If you use it sit or walk on, leave yourself a 6 foot square piece somewhere, put a chair or two on it. That's all the lawn anyone reasonably needs. If the kids want to play baseball, send 'em to local park. Cheaper on the windows. If the dog wants to run, take him to the Bark Park or run him at night when you do cuttings patrol.
Lawn is frivolous.
It is predicated on preventing HELL happening. If you've ever seen the exhausted, thin, parched soil under an old lawn, you'd know what HELL we're talking about. To prevent your neighbors sinning and driving fine SOIL to Hell pick up their green trash can's contents, compost it along with your own yard clippings. The resulting mulch will be spread thickly on your new garden. Most people have jars, cans and bottles and baskets full of seeds from last year.
