I'm usually the one who differs so here goes:- The bungalow layout isn't great. The porch on the front ( presumably a late addition ) looks fairly bad, detracts from the bungalow, prevents having a lovely entrance and more importantly blocks a direct window on bedroom 2, which has no natural light. Therefore, knock it down. This will also give you square footage allowance in hand. If you incorporate the garages into the main block of the house it allows the new bedroom space. You can build a free standing garage elsewhere on the plot, which is more than large enough, and, you already know you're not restricted to building behind the main building line. Change the garden room into a proper pitched room with insulated roof and walls, knock down the lounge wall and add bi-fold doors across the back. This now gets rid of both dated / unattractive additions. Take out the shower room and make it part of the entrance hall. The rest of the plan is pretty much self explanatory and gives you a new larger Master Bedroom with en-suite a large second bedroom and family bathroom and a further bedroom with en-suite ( for guests etc ), which used to be the main bedroom. All the plumbing should be ok, as i made use of positions already in use and back to backed the new ensuite with the old one. However, you always need to get these things checked out by a professional builder / architect,

Hi all. We just uploaded our first project on Houzz and thought it would be nice to share what we do. Please ask any questions you may have and I we hope you like it! Sunny regards.

Here's an interesting read for you, I think https://www.solarguide.co.uk/flat-roof-solar-panel-systems

When it comes to solar panels, I understand your hesitation. We had similar experiences with pushy sales tactics. What helped us was doing thorough research online and reaching out to friends or neighbors who had installed solar panels. They provided valuable insights and recommendations. Also, consider contacting reputable companies directly rather than responding to cold calls. Solar panels Ireland also has useful resources and advice for homeowners looking to make the switch.
