Need cover-up nature idea for pump housing 3 feet tall in front yard

There are many great ideas for your situation. Problem is that you need an idea that fits in the landscape of your lawn. The ideas that fit your needs will make your landscape better.

Bougainvillea with a trellis would be beautiful. Easy to grow and maintain.

Does it need to be concealed on all sides? If not you could build something using trellis that is open on one side for access and grow some pretty vines. Wisteria would be pretty if it is a sunny location and if you don't mind it dying back in the winter.

Hello Ewenbugs; You could have a small pump type house built, by a handyman.

I had it done, and it did not cost much money.

Mine has a door and also a roof, for very easy access.

I would be careful with plants, as if you do need work, they can be a major nuisance!!! (I had plants around my pump house, but no more)

I hope that this will help you! Take Care.

do you need to camouflage all sides or just a couple? If just a couple, can you build a corner picket fence around it, maybe with bird house or mailbox mounted fairly high on the corner and have plantings in front and maybe a climbing vine

Since this is in your front yard I suggest that you consider a rock garden. You can put a large stone or a fountain in front of it.
