How This Homeless Girl Turns A $100 Tiny Cabin Into A Home Warmer Than An Apartment.

How This Homeless Girl Turns A $100 Tiny Cabin Into A Home Warmer Than An Apartment.

A $100 shed and an apartment that cost her $1,400 a month, she lost the apartment. She kept the $100. That’s where Ren Callaway’s story starts. Not with a plan, not with a vision board, not with anything that looks like a choice. It starts with a number, $100, and a Facebook marketplace listing that said, “Free to whoever hauls it.”

She paid the hundred for the haul. Someone had the truck. Ren is 23 years old. She has auburn locks she wraps with strips of cut flannel, red plaid mostly, sometimes gray, and a gap between her front two teeth that shows whenever she talks about something she actually cares about, which turns out to be most things. She grew up in Portland, Oregon, not the postcard version, the east side near the rail yards where the warehouses outnumber the coffee shops and the light in winter gets thin by 3 in the afternoon, where she’s been homeless by any real definition of the word since she was 21. Not the movie version of homeless, not dramatic, not a single catastrophic moment, more like a slow leak. Her roommate situation ended. The apartment she moved into alone ate 70% of her income from her warehouse job. She held it for 8 months before the math just stopped working.

And then she was on couches, and then she was in a tent. The encampment she landed in sits on the edge of a legal camping zone the city set up two years ago. It’s not a parking lot. It’s not a church lawn. It’s a strip of gravel and dirt between a chainlink fence and a retaining wall with about 40 other people, a shared water spigot, and a porta john situation that works better in summer than in January.

She spent her first winter there in a Coleman tent rated to 40°. Portland in January gets to 27. She knows what that gap feels like. The shed came in April. She saw the listing at 6:00 in the morning, messaged immediately, and by noon, she was figuring out how to get a 7 by 8 foot prefab garden shed from a house in Gresham to a legal camping site on the east side of Portland.

It cost her $100 for the haul. A guy from the encampment had a truck and helped her break it down into panels. Three trips, 6 hours. The panels were pine over OSB, an inch and a quarter thick. They smelled like the garden it used to live in, fertilizer and wet wood and something faintly sweet.

She set it up on a flat piece of ground she’d been using for her tent. Four walls, a roof panel, a door, dirt floor, no insulation, no electrical, no heat source. In April in Portland, 38° at night, the inside of that shed was colder than the outside because it trapped ground air and had no way to release it. She slept in there the first night with three sleeping bags and woke up at 4:00 a.m. to condensation dripping from the ceiling under her face. That was day one. What happened over the next four months is the part of the story that most people don’t think is possible. Not because it requires some special skill. Not because it requires money she didn’t have. Because it requires the kind of attention to a problem that most people only develop when the problem is their actual life and they don’t have the option of calling someone else to fix it.

She started with the floor, not insulation. That came later. The floor first, because the ground in April in Oregon is cold enough to pull heat out of anything sitting on it. She got pallets, not bought, found. There are pallets behind every restaurant, supply store, and most grocery stores and half the commercial operations in any city.

And most of them are free to whoever takes them. After she laid four of them down inside the shed, too deep, covering the entire floor, that got her off the ground by 4 inches. The air gap between the pallet floor and the dirt beneath it isn’t a perfect insulator, but it changes the thermal situation enough that it’s measurable.

She measured it 11° warmer at floor level than the dirt had been. She knows this because she has a $12 digital thermometer she bought from a dollar store, two of them actually, so she could put one inside and one outside and watch the gap. The walls came next. The pine panels were doing almost nothing. They were structural, but not thermal.

She’d been keeping an eye on a Buy Nothing group for her zip code for two weeks before someone posted moving blankets. Seven of them, heavy duty, the kind movers use on furniture. She stapled them to the interior walls, 4-inch staples, the long kind, through the fabric and into the OSB. It took her two afternoons and a borrowed staple gun.

When she was done, the walls were covered floor to ceiling on three sides. The fourth side, where the door is, she left half open so the door could still swing. The ceiling was the problem she spent the longest on. Heat rises in a 7 by 8 space with a low roof. Whatever heat she generated was immediately at the top of the room and doing nothing useful, unless something kept it there.

