Light House ArchiScience

Light House ArchiScience Delightful, healthy, cost-effective homes — new & existing. Until 2025 we did architecture + science.

Now we only provide independent, scienced-based services and advice… the ArchiScience is the secret sauce that made our design projects so successful. The aim of the interdisciplinary team at Light House ArchiScience is to simplify the sustainable design process, to create comfortable, clever, energy-efficient homes. We specialise in energy-efficient and space-efficient homes designed to suit Canb

erra’s climate. By combining excellent design with scientific testing, we create homes that feel spacious and comfortable, and function beautifully, on a smaller than average floor area. Many of our homes achieve an energy efficiency rating of 8+ stars. Compared to a 6 star home the same size (6 stars being the current minimum standard), these houses require half as much energy per year to heat and cool them to comfortable temperatures. Our vision is to make beautiful, energy efficient housing mainstream. We hope to be a beacon for positive change in the residential construction industry. We are committed to helping people with a ‘mainstream’ budget achieve their dream of an excellent, comfortable and affordable home. Previously known as Jigsaw Housing the innovative, integrated design-science-build business restructured and rebranded in November 2015. The change has been exciting and positive; enabling a wider audience to access our unique integrated services and our collaborative network to expand.

Rarely do freshly completed Light House projects hit the market. In fact, less than 10 of the nearly 300 Light House Architecture and Science homes across Canberra have *ever* sold.

Don’t say we didn’t tell you. Smaller, smarter, sustainable, all-electric and oh so sweet: Magnolia House, 6 Carrington St, Deakin. AND it has a Hills Hoist!

Open home 12:30 today 16 August.

Note: the sale is nothing to do with us. We are just spreading the word to show people what is possible. Bigger is not better.

Six years on from the period I call “Summergeddon” in the ACT, we are distracted by so many simultaneous issues that climate change barely gets mentioned. Despite large chunks of the northern hemisphere experiencing heatwaves, droughts and wildfires like never before. Despite the world’s oceans warming faster than anyone predicted and despite El Niño already being under way for Aus and potentially reaching extreme levels.

We must continue to mitigate but we must also get serious about adapting and the industries that continue to worsen climate change must contribute to that. We can’t put our heads in the sand/smoke/under-water on this.

Please sign the petition and remind our government that we care about climate change and its impact on the natural and built environment. The climate crisis is linked to all of the other crises we are experiencing.

Climate change, housing and health were the issues that prompted me to change career in 2008. Sadly, I have not seen anywhere near the progress I had hoped to see over the last two decades.

The screen captures are from:
• a front page Washington Post article on 12 Jan 2020
• an article I wrote for magazine in May 2020

During January of 2020:
• friends (a family of four) left their Mallacoota home in the middle of the night and lived at my home in Canberra while I retreated to Lake Macquarie for some fresher air.
• my lead architect just managed to leave Corryong with her baby. Her husbands’s family lost their home. She then waited to hear if her husband and her parents could save her family home.
• one of my staff and his family with two little kids had a harrowing time stuck at Wallaga Lake.
• former staff members and good friends in Bermagui made the difficult decision to split up - he stayed to defend, she took the small kids to safety.
• I bought air purifiers for all of my staff with little kids and large air purifiers for our office.

Let’s not forget how horrible it was. Let’s prepare. The big businesses who have profited from creating this situation must pay to help us adapt to the new climate we live in.

Interesting. Now, can we get medium density working in the ACT? It wasn’t just planning changes the VIC Government implemented. Read the comments if you are interested in this stuff.
Greater Canberra

This week is getting weirder and weirder.

The Australian Financial Review (yes, that Financial Review, not the Victorian Labor fan club newsletter printed on recycled CFMEU stationery) is now running pieces arguing Sydney’s housing woes could be fixed by copying Jacinta Allan’s housing reforms.

Somewhere, a Herald Sun columnist just dropped a biro into a cup of instant coffee.

The argument is basically... Victoria’s townhouse code has made it easier to build medium-density housing (terraces, townhouses, low-rise apartments) by stopping councils from blocking everything that looks slightly more ambitious than a weatherboard shrine to 1973.

In the year since the changes came in, townhouse applications in Victoria reportedly jumped 46 per cent, reaching about 7000 in the year to March 2026.

Which is awkward.

Because for months we’ve been told Victoria is a failed state, Melbourne is basically Mad Max with trams, and Jacinta Allan cannot cross a room without personally creating a constitutional crisis or a debt black-hole.

And yet here we are, the AFR is suggesting other states might want to copy part of Allen's housing policy.

This is what serious housing policy looks like when it stops being pure theatre.

Less performative outrage.

More homes where people actually want to live.

Less “protect neighbourhood character”, which usually means preserving one cracked driveway, three agapanthus and the sacred right of a retired dentist to veto development.

More medium density.

More townhouses.

More terraces.

More low-rise apartments.

