If you think it will work for you and you just need some good arguments to take to management to possibly make this happen, then consider the following...
Pandemic reaction (ie. Coronavirus, Influenza, other communicable diseases). Right now we are in the middle of a pandemic – the Coronavirus. Big companies – like Facebook, Microsoft and others are cutting their liability concerns and telling employees to start working from home. It makes sense, but not everyone can do it and you need to ensure your organization has processes in place to handle remote and virtual teams and the critical communication that must happen between and with remote employees to keep everyone working on the same page.
Most or all of my project team members are remote or not co-located. It always helps to have a history here. Have you managed any projects in the past two years where several project team members or a majority of your team was co-located with you in the same office? If so, your argument will begin to lose air. But if you have rarely – if ever – managed a project with any or even more than one or two team members were physically located where you are, then you should have a good argument for taking your project management skills to an offsite home office. Especially if you have a great track record of organized, successful project management experience and high customer experience ratings that you can show (possibly in the form of some lessons learned session notes on past projects or at least a lack of any customer complaints).
I'll take a pay cut. I know this may sound ridiculous, but if working remotely is important to you and you consider it a life-style upgrade or quality of life upgrade (which I firmly believe that it often is...it was for me), then looking at the pay differential option may work. Work through all of your costs directly associated with sitting at a desk at the company headquarters. For now, let's just consider transportation and transport time (and for purposes of this example I'll work with $90,000/year for base pay and a 30 minute drive to and from work each day using 1 gallon of gas each way):
30 minute drive to work = gas and car wear and tear and 1 hour roundtrip of your time = $5 gas and vehicle usage per day + $45/day of your time = $50/day = $13,000/year (assuming 260 work days). That's just travel time. Without taking into account any wardrobe changes and possibly eliminating a vehicle from your family's driveway meaning no insurance and licensing on that extra vehicle. But we must also consider that those items might be replaced by a higher usage of energy at your own house with you in it all day so that could be a wash. What you could do is offer a $6,000/year pay cut (about half the savings on transportation and transport time) to go remote and see how that works.
Work less, do more. This one probably needs to stay just with you because if you present it then you're employer may try to overwork you. But you likely will be able to get more done quickly from a good home office situation or even your local Starbucks (which I have found to be my absolute most productive work location). Why? Because you don't have the frequent interruptions from co-workers. Water cooler discussions are very much overrated. They often are more about backyard barbecues and gossip than real work discussions and decision making. You will likely find that you can get done in 30 hours what it took you 40 hours or more to do at the office.
My work time can be more flexible. This is a great argument if you are managing projects using project team members or interacting with project clients in timezones that are far different from yours. If you don't mind offering to be available for 11pm or 5am client calls, then this is a big plus for your argument (unless you are already expected to do this anyway). Document your argument and your regular client needs. This one also helps you argue for putting together the most accurate project status info as you can make a case for doing it the night before an important client status call after you've touched base with your project team members.
Freeing up space and resources at headquarters. This one won't be a front line argument most of the time, but there are those instances when a growing company is bulging at the seams and needs every bit of floor space. That actually was the case at one of my employers but I was already working remotely. If it works for your scenario, use it.
Summary / call for input
If you want to take your work remote, then try these arguments out on your boss. The worst he can say is “no” or “I'll consider it.” But each of these make good business sense and if you're a great employee, he should want to at least consider your interests. Good luck!
