Your best option is still to plan before build probably with some grid papers.
Play the furniture and objects to see the grid sizes they occupy.
Say, bathtub seems only to need 2 grids, but indeed it takes a third grid right hand side grid of the tap facing the tub body for sims entry.
List out the object type's space specifications.
Draw your house plans.
Then, start to build them.
But, you can make an in-game draught/draft by just making walls and floors without decorations and landscape crafting, then place into the objects you want. Should you need testing, run a dummy family on it and probably delete this draught.
After all the preparations, start a new lot to build according to the floorplan you drew.
If you feel lost in the space, you may think about the shape and the size of the final house compared to the lot in the first place before building. Do the outline first.
If you tend to build a small room and then an another small room, then you need be capable of either remembering or drawing down the final shape and size of the house in the lot. Or, simply do some creative shapes and unsuspected change in the building style.
It's somehow really a plasticbox game... It's about knowing what piece is occupying how much space and then use something that may match to fill the space.