More options between “detached house 48 kilometres from work” and “vertical shoebox next to a lift shaft”.

The AFR piece also notes Melbourne has been relatively successful on housing affordability compared with other states. Again, not “affordable” in the sense that normal humans enjoy. More “less cooked than the others”, which in Australian housing policy counts as a certificate of excellence and possibly a commemorative lanyard.

The bigger point is: the ability to build medium-density housing without every council meeting becoming Lord of the Rings, matters.

NSW is going harder on high-density apartments. Victoria is leaning into townhouses and medium-density infill. Both approaches have trade-offs. High-rise can deliver more homes on one site but often needs land amalgamation, bigger capital, longer timelines and developer economics that look like a spreadsheet doing parkour. Townhouses are easier and faster to build, but use land less intensively.

The outrage economy will hate this. It wants housing reduced to villains and slogans. Greedy developers. Migrants. Woke councils. Labor. Bike lanes. An LGBTQI+ solar panel.

But the actual answer is messier and more useful: build more homes, in more places, with fewer artificial restrictions, while still protecting heritage that is genuinely heritage and not just a fibro box Bert Newton looked at once.

So yes, laugh at the absurdity.

The AFR praising a Jacinta Allan reform as a possible model for Sydney is one of those little political weather events where the sky briefly turns plaid.

But also maybe notice what it says.

Victoria did something serious on housing supply.

It did not fix everything.

It did not end the crisis.

But it moved the planning dial in a direction other states are now being told to examine.

And that is apparently enough to make the discourse short-circuit.

I’ll take raising the number who voted false from 26% to 33% as a win given the man-el (male dominated panel) was dominated by PH advocates from Sydney and I’d just hopped of a bus from Canberra in the rain. I hopped on that bus to ensure there was at least one alternative voice with significant experience with loads of homes and the people who live in them. Seems real world results down the road in Canberra count for very little in the eye of PH advocates. It was hard to get a word in which is okay cos I’m much more interested in discussions like that raised by Tone Wheeler these days. Retrofit for the win (and not to PH levels).

Our designs (hundreds of them) perform incredibly well in the harsh Canberra climate (winter minimums of -8 to summer maximums of 44). Increasing specs to achieve PH accreditation would cost at the very least 10% more for buggerall return (most of the builders we work with, who have built both PH and LH projects think more like 15%). You can still have a HRV system in a Light House if you want one — I did! I’ve written articles for Renew and Sanctuary about our approach, condensation management, airtightness and HRV that are freely available. The many builders we collaborate with can achieve airtightness levels of 2 ACH@50Pa even in renovations. That’s without an internal air barrier membrane and with just a 90mm stud frame. Back to basics: 1. Design for site and climate 2. Build it well 3. Test it works.

Although PH people dismiss our approach because it lacks independent third party verification by someone from the PH club, I can assure you we’re testing the product we design, after it’s built by a builder (independent of us) on behalf of our clients who *expect* their homes to work… and our clients stay in touch with us.

We’ve also tested quite a few Passivhaus projects. I was using a blower door and ProClima products well before PH came to Aus.

You don’t have to start a private institute and sell training and accreditation to be credible and create positive change 👩🏻‍🔬

Keep in mind that I’m not selling products, processes or even architectural services these days. What was that about independence? 😊

There are many great things that came out of the Passive House debate on Tuesday night, now doing the heated rounds on social media. But among them was the dramatic lift in knowledge about this typology that has raised the temperature of debate around the ideal building systems in this country.

Jenny Edwards of Light House ArchiScience is all about “bang for buck”. Passive House costs way too much for most people, she says, and you can get great results with the building science she brings to the industry.

Nothing excites us more than building community and sharing stuff rather than buying stuff we don’t need.

Glen didn’t need a rivet gun he needed to join two pieces of stuff together with rivets. Community Toolbox Canberra to the rescue with their brilliant BUS, busting at the seams with useful gear.

This UTTER legend is Glen 🥳

Glen borrowed a rivet gun from the Tool Bus last Wednesday evening, making him our first EVER Belco Tool Bus customer!! Glen, if we had a prize, we'd give it to you, but since we don't, we'll just give you fame. Maybe infamy 🤩

That's right, the Tool Bus now has a Belconnen stop - every Wednesday evening, between 6:30pm and 7:30pm. Find event listings right here on Facebook with all the details about when to reserve and where to find us, or read more online: https://www.communitytoolboxcbr.org/toolbus

An oldie but a goodie.

Jenny Edwards doesn't mince words on the topic of using gas in the home.

"Get off it, is my view," she tells ABC RN's Life Matters.

For a decade Ms Edwards, director and science team leader at Light House Architecture and Science, has been helping households in Canberra – most of which have gas heating, hot water and cooking – to do just that.

The effects of double-glazed windows can be mimicked with bubble wrap. Induction cooktops come with a curve for woks. Here are more tips to get energy efficient at home.
