesn’t create a visual barrier in the centre of this space, but divides the different areas up for their individual uses.

Bringing the Best of the Outdoors Inside

The entire house incorporates the enjoyment of being able to make the most of the Queensland outdoors and lifestyle – starting as you enter the house.  The front door to the property is through a wide frameless glass door.  This electronically operated pivot door opens into what seems like a courtyard complete with a well planted pond. Over the pond is another frameless sliding door operated automatically, allowing lush green plant life outside to become part of the welcoming committee. This space is in fact the inside of the atrium.

Interior Inspiration

The house is an inspiration, and a beautiful example of what can be achieved with limited space in a medium density urban area.

Bushfire Risk, Assessment and Glazing Solutions

Australia has a love hate relationship with bushfires. It has been so much a part of the natural history here it has become an endemic part of existence; without bushfire certain plants wont propagate, although the rest of anything living, fears it. It’s just one of the many parts of the Australian lifestyle that needs to be taken in a serious light – and be prepared for.

Assessing Bushfire Risk

There have been major developments in ways to protect in the case of bushfire – from household escape plans, to continuing technology in fire fighting strategies and more recently since dramatic fire events, building design. Australian Standards have developed AS 3959, and as part of that, a system that determines your Bushfire Attack Level or BAL. In the BAL, it gives a provision for products in the building industry to be rated according to their resistance to bushfire attack.

The BAL rating for your situation can be determined by referring to AS3959 or guides provided by your local services. NSW Rural Fire Service has a comprehensive user guide as an Application Kit to the BAL for reference. You will attain one of six rated categories. Your risk is assessed by looking at type and proximity of vegetation, and the slope of the land your property is on. Your calculated BAL rating is used to select building products. Products will be rated with the same figures, offering protection for that level of BAL rating.

BAL Rated Glazing Options

G.James Glass & Aluminium has developed a BAL manual to guide people through making the right decision when looking at glazing products. It outlines the G.James glazing suites that should be used for buildings in the following high risk categories:

  • BAL 19
  • BAL 29
  • BAL 40

The G.James BAL manual outline the glazing system, glass type, hardware, gaskets and mesh requirements for the individual systems according to your BAL rating. As an example, if you have a rating of BAL 29, and need a double hung window, we will suggest you use the following:

The 136 Series Double Hung Window with a minimum of 5mm toughened glass, standard mohair, glazing vinyls and other hardware, and external screens require a fire retardant spline with aluminium or steel mesh with an aperture of less than 2mm. This is an example only, and you need to confirm details with G.James staff that can ensure these are the products you need for your individual situation.

Your selection of glazing should not be limited. G.James have BAL glazing solutions for sliding doors, louvres, double hung windows, fixed windows, hinged doors, bifold doors, awning windows, casement windows and sliding windows. When you talk to G.James personnel, they can guide you through the options.

Requirement for Buildings

There is no requirement to alter existing building materials, but if you plan on building or renovating, you will need to implement the recommendations of the the BAL report. It is a wise idea to be aware of the rating your property would get even if you aren’t looking at building in the near future. Finding out the weak points, you can make minor adaptions to the building materials or surrounding vegetation to give yourself a better chance in case fire ever threatens your neighbourhood.

Be aware of the different ways you can keep knowledgeable about risks in your area. Know your local brigade and SES, having their contact details on hand. Check your states fire services for more information.

During recent fire incidents when the heat was on, communication became difficult due to cut lines, and websites being bombarded and going down. The NSW Rural Fire Service had a great system of reporting regular updates on their face book feed. Know where to keep up to date on the latest details and leave emergency lines free for those that require it.

Be prepared and stay safe.

Capitol Apartments

The Capitol ApartmentsCapitol Apartments has been recently constructed at 35 Peel St, South Bank, Brisbane, QLD. It is a 10 storey building designed by Kowalski and built by TMF. This project is situated in the busy west side of South Bank, along some major traffic routes – one being Queensland Rail train tracks and rail bridge.  It is an ambitious project considering its location, and had very stringent guidelines to achieve before it was allowed to be constructed.

Strict Design Criteria

The main aspect of design took into account the proximity to the adjacent train line. Acoustics is an obvious problem, but the location of the railway tracks are within a stones throw, literally. As such, protection of the railway tracks from litter being thrown onto the lines is of critical importance. Accompanying this, the architects designed a building with many differing glazing requirements to achieve a cohesive up market residential property. This building is to be used as furnished apartments for long or short term accommodation for people in the South Bank area. With venues like Rydges and other large hotel names in the vicinity, a boutique, stylish result needed to be achieved. The Capitol Apartments The initial design phase required the windows to comply with acoustic standards, or the apartment would not get approval to be built. G.James were the only glaziers that could beat all the ratings required, and provide evidence via testing that these results were guaranteed. The design initially specified opening sizes to be built to, but to ensure quality, it was actually done as a measure and fit job. As such, the lead times were brought down dramatically in the manufacture and installation scheduling required to meet the builders time line, which G.James achieved.