She thought about it for almost a week before she solved it with something she’d been sleeping on. Literally, she had an emergency Mylar blanket, the kind that comes in survival kits, and she stapled it to the ceiling with the reflective side facing down. A second one overlapping the first. The Mylar reflects radiant heat back into the room instead of letting it absorb into the roof panel.

It looks like a spaceship ceiling. She likes it. By the end of April, she had a shed that was holding heat. Not a lot of heat, but holding it. The heat source itself was the hardest problem because it’s the problem with the most risk attached to it. Open flame in a wood structure with no ventilation is how fires start.

Carbon monoxide in a sealed space is how people don’t wake up. She was clear about this from the beginning. She wasn’t going to make a choice that killed her to stay warm. That ruled out most of the obvious options. No propane heaters in a sealed space. No open flame candle heaters, however many people post tutorials about them. She looked at everything.

What she settled on was a Mr. Heater Little Buddy, the small one rated for indoor use with an oxygen depletion sensor that shuts it off automatically if CO builds up, or she runs it for 90 minutes before sleep, enough to bring the interior temperature up. Then she shuts it off, and she added ventilation: a 4-inch hole near the floor on the back wall covered with mesh so bugs and mice can’t use it, which lets fresh air in while the heater runs. It’s a passive intake, not a fan.

It just exists. The heater has never tripped its safety sensor since she added the vent. She tested this for two weeks before she slept in there with the heater on. She ran it with the thermometer inside and herself outside, checking temperatures through a small gap she left in the door. She wanted to see what it did unattended before she trusted it with her life.

It raised the interior temperature by 22° in 40 minutes. Then it held there. When she shut it off and sealed the space, the temperature dropped about 3° per hour, enough that she could sleep through the night without waking up cold. The first night she ran it and slept through, actually slept fully through, no waking up at 4:00 a.m. with condensation on her face.

She laid there for a few minutes before getting up and just noted, “This works.” Then she started working on the rest. The condensation problem didn’t go away just because the temperature was better. It got worse actually, because a warmer interior against cold walls creates moisture.

She was waking up with the moving blankets damp at the edges. Damp insulation is worse than no insulation. It conducts cold instead of blocking it. So she spent three days thinking about it before she understood what she needed was an air gap between the Mylar and the blankets. She pulled the blankets off the walls, added a second layer of Mylar directly against the OSB first, then restapled the blankets on top of that with half-inch spacers made from cut pieces of wood dowels she found in a craft store’s damaged bin.

The air gap between the Mylar and the blanket is about half an inch. It’s enough. The blankets have stayed dry for eight weeks. The floor evolved. She found a rug, a real one, wool 5×7, slightly moth-eaten at one corner at a Goodwill outlet center where everything sells by the pound. She paid $4.30 for it. It covers almost the entire pallet floor.

The difference in standing on it versus the bare pallets is the difference between a floor and a surface. She knows that sounds minor. It isn’t. At 6:00 a.m. in November, standing up for the first time, she built a sleeping platform, not a bed frame. She didn’t have the materials for that, and she wasn’t going to spend money on lumber when she could think through it differently.

She stacked two more pallets on top of each other on one side of the shed, creating a raised surface 12 inches off the pallet floor. That’s her sleeping level. At 12 inches off the floor, she’s in the warmest band of air in the room. Heat stratifies, and the warmest layer is between 8 and 18 inches up when the room is warming.

She figured this out by watching where the thermometer read highest at different heights. She zip-tied it to a stick and held it at different levels. The floor was the coldest point. The ceiling was warmest, but unlivable. At 12 inches on a cold night with the heater off, it reads 4 to 6° warmer than floor level. On top of the pallets, she has a 4-inch foam camping mattress, the accordion fold kind, and two sleeping bags, one rated to 20°, one rated to 40°, layered.

She sleeps in the 20° bag with the 40° bag on top of it like a quilt. In January, with the heater running for 90 minutes before sleep and then off and the room sealed, she does not get cold in the night. She’s tracked this 47 nights since January without waking up cold. The apartment she had at 21 had forced air heat that cycled off at 2 a.m. by default, and she woke up cold twice a week.

The light situation she solved for almost nothing. She has a string of USB-charged LED fairy lights around the ceiling perimeter, $6 from a liquidation bin, and a single solar lantern that charges outside during the day. The lantern puts out enough light to read by.

