First keep what people attach to in memory and feel attached to them. These are the facade, the timber windows and the old staircases and high ceilings in a building. Other features such as services, lighting, accessibility and way-finding and the circulation areas can be changed to improve them. In general I keep items that people would take pictures of and 'improve' the things that they would complain about. 2\. When converting a shophouse into a residence, I once worked with a client who, contrary to expectation, chose to retain the airwell in the center of the shophouse instead of covering it up to add more floor area. On paper, it seemed to have cost them a few square meters but in reality, the airwell became the heart of the home, flooding the modern kitchen with natural light. Viewers of the home would be drawn to the center of the shophouse, gathering around the light-filled space to look up. There was just something so familiar and yet so fresh about the airwell that it made the most sense for this building's reuse. --- ### Save Character, Rework the Floor Plan I start by splitting two things apart. Character and friction. Character is the stuff people would actually miss if it vanished. Old brick, original trim, a solid stair rail, tall windows, the way the front of the house meets the street. Friction is everything that makes the new use awkward or flat-out unsafe. Chopped-up rooms, bad wiring, low ceilings, plumbing that's shot, an entry that doesn't work for whoever's living there now. I've been buying older New Jersey houses for 10 years, and the big mistake I see is people treating everything old like it's holy. Some of it's worth saving. Some of it is just 90 years of a bad floor plan. I've walked houses in Essex and Union County where the plaster arches were gorgeous but the kitchen was stuck in the darkest corner and the only bathroom sat somewhere that made zero sense for a modern family. Keeping those arches made the place feel familiar. Moving the kitchen and fixing the bath layout made it something you could actually live in. My test is dead simple. If a feature gives the building its identity and you can fix it for a sane number, keep it. If it kills light, safety, access, or the whole new use, rip it out and don't feel bad about it. People will forgive a ton of modern work as long as the building still holds onto one or two honest pieces of its old self. One call I was happy with was an older North Jersey house with a deep front porch and nice original woodwork by the entry. The inside needed heavy work, so the lazy move would've been to gut the whole thing flat and turn it into every other flip on the block. We didn't. The porch stayed, the entry trim stayed, the stair rail stayed. Behind all that, the floor plan got torn up. Walls came down, the mechanicals got replaced, the kitchen moved to a brighter side of the house. You'd walk up to it and from the street and the foyer it was still the same old house. But it lived like something built decades later. That balance is the whole thing. Wipe out every trace of the old building and the project feels cold. Save too much and you hand the next owner a museum that doesn't function. Good adaptive reuse keeps the parts people connect with and spends the real money where people actually live their day. --- ### Retain Historic Fabric, Add Modern Flexibility Successful adaptive reuse preserves the architectural features that give a building its identity while introducing changes that make it practical, safe, and efficient for its new purpose. I would prioritize retaining distinctive elements such as original facades, structural details, exposed brickwork, and historic materials, provided they remain safe and functional. The key is evaluating every feature against three criteria: historical significance, structural condition, and suitability for the building's future use. One particularly effective design decision is preserving an original industrial facade while modernizing the interior with flexible layouts, accessible entrances, improved lighting, and energy-efficient systems. For example, converting an old warehouse into a modern office can retain its exposed beams and brick walls while introducing adaptable workspaces and upgraded technology infrastructure. This approach maintains the building's familiar character without compromising comfort or functionality. I also recommend considering long-term maintenance and future adaptability before making permanent structural changes. The best adaptive reuse projects respect a building's history while giving it a practical and meaningful future. --- ### Select Durable Finishes, Ease Daily Care When I adapt an existing building, I start by separating features that define the building's character from elements that will create daily friction for the new use. One decision that consistently helps is choosing finishes based on how they will perform after move-in, not just how they photograph. For example, using larger format tile with fewer grout joints can modernize a space and make it easier to clean without stripping away the original look and proportions. That kind of change keeps the architecture feeling familiar while quietly supporting how people will actually use the building in its next chapter. --- ### Refresh Surfaces, Replace Damaged Materials I'm not an architect, but deciding what to keep and what to change is my daily job in interior wrapping. My rule is simple: if the problem is what a space is, change it. If it's only how it looks, keep it. In many Dubai homes the layout still works and the cabinets are still solid, and only the finish has dated. Keeping the structure and changing the surface costs a fraction of a full renovation and takes days instead of weeks. The exception is real damage like swollen MDF or water leaks, where replacing is the honest call. --- ### Assess Performance, Correct Envelope Deficiencies From a roofing and construction perspective, I begin by assessing the building's condition and the requirements of its new use. Structurally sound features that perform well do not need replacement solely due to renovation. The priority is to retain what is safe and change what is necessary for future use. The roof and building envelope require special attention. Water intrusion, poor drainage, ventilation issues, and deteriorated materials can undermine a renovation if not addressed before installing new finishes or equipment. Consider how proposed changes impact the entire building. A new use may require different demands, so decisions about insulation, ventilation, drainage, and the roof system should align with the overall renovation plan. The best approach is to preserve functional elements and address deficiencies that affect safety, durability, or performance. This avoids unnecessary replacement and ensures the building suits its new purpose. Decisions should be based on thorough inspection and project requirements, not appearance alone. --- ### Reveal Original Framework, Shape New Space Every adaptive reuse project starts with the same honest question: what does this building want to stay? That sounds almost philosophical, but after years of walking through structures people want us to transform, I've learned it's actually the most practical question you can ask. Before we draw a single line, we spend real time studying how the original builders thought where they put the light, why the ceiling heights are what they are, where the weight wants to fall. That investigation tells you more about what to keep than any preservation checklist ever will. The way I see it, a building is either a collaborator or a constraint. Our job is to make sure it becomes the former. When you fight the original structure, you end up with something that feels like a costume a new use dressed up inside an uncomfortable old shell. When you work with it, something genuinely interesting happens. The finished space carries memory and purpose at the same time. The decision I find myself coming back to most often is this: expose the bones, but change the skin. Keep the structural logic the columns, the span, the rhythm of openings because that's where a building's identity actually lives. Then let the new program breathe through it rather than over it. We did exactly this on a warehouse conversion where the client wanted a modern open workspace. The temptation was to gut it and start fresh inside. Instead, we left the original post-and-beam grid fully visible and designed around it. Every workstation, every corridor, every ceiling drop followed that existing rhythm. The result didn't feel like an office installed in a warehouse it felt like a workspace that had always been there. That distinction matters more than people realize. When a space feels familiar to the people who walk into it even people who've never been in the original building it earns trust quickly. There's continuity the body picks up on before the brain can name it. The real mistake in adaptive reuse is treating preservation and change as opposites. They're not. Preservation is what makes the change legible. Change is what makes the preservation relevant. You need both, in honest conversation, and the building itself will usually tell you where the line belongs if you're willing to actually listen to it. That's the work. Not just remodeling. Re-purposing with respect. --- ### Related Articles - 6 Strategies for Finding the Best Deals on Airline Tickets - How Do Architects Balance Preserving History With Modernizing Functionality? - How Architects Choose to Reuse or Build New on Building Projects
