Going to the local hardware and finding things to buy, not on the list, was a constant problem. Items such as fencing, landscaping, paint, tiling, render, tools etc. Determining extra material costsįor me, this is where blowouts occurred constantly. So if I got a 'ballpark' quote, I added 15%. Trade quoters know that if you accept a 'ballpark', an added premium when you need it done will likely be accepted. I needed quotes on a slab, roofing install, electrical, plumbing, waterproofing, plastering etc. For instance a plasterer will never give a firm quote on a house that doesn't yet exist. The trick was, staying with your original choices, when you come to purchasing. This was just a matter of visiting showrooms, making phone calls, researching on the internet and entering the values into the budgeting spreadsheet (outlined below).

These were the easily priced items on the project: land, kit home, council fees, insurance, survey, pest control, phone connection, shed, water tank, pump, fireplace, kitchen, flooring, solar, PC items (vanities, toilets, lights and fans) etc. More of a concern was dealing with the red tape of employing somebody, such as precise bookkeeping, paying long service leave, superannuation, insurance and tax.

As I was full time on the project, time wasn't so much of a concern to me. This adds more expense but reduces time considerably. This obviously is the most expensive way, but you are earning money while the build proceeds.ĭ. Beware: if a builder is building your home, they must supply guarantees. Many OBs use this system, but be careful who you choose. Lots of communication by phone as many decisions need to be done daily, as well as being on site every evening to catch up. This can only be done if you hire a tradeworker such as a carpenter/builder to do all of the work and direct other trade activities on site. Stay at work and hire out all tasks, and work on site on the weekends. Unless I hired more of the work out which would raise the build costs.Ĭ. Worrying about tradework going on at the site without supervision, not having any time off to recover each week, and lengthening the build time to 9-12 months. Working part time would have been stressfull and exhausting for me. Work part time and devote three to four days a week to the build. I did a lot of the work myself: fencing, frame erection, door and window installation, cladding, rendering, architraving and skirting, painting, landscaping.
I decided to work full time (5-6 days per week) on the project and from Development approval submission to final move in approval it took 8 months. Do I work full time on the project and get it done asap? This would require a 'gap' year, resignation, or both in my case. So my first decisions, outlined below, helped me to initially cost the project and build my budgeting spreadsheet.Ī. And lastly, creating a budgeting spreadsheetĭetermining time to be spent on the projectĪs an owner builder I need to direct all activities on site and do a great deal of the work to get this build complete.Creating a Gantt chart for project management.Determining time to be spent on the project.So to describe my budgeting techniques, here are my six parameters that assisted me. For me it was a good idea to have a contingency of 15%, although having any contingency invites overspending. I struggled to 'stick' to the budget as I'd hoped as many costs were not set in stone, ideas changed as the build progressed, and more than once tradeworkers changed, including quotes. Populating the budgeting spreadsheet for my recent kit home owner build, involved a number of systems and a lot of research and legwork.
