Commercial office renovation and kitchenette fit-out
With Pentillion Construction, I helped coordinate a smaller commercial office renovation that included new interior walls, soundproofing review, kitchenette design and installation, glass doors and glazing, flooring, lighting, painting, and HVAC ducting.
The work was a compact tenant-improvement scope, but it still required the same kind of field coordination that makes these projects succeed. The layout, finishes, glazing, kitchenette, and building-system work all had to come together in a way that made the space feel complete and usable rather than like a collection of separate trade scopes.
One part of the work involved reviewing interior walls for soundproofing considerations. Another involved designing and installing the kitchenette so it fit the tenant’s needs and the available space. Flooring, lighting, paint, glazing, and HVAC ducting then had to be coordinated with the broader renovation sequence.
The project is a smaller example of practical tenant-improvement work: understanding what the tenant needs, coordinating the trades and finishes, and following through on the field details that turn an office renovation into a functional finished space.
Parametric espresso tools
After switching to a bottomless portafilter, I ran into two small but persistent workflow problems that did not have good off-the-shelf answers for my setup.
The first problem was cleanup. The spent espresso puck would not always come out cleanly, even with a knock box. I designed a flexible TPU ejector that seals against the bottom of the portafilter basket. A quick smack creates enough air pressure to push the grounds out cleanly into the compost.
The second problem was fit. I wanted a tamping station that actually matched my portafilter, but many printable holders online describe compatibility by brand or general size without exposing the dimensions that matter. In practice, the fit depends on details like basket diameter, ear geometry, handle angle, saddle height, and counter clearance.
To make the design more adaptable, I created a parametric OpenSCAD tamper station. Instead of remodelling the holder for every variation, the key dimensions can be measured, entered, and regenerated for a specific portafilter setup.
This is a small project, but it captures a useful design pattern: solve the immediate problem, identify which dimensions actually control fit and function, and turn the solution into something adjustable enough to be reused instead of rebuilt from scratch.
Fridge door closing magnet
My fridge door would sometimes stop just short of closing fully. It was a small problem, but the result was annoying: the door could look almost closed while the seal had not fully taken over.
I considered a few possible fixes, including tipping the fridge back slightly, adding an alarm, or designing a retracting magnet mechanism. Those options would have added complexity or solved the problem after it happened rather than helping the door close properly in the first place.
The simpler answer came from looking more carefully at the fridge itself. I noticed an unused feature from the reversible-door design: a spot where the door hardware could have been mounted if the hinge direction were changed. That gave me a clean place to attach a small helper without modifying the main door or cabinet.
I designed and 3D printed a small holder for rare earth magnets. The magnets provide just enough pull to bring the door through the last bit of travel so the edge gasket can take over and seal the door normally.
It is a small project, but it captures a useful design pattern: look at the actual object, notice the features that are already available, and choose the simplest physical intervention that solves the real failure mode.
Fridge circulation fan
My Danby all-fridge was freezing food on the lower shelf while the rest of the cabinet stayed at a normal temperature. The drain was clear, and the fridge appeared to be operating normally, so the problem was not obvious from a standard check.
I used a thermal camera to look at what was actually happening inside the cabinet. The images showed cold air pooling near the lower back of the fridge. The unit relied mostly on natural convection rather than a built-in circulation fan, so the coldest air was not mixing evenly through the cabinet.
The fix was a small targeted airflow improvement rather than a major appliance modification. I added a low-voltage fan on a custom 3D-printed bracket to gently circulate air through the cabinet. I also added a small thermal switch attached to the compressor so the fan only runs when the fridge is actively cooling.
The result was a more even temperature distribution and a practical fix for a frustrating problem. It is a small project, but it shows a useful pattern: diagnose the actual system behaviour, avoid unnecessary complexity, and make a targeted physical improvement that matches the real failure mode.
And now I have no excuse not to eat my vegetables.
