I have been reflecting on how we progressed the concept design on our project, what we have done well and what we could have improved on. Here are my top six:
1. Understand the Town Planning codes and the council resources
Our little patch of dirt is limited by multiple town planning codes. For Brisbane City Council, these can be found on their website.
These codes restrict what we can and can't do with our renovation project. Our project will involve raising the 90+ year old cottage about 1.5m with a new ground floor level below. At one point we had considered a design that had the front door on the ground floor along with all living space on the new level. However, the code intent is that the house should look similar to the original house with stairs leading up to a front door and patio. This enforced the idea that the living spaces should be upstairs with the benefits of better glimpses to the city and the mountains as well as the original high ceilings being extra perks of this layout.
As a result of this understanding, the three concept designs we obtained from our architect focused on living space upstairs and we didn't waste time entertaining ideas that just wouldn't make it through the town planning approval process.
2. Understand the National Construction Code (NCC)
Did you know that the NCC requires top floor bathrooms to have reinforced glass windows? In case you slip and fall into the window. Hmm. Regardless, it has to be done in order for your home to be certified. How about the distance you can build to your fence? Which your local Town Planning code may have certain restrictions, the NCC has another set of restrictions. My understanding of this is that if you build within 900mm of your boundary, you will need to install fire rated walls. Just moving your house a few millimeters could be the difference between several thousand dollars!
3. Are there any state specific laws?
Did you know that in Queensland we must have hardwired smoke alarms in all bedrooms that trigger all alarms if any one alarm detects smoke?! https://www.qld.gov.au/emergency/safety/smoke-alarms.html . We didn't. While this hasn't had a significant impact on our design, it does factor in on the cost and other states may have laws that could significantly change the way you would design your house.
4. Get inspired
You know all those magazine, Pinterest and Houzz ideas you've been saving? Make sure that you show these to your architect early on in the design process. Ideally, take them along to your first meeting with the architect to set the tone of the type of house design you are aspiring to.
We have been along to various open homes to help us get ideas about what might work for us.
Brisbane Open House Day is an event that opens up various buildings to the public to walk through, with guidance from the owner or architect. There are similar events in all capital cities.
Sustainable House Day is similar to Open House Day, except with a more environmental focus. I attended a house in a nearby suburb that not only inspired me to design our house a little smarter to mitigate energy and environmental costs, but also various unexpected ideas: a design 'theme' that carries throughout the house; and a bookshelf that continues up the side of the staircase. Our take on both of these ideas has been incorporated into our house design.
Real Estate Open Homes, including display homes. We attended several open homes to get an idea of what others have done and how it feels. Somethings just look far better, or worse, in real life. We quickly realised that the beauty of casement windows would be completely lost in our house by the desire to have security screen or flyscreens on all windows in our house. We also realised that most modern homes seem to have multiple specific living spaces: the theatre room, the family room, the rumpus room, the informal dining room, the formal lounge room... we quickly realised that our house would not have any of those things. And we're fine with it.
If permitted, take photos of things you like at the open homes and take them along to your meetings with your architect.
5. ...But don't get carried away
It should go without saying that every project needs a budget. This means making compromises.
We have made decisions on layout of our house that prioritise a large deck with a double carport below and a large open kitchen space. We see these as important spaces for how we plan on using the house. This is at the expense of our dining and living room space and the size of all of our bedroom.
How I would love to have a massive solar array on the roof, a Tesla powerwall and a multi-room audio system with speakers built into the ceilings and walls. They're not in the budget at the moment, so we will just make sure that there are suitable conduits in the walls to make retrofitting these items easy in future.
6. Have a builder provide an estimate early
As soon as you have one concept design nutted down, I highly recommend getting early engagement with a builder. Most builders will happily get involved at this stage. The estimate will be rough, but it should give you the confidence to proceed with the project with some price certainty.
Happy designing!
