It’s a small loft apartment I’m looking to buy. I’m looking to move where the stairs are located and have them be on the other side of the apartment so that I can extend the bedroom right on top of where they originally are. I then hope that this will also create more space for me to create 2 bathrooms upstairs as there is currently only 1. Before o purchase it I just want to make confirm how much this will roughly cost me.
PROJECT BRIEF I am planning to develop a small residential building consisting of three identical 55 sqm loft-style units. I have a clear concept and visual inspiration, but I am not a construction or architecture professional, so I am seeking expert guidance, advice, and a realistic quotation for the entire process. I have attached a full detailed project description along with inspiration images in the attachments section for your review. At this stage, I am not fully aware of all the required steps, approvals, or technical details involved in completing a project like this. Any feedback on feasibility, recommended materials, structural considerations, or necessary procedures would be greatly appreciated. My goal is to understand the total cost, the timeline, and the steps required to successfully complete this building project. I am open to professional recommendations that can help refine the design and ensure the development is safe, efficient, and achievable within a realistic budget.
Good Day Hope you're well. We live in a traditional RDP 4 room. This was built without a bathroom/ toilet inside. Please can you give me a quote on how much it would cost to add a bathroom in the house. I would ideally want the main bed to have its own bathroom ( maybe with just a shower and a second one for everyone else with a bathtub. I would like to include the tiling, all piping and installing of the tub , shower etc. I will however be buying the Bathtub , sinks , taps etc separately with your guidance and based on the plans, unless you can make recommendations of a better way. I need a recommendation of where these additions would go. It would be good if a person could enter the second bathroom without going through bedroom but not critical if its too complicated, please let me know what the easiest way is should you have done it before. I've attached a basic layout of the house and what I have in mind for the additions.
We need to build a chalet for hunting visitors. I was only provided with a simple plan and need an estimate to present to the owner. The type of material with dimensions, amount required and cost per unit will be needed. The length is 8.5m, the breadth 7.5m and from foundation to top of roof 5.5m. I roughly calculated the Bathroom to be 2.5m x 2.75m, the Bedroom 3m x 3.75m and Porch 3m x 3.75m.
