These days, the only sign that Banda Aceh was the epicenter of an appalling disaster are two ships carried miles inland by the giant waves. They are now popular and well-managed attractions on a "tsunami tourism" trail in the city.
There are lessons to draw from the 2004 tsunami, and from more recent and more criticized reconstruction efforts after disasters in Japan and Haiti. The Philippines also has much experience of its own recovering from typhoons and other disasters.
A full assessment of the damage caused by the typhoon has yet to be carried out. There were far more deaths in Aceh. The Philippines government said Wednesday that the typhoon killed more than 4,000 people and left 1,600 missing. But experts say the scale of the reconstruction needed in the Philippines looks broadly comparable with that in Aceh.
Like Indonesia in 2004, the Philippines has functioning national and local governments with committed, educated employees. Foreign countries are more likely to help if they can see efforts being made to spend money well.
Just under two weeks since the typhoon, saving lives and providing emergency aid are still the main focus. Corpses are still being collected from beneath the debris. But in a week or two, authorities will start transitioning into an "early recovery phase" and planning how best to rebuild the estimated 320,000 destroyed houses.
"It's never too early to start talking about it," said Nancy Lindborg, the assistant administrator of the U.S. government's aid arm. "What's very important is to move as quickly as possible, so you enable people to start thinking about the future."
Philippine Interior Minster Mar Roxas said authorities were already considering whether to put people in tents or bunkhouses. In Aceh, authorities built 24 wooden barrack-style complexes for survivors, but they were not popular, often located far from the original villages of the residents or their workplaces.
Aceh managed to build just 16,000 permanent houses in the first year after the tsunami. Spiking construction costs were one problem: Inflation hit 41 percent at one point as massive amounts of money chased limited supplies. Another complicating factor likely to be seen in the Philippines was that land titles and government records were destroyed.
"It was almost impossible," said Mangkusubroto via telephone from Jakarta. "People shouldn't have to live in tents for more than six months. It causes social tension."
It will likely take months to even decide where to build, or what safety standards to use, because the government and affected communities will need to work together to come up with the right answers. In Aceh, authorities initially banned construction close to the sea, but this was shelved as impractical because the province relies on fishing.
"We have to make sure that these buildings are not built in unsafe areas," said Nathaniel Von Einsiedel, the chairman of an urban development consultancy firm. "We don't want to commit the same mistake that may have contributed to the severity of the destruction in the first place."
The Philippine government said about $320 million in foreign aid has been pledged to the relief effort.
That's far less than the $7 billion Indonesia received after the tsunami the most generous response ever to a natural disaster but that massive amount of money created its own complications.
Some of the more than 180 aid agencies that flocked to Aceh took on projects they were not qualified for or duplicated other schemes. Some families got a house they didn't need, or in a place where didn't want to move to. Others got more than one. Today, empty, rotting houses aren't hard to find.
Another lesson from Aceh: Giving cash to disaster survivors, either in a grant or in exchange for projects such as cleaning debris, is effective and popular. Expect to see those schemes used widely in the Philippines. Old-school development thinking shied away from handing out money, partly out of fears it would be "squandered." Studies by aid agencies and academics have shown that is not the case.
Success in Aceh contrasted with stuttered reconstruction efforts in Japan following the 2011 earthquake and disaster, where more than half of the 470,000 people who either lost their homes or were evacuated from close to the Fukushima Dai-Ichi nuclear plant have yet to be permanently resettled. Ample funds have gone unspent due to legal and bureaucratic obstacles to rebuilding and shortages of construction workers.
The aftermath of the Haiti earthquake in 2010 has also been troubled. The capital is awash in new construction, but the International Organization for Migration says nearly 200,000 people are still living in makeshift settlements. The international community pledged $5.4 billion to help Haiti, but only about half has been delivered to date.
The Philippines is poor, but its governance structures are stronger than those in Haiti. Aid groups will have less money to spend than after the 2004 tsunami, but coupled with Philippine government funds and loans from agencies like the World Bank, many experts and aid workers are optimistic that the region will recover.
"I think it would be disappointing if we come back in four years' time and people are worse off than what they were coming into this," said Michael Delaney, who leads Oxfam America's humanitarian response to emergencies.
