It makes sense that simply planning for a smaller home when considering your self-build project will save you money, but there are further savings to be had by making smart decisions in the design and construction process, and that’s where our expertise really shows its value. This is our guide to the true cost of building a Smaller Home.
The basic maths – a smaller home is cheaper to build.
According to figures from the Build Cost Information Service, the average cost of a package home of up to 90m2 can vary between £994/m2 and £1354/m2*, depending on where in the UK you build. So even taking the best case scenario, having 10m2 of wasted space in your new self-build home could cost you nearly £10,000 that you don’t need to spend.
Now that sounds like a lot of wasted space. But when you consider that you need 0.75m2 for a standard door swing (ie the space needed for it to open), it doesn’t take many doors for that wasted space to add up. That’s why we specify pocket doors, which slide into the wall cavity and free up that space.
This is just one example of how clever design and the efficient use of space keeps the cost of building a Smaller Home down.
Our build methods are more cost-effective.
When specifying materials and suppliers for our Smaller Homes, we use products that offer an economical edge, as well as an environmental one.
Our preferred foundation system is the most efficient and cost-effective method to pour foundations and floors, drawing its origins from techniques used since the 1930s in the US and the 1970s in Scandinavia. Components are manufactured off-site and 50% less concrete is required than for a standard foundation system.
We also construct the modules that comprise our Smaller Homes off-site, allowing us greater accuracy and quality of workmanship in a controlled factory environment. These modules are then delivered to site and installed extremely quickly and efficiently, making the build process much less vulnerable to inclement weather and other typical on-site delays.
Project timescales are drastically reduced.
The benefit of manufacturing our foundation system off-site is that not only are material costs signficantly reduced, but the time needed on site is also condensed into days rather than weeks.
While it is true that a superstructure comprising SIPs initially comes in at a higher cost than a traditional timber frame system, the reduction in construction programme brings the overall spend back to a much more competitive level. A modular home of less than 100m2 can be installed in a matter of days from start to finish, compared to perhaps two weeks for a timber frame superstructure.
A shorter construction programme has a positive effect on many different areas of expenditure. Items on hire such as scaffolding, site huts, portaloos, generators are needed for a shorter period of time. Insurance costs can be minimised too, as the workforce and plant will be on site for less time.
