In Grand Designs season 17 episode 6, titled "Pembrokeshire: Low-Impact House," viewers are taken on a journey with a couple looking to build a self-sustaining, eco-friendly home on a plot of land in Wales. The couple, who are both keen gardeners, are eager to build a house that integrates into its surroundings and is as environmentally friendly as possible.

Throughout the episode, viewers watch as the couple work with architects and engineers to design a home that meets their exacting standards — a task that proves to be much more difficult than they initially anticipated. The couple wants to use as many locally-sourced materials as possible, and they also want to incorporate renewable energy sources like solar panels and a wind turbine to ensure that the home generates its own power.

As the build progresses, the couple faces numerous challenges, from inclement weather to local planning regulations. However, they remain determined to see their vision through, and viewers are given a front-row seat to watch as the home takes shape.

One of the most fascinating aspects of this episode is the way in which the architects and engineers work to ensure that the home is as low-impact as possible. The team makes extensive use of sustainable materials like natural stone and locally-harvested timber, and they also use cutting-edge insulation materials to ensure that the home is as energy-efficient as possible.

Throughout the episode, viewers learn more about the various technologies that the couple plans to incorporate into their home. For example, they plan to use a heat recovery system to capture and reuse heat generated by the home's appliances, and they also plan to install a rainwater harvesting system to reduce their reliance on mains water.

As the build comes to a close, the couple faces some unexpected hurdles, including a shortage of skilled electricians and contractors. However, they remain committed to finishing the project, and viewers are treated to a tour of the finished home once it is complete.

Overall, Grand Designs season 17 episode 6 is a fascinating look at what it takes to build an eco-friendly, low-impact home from scratch.
