# Before You Build: How to Get Your Home Project Right > Planning a home renovation or extension? The decisions you make before building starts can have the biggest impact on your budget, your timeline and how well your home works for you. *Source: https://www.thehealthyhousepodcast.co.uk/episodes/before-you-build-how-to-get-your-home-project-right* [Open in Spotify](https://open.spotify.com/episode/0TjtiQ2BDaNgtxJoqjjq0P)[Watch on YouTube](https://www.youtube.com/watch?v=XHZ0woMnxr4)[Listen in any app](https://pod.link/aHR0cHM6Ly9hbmNob3IuZm0vcy8xMTUxNGZmNDQvcG9kY2FzdC9yc3M/episode/MzI5NTIyNjYtZDk5OS00NmJhLWE3ZDMtYzNiNzkzNTA4NTg4) ## The short version - The decisions made before a building project starts — the brief, the costs, the surveys — have the biggest impact on the eventual budget, timeline and how well the finished home actually works for the people living in it. - A good architect's job starts with questions rather than drawings: understanding how a family actually lives and challenging assumptions before committing to a design. - Before assuming an extension is the answer, it is worth exploring how much potential the existing space already has, since a better-designed layout can sometimes deliver what an addition was expected to. - Costs, structural surveys and specialist advice are best brought in at the design stage rather than after a scheme is already fixed, because problems found late are far more expensive to fix. - 3D models let homeowners see and understand a proposed space before construction begins, making it far easier to catch a problem on paper than to change it once building work is under way. - Choosing a builder is about more than price: a clear contract, regular communication and an agreed payment schedule protect both sides once a project inevitably runs into changes. - Renovating an older property calls for a fabric-first approach, improving insulation, ventilation and energy efficiency together rather than treating them as separate, later jobs. ## What this episode covers The decisions you make before a single brick is laid can matter more than anything that happens once building work starts. In episode seven of The Healthy House Podcast, host Aaron Worrall talks to architect Alexandra Powell of Powell Design & Construction about what actually separates a successful renovation or extension from one that runs over budget, overruns on time, or simply doesn’t suit the way a family lives once it’s finished. The conversation runs from the very first conversation with an architect through to moving back in, covering the brief, the costs, the builder, the build itself, and how to plan a home that still works in ten years’ time. ## Building the brief around how you live A recurring theme is that a good architect’s first job is to ask questions, not to draw. Rather than taking a homeowner’s initial idea — “we need another bedroom”, “we need a bigger kitchen” — at face value, a good architect probes into how the family actually uses their home day to day, and challenges assumptions about what the extra space needs to achieve. That process often reveals that the existing footprint has more potential than it first appears, and that a well-designed reconfiguration can deliver what an extension was expected to provide, without the cost and disruption of adding new space at all. ## Getting the process right: costs, surveys and 3D models Getting professional input early is a practical point raised repeatedly in the episode: costs, structural surveys and specialist advice are far more useful at the design stage than once a scheme is fixed, because a problem spotted on paper is a redesign, while the same problem spotted on site is a delay and an invoice. The conversation also covers 3D modelling as a way of letting homeowners actually experience a proposed space — how a room will feel, where the light will fall, how the layout will work in practice — before committing to it, rather than trying to interpret a set of flat drawings. ## Choosing the right builder and managing the build Once a design is agreed, the conversation turns to construction itself: what to look for in a builder beyond the headline price, and why a proper contract, clear communication and an agreed payment schedule matter to both sides. Changes during a build are treated as close to inevitable, and the episode talks through their knock-on effects — on cost, on programme, and on other trades — and why understanding that upfront makes a project easier to manage when something does need to change. ## Renovating an older home: a fabric-first approach For anyone working on an older property, the episode sets out a fabric-first approach — improving insulation, ventilation and energy efficiency as one connected exercise rather than three separate jobs bolted on at different times. That framing matters because upgrading one element in isolation, insulation without ventilation for example, can create new problems rather than solving the original one. ## Futureproofing your home The conversation closes on planning for change: designing a layout that still works as a family’s needs shift, rather than one that only fits the household as it is on the day building work finishes. To finish, Alexandra shares her Healthy House Checklist: assess the potential in the space you already have, think about your future needs, and take the time to get the brief right before anything else starts. ## Who should listen This episode is for anyone at the very start of a home project — whether that’s a small extension, a full renovation, or a new build — who wants to understand what the planning stage actually involves before committing to a design, a builder or a budget. ## Questions this episode answers ### What's the most important thing to get right before starting a home renovation? Getting the brief right — working out how your family actually lives and what you need the space to do — before any design work begins. Episode 7 explains that decisions made at this early stage shape your eventual budget, timeline and how well the finished home works for you. ### Do I need an architect for a home extension or renovation? Not every project needs one, but episode 7 makes the case that a good architect earns their fee by asking questions and challenging assumptions rather than just drawing what you first ask for. They can also help you weigh up whether your existing space could be reconfigured before you commit to adding more. ### When should I get cost estimates and surveys done on a building project? As early as possible, alongside the design work rather than after a scheme is already fixed. Episode 7 covers why bringing in costs, surveys and specialist advice at the right stage helps you avoid the expensive changes that come from finding problems late. ### What should I look for when choosing a builder? Beyond price, episode 7 highlights a proper contract, clear communication throughout the build and an agreed payment schedule. These protect both homeowner and builder once changes — which are almost inevitable — come up during construction. ### What does 'fabric-first' mean when renovating an older house? It means treating a building's insulation, ventilation and energy efficiency as one connected job rather than three separate ones, so improvements to each work together instead of undermining each other. Episode 7 discusses this approach specifically for older properties. ### How do I futureproof my home during a renovation? Episode 7 encourages thinking about how your family's needs might change in future — not just what you need right now — when planning layout and space during a renovation or extension. ## Go deeper [Buying a Home](https://www.thehealthyhousepodcast.co.uk/topics/buying-a-home)[Building Costs and Contracts](https://www.thehealthyhousepodcast.co.uk/topics/building-costs-and-contracts) ## Share this episode [Share on LinkedIn](https://www.linkedin.com/sharing/share-offsite/?url=https%3A%2F%2Fwww.thehealthyhousepodcast.co.uk%2Fepisodes%2Fbefore-you-build-how-to-get-your-home-project-right)[Share on WhatsApp](https://wa.me/?text=Before%20You%20Build%3A%20How%20to%20Get%20Your%20Home%20Project%20Right%20%E2%80%94%20The%20Healthy%20House%20Podcast%20https%3A%2F%2Fwww.thehealthyhousepodcast.co.uk%2Fepisodes%2Fbefore-you-build-how-to-get-your-home-project-right)[Email a link](mailto:?subject=Before%20You%20Build%3A%20How%20to%20Get%20Your%20Home%20Project%20Right%20%E2%80%94%20The%20Healthy%20House%20Podcast&body=https%3A%2F%2Fwww.thehealthyhousepodcast.co.uk%2Fepisodes%2Fbefore-you-build-how-to-get-your-home-project-right) ### Follow the show - - - - - -