The fairy lights are just for existing in the space in a way that doesn’t feel like a punishment. She put them up in May and has not taken them down. They run off a small power bank she charges at a library outlet twice a week. The power bank is the thing that most changes what’s possible. She has a 20,000 milliamp hours unit, not cheap.

She paid $34 for it refurbished, and it runs her lights, her phone, and a small USB fan she uses in summer for 3 to 4 days between charges. She charges it for free. Portland Public Library has outlets at every table and doesn’t ask questions. She’s been going there to charge it since June, and she goes twice a week, whether or not the bank is dead.

The door was originally just the panel that came with the shed, a simple plywood swing with a latch. Cold came in around all four edges. She weather-stripped it, the adhesive foam kind, $4 for a roll at a hardware store around the entire frame, and added a second interior panel she cut from leftover OSB she found in a dumpster outside a construction site.

Mounted two inches inside the first door on small hinges, the air gap between the two panels insulates better than either panel alone. She discovered this principle from reading about storm windows—two panes of glass with an air gap between them—and applied the same logic to a door. She reads a lot, the library again.

She’s been working through a section on building science, not textbooks, just whatever they have. And a lot of what she’s done in the shed she worked out from reading about how heat moves and where it goes. She says she wishes she’d known this stuff at 21 when she had an apartment, because her heating bills were $160 a month and she kept the thermostat at 66 because she couldn’t afford higher.

She thinks if she’d known then what she knows now about how heat actually works, she could have kept the apartment at 70 for the same price, maybe lower. The storage problem was something she didn’t expect to care as much about as she does when you live in a tent. Storage means a tub and a bag. When you live in a 7 by 8 room, you think you have more space, but you don’t, unless you build up instead of out.

She built shelves, not from purchased materials, from the same pallet wood she had left over from her first haul, where she pulled planks off the extra pallets, sanded the rough edges with a piece of sandpaper folded around a block of wood, and mounted them to the wall studs on the east side of the shed.

Four shelves, floor to ceiling, about 10 inches deep, where she has her clothes on two of them, folded, not hung, because hanging requires more depth than she has. She has her food on one, dry goods in sealed containers, nothing that needs refrigeration. She has her tools and supplies on the fourth. The tools are not decorative.

She has a small hammer, a handsaw, a screwdriver set, a staple gun she borrowed and eventually bought from the person she borrowed it from for $8 when he got a new one, a tape measure, and a utility knife. These things have let her fix and modify the shed in ways she couldn’t have done without them. The saw alone has paid for itself four times over.

She can cut materials to fit instead of buying things in standard sizes that don’t match the space. Refrigeration is the gap in the setup. She doesn’t have it. She gets around this by buying food in small quantities and eating it within a day, and by keeping a small cooler that she fills with ice from a gas station when she needs to. It costs about $1.50 for enough ice to keep things cold for 24 hours in summer. In winter, she puts the cooler outside. Portland in January is cold enough that outside is refrigerator temperature, sometimes colder. She’s aware this doesn’t scale. A household of more than one person couldn’t manage food storage this way. For one person eating simply, it works.

Water is the other gap. There’s a spigot at the encampment. She has two 5-gallon jugs she fills and carries. It’s heavy, but she’s made peace with heavy. She has a small hand pump filter, the kind backpackers use, that she’s never actually needed because the spigot water is municipal, but she has it because she doesn’t want to be without it if the situation changes.

She showers at a community center four blocks away that allows encampment residents access for $2 a visit. She goes three times a week. When she talks about warmth, she doesn’t mean just temperature. This is the thing that takes a while to understand from outside of it. She means the difference between a space that tells you that you’re temporary and a space that tells you that you’re not.

Her tent was a space that told her she was temporary. Every morning she woke up and the tent was there, and the tent said, “This is not a real place.” The shed is a real place. Not because it’s better built than the tent. It isn’t. Structurally, it’s better in the way a room is better than a hallway. It holds things. It holds her.

The moving blankets on the walls have a pattern. She didn’t notice this at first. Moving blankets are usually gray or brown, but one of the seven she got from the Buy Nothing group is blue, a dark slate blue with a narrow stripe, and she hung it on the wall that faces her sleeping platform. So, it’s what she sees when she wakes up.