Design Resolution

To accommodate the requirements to protect the tracks from litter, all windows to the railways (northern) elevation were fitted with fixed Crimsafe screens. The balconies are set up as an Alfresco area, and the Lismore designed version of the 445 sliding door system was used for the operable windows overlooking the tracks and the city, with a fixed light beneath. The Lismore design, allows the sliding door to be operated from the inside, allowing the Crimsafe screen to be fitted and fixed externally. This alfresco area also helps protect the interior from noise pollution. The Capitol Apartments Bedrooms were fitted with jockey sashes to provide an adequate acoustic barrier, and living spaces had IGUs (as well as the alfresco area) to protect it from railway traffic noise. Both use the 451 system. Some balconies also have 136 Double Hung IGUs incorporated into their design. Other areas use differing glazing suites including the 165 slider vents to wet areas, 265 awning windows, 651 shop front with IGUs in the gym on level 1 with a 476 hinged door.  The main entry was a 475 auto sliding door, and the 477-300 bi-fold system with a lowlight under in  650 framing are a suitable finish in the restaurant. All framing not done on the railway elevation used various types of SGUs to suit the look required.

Project Update – Circa Nundah

Circa Nundah

Circa Nundah is a $270 million urban renewal project from developer Property Solutions. Circa Nundah is located on a 2.5 hectare site in Nundah, Brisbane. Masterplanned by Arkhefield, the site will eventually contain three 9 storey residential buildings and an eight storey commercial building. The commercial building – Circa CT1, was completed towards the end of 2012, and work is drawing to a finish on the first residential building, Circa One.

Circa One comprises 42 one-bedroom and 42 two-bedroom apartments, 490m² of ground-level retail space, a residents’ recreation room, manager’s office and two levels of secure basement parking. Apartments generally range from 63 to 101m², with large corner garden terrace units of up to 133m². Construction on Circa Nundah Village is being carried out by Hutchinson Builders.

G.James’ Role

Circa Nundah required both G.James’ Commercial Contracting and Eagle Farm Residential Divisions to join forces to complete the scope of works.

This project called for the supply and installation of G.James’ 165 Series sliding windows, 265 Series awning windows, 445 sliding doors and 475 Series shopfront / fixed windows.

All aluminium framing was extruded and powder coated in-house and finished in Precious Pewter Pearl.

More to come

G.James have enjoyed a close working relationship with Hutchinson Builders over the course of this project. Plans for the next residential building on the site – Circa Dos, were unveiled last year, and construction is just beginning. For further information about this project or our residential solutions please contact the G.James Eagle Farm Branch on (07) 3877 2844 or via email at hilite@gjames.com.au.

5 key points for choosing windows & doors

Choosing Windows and Doors

On average, glass comprises around 25% of a home’s external surface. Along with providing light, ventilation and protection from the elements, this makes choosing the right windows and doors one of the most important decisions when building a home.

These five key points highlight some important aspects to consider when selecting the supplier of windows and doors in your new home.

Australian Window Association

Compliance & Certification

Is your window supplier an Australian Window Association (AWA) member?

The AWA Product Accreditation Program ensures that accredited members manufacture their windows and doors to exacting performance criteria.

AWA members are also required to produce windows and doors which meet the requirements of all relevant Australian Standards are subject to third party annual audits to ensure continuing compliance.

More information on the benefits of dealing with an AWA member can be found on the AWA website.

Colour Selection

Aluminium Colour Range

Choice of frame colour can be an effective tool in either complementing or contrasting your interior and/or exterior colour schemes.

Aluminium windows can be ordered in either powder coated (painted) or anodised finishes offering you a wide selection of colours. An example of typical colours available in anodized and powder coated aluminium can be found in the G.James Colour selector.

Your chosen finish must also be able to withstand exposure to the elements, so a reputable supplier will provide a guarantee against premature weathering of surface finishes.

Glass Selection

The correct glass selection can offer a number of benefits.

  • Reduced external noise.
  • Savings on heating and/or cooling costs.
  • Extending the life of soft furnishings.
  • Reducing glare.
  • Improving security.

The basic type of glass used depends on application – in areas where accidental impacts are a concern, toughened and laminated glass are much stronger and safer than regular annealed glass. Using annealed glass in areas where the extra strength is not of tangible benefit is however more economical.

Climate is another major factor in the selection of glass – in warmer climates toned or coated glass will offer performance benefits, whilst in cooler climates IGUs (double glazing) will improve heat retention.

The most suitable products for a home will vary on a number of factors, so you should speak to a professional to discuss your requirements.

Features and Benefits

Price should not be the only consideration in seletion of windows and doors – value should also be assessed in terms of the extra features and long term benefits offered by the product.

So before deciding on who will supply your windows, ask the following questions:

  • Does the window have a rigid PVC sill insert for weather performance and easy cleaning of the sill? A threshold (cover) in the door sill should also be present.
  • Are the flyscreens easily removed both internally and externally? This is an important feature, particularly for two storey homes.
  • Are window handles located in the centre? Handles located at the jamb (side) can be difficult to access behind curtains or operate when fully opened.
  • Do the window rollers contain stainless steel bearings, important for long term performance?
  • Are the window rollers of sufficient size? Smaller tyres can develop flat spots which causes the roller to skid along the track rather than roll.
  • Are the rollers height adjustable?

After Sales Service

In the event of faults with sliding windows, doors or associated hardware, you must be able to rely upon your supplier to rectify any issues.

A written warranty from a trustworthy and well established company gives you peace of mind of knowing that you won’t be left out of pocket if something does go wrong. It is necessary to read and understand your warranty agreement to know the conditions under which you are covered.

It is also important to choose a supplier who offers a stable product line with standardised features and parts across their products – you don’t want to be left with non-functional windows or doors because the supplier can no longer obtain the right parts. A supplier must also keep sufficient stock/parts on hand in order to rectify faults quickly.

Ask an Expert

Researching your window and door options will help you make an informed choice, but don’t hesitate to consult with an expert for help in selecting the ideal windows and doors.

An experienced local glazing professional will help you tailor a solution to suit both your preferences and local conditions.