That was not a thermal decision. She hung it there because she wanted something to look at that had color. There are small things like this throughout the shed: a photo she’s kept in her jacket pocket since before she was homeless, now taped to the shelf above her sleeping platform; a small cactus in a terracotta pot that she keeps on the window sill because the shed has a window, a small one, 12 by 16 inches on the south wall, and things grow in south light.

The cactus has been alive for 6 months. She takes that seriously. The window was the first thing she worked on after the floor. Not insulated, not sealed, it was just a single pane in the original shed kit, aluminum frame, and it was leaking cold around all four corners. She used the same weather-stripping trick as the door.

Then added a second layer of clear plastic sheeting on the interior side, held in place with magnetic tape, so she can remove it in summer. The plastic creates a dead air gap between the glass and the interior. It’s the same principle as a storm window. She can see through it clearly enough that the light quality inside the shed is the same as it would be with no covering.

She can see the sky. She talks about the sky like it matters, which it does. When you sleep in a tent, you’re in the weather. There’s no separation. Rain hits the tent. Wind moves the tent. The outside is always immediately present. But in the shed, there’s a layer between her and the weather. Not a big layer.

It’s 1 inch of composite wood, but it’s enough to make the rain sound like rain rather than feel like rain. She slept through a storm for the first time in two years last October. She woke up to the sound of it, registered that it was raining, and went back to sleep. The encampment itself is not a place most people would choose. It’s not quiet.

There are 40 people in a small space and 40 people’s worth of difficulty, conflict, illness, unpredictability, the full range of what happens when people who are all under serious pressure live next to each other with almost no privacy. She is not going to tell you it’s easy. It’s not easy. But she’s been here long enough to know who to trust and who to give space to.

And she has one neighbor, a woman named Dorene, who is 51 and has been here longer than anyone, who watches the shed when Ren goes out for long stretches and who gets watched in return. That’s the arrangement. Nothing formal, just real. The shed is hers in a way the tent never was.

She knows this doesn’t mean what it would mean to say, “My apartment,” or, “My house.” She knows she is on city-permitted land that can change its status. Or she knows the shed itself has no legal standing as a residence. She knows all of this and she still says, “Mine,” when she talks about it. Because in the absence of every conventional marker of ownership, what you’ve built with your hands and your thinking and your specific attention to how cold comes in and where heat goes, that’s yours in a way that at least what you paid someone else for never quite is. She’s not planning to stay here. She’s planning to leave. Not because the shed has failed. It hasn’t. But because it’s done what she needed it to do, which is buy her time. She’s been able to hold down consistent work since October.

Because she has a stable place to sleep, a place to keep her clothes clean, and her phone charged and herself warm enough to think straight. She’s had the same warehouse job for 7 months. She’s been putting money aside. Not fast, but it’s there. She estimates she’s about 4 months from having first and last month’s deposit saved. She’s done this math many times. She knows the vacancy rate in Portland right now. She knows what she’s going to need.

She’s not romantic about it. She’s been here before, had an apartment before, lost it. She knows what she didn’t know the first time, and she’s not repeating those patterns. She’ll find something smaller than what she had. She’ll know how to heat it without paying $160 a month to do it. What she’ll take with her when she goes: the thermometers, the power bank, the sleeping bags, the cactus, the blue moving blanket, the slate one with the stripe, the tools. What she’ll leave: the shed itself, because someone else will need it. There’s already a woman two plots over who’s been sleeping in a tent through winter and who Ren has been talking to about the pallets, the Mylar, the weather stripping.

She’s going to hand all of it over—the knowledge and the structure both. Try this: go into whatever room you sleep in tonight, turn the heat down to 45°, and sit in it for 20 minutes. Not to perform suffering, just to understand what temperature actually feels like on skin. Ren spent a winter in it, not because she wanted to, but because the options were limited.

And she picked the one that was most solvable and then solved it. She did it for $100 and seven moving blankets, and one slate blue one that she hung on the wall because she wanted something to look at that had color. The next part of her story, the part that’s coming four months out, starts the same way this one did: with a number, with a specific amount saved, and a specific thing it can buy.

With the same attention she brought to the shed brought to whatever comes next, she’s already thinking about it
