Example project

Home: 1990s house in Gresham, with a pool house already built beside the pool
Original request: A bar with a sink and a drinks fridge under the pool house roof
Bar: Back counter about 8 ft long with the sink and fridge, and a cedar bar counter in front with three stools
Fixtures: Bar sink and faucet, undercounter outdoor fridge, open shelves, outlets and lights
Lines: Cold water and power run out from the house, and the drain runs back to the house sewer line, all in one trench
Winter: A valve to drain the water line for the cold months
Cost: $27,500

In this example, the owners of a 1990s house in Gresham already have a pool house with a covered side facing the water. They want to make drinks and rinse glasses there instead of carrying everything out from the kitchen.

Custom enclosed pool houses

An enclosed pool house can hold a changing room, dry storage and a sheltered place to sit, all in one building. The floor plan keeps wet feet away from stored cushions and towels. Where the doors go, how much wall you can use and the path back to the house matter as much as the look outside.

Changing rooms and poolside storage

A compact changing room gives swimmers privacy without giving the whole building over to plumbing. A bench, hooks and enough clear floor make it comfortable to change. Separate storage for toys, towels and seasonal furniture keeps the room useful, and an outside storage door can make bulky things easier to move without crossing the changing area.

Pool houses with bathrooms and showers

A toilet, basin or shower by the pool can cut down on wet trips into the house. It also changes the job, because water, drains, hot water and ventilation all have to fit the layout. Pick the fixtures you want, and we will show you how the lines get there and how we handle any pool decking we have to open.

Cabanas and covered poolside lounges

A roofed cabana keeps the sides open and puts shade over your seats. It can stand on its own or share a roof with an enclosed changing room. Your chairs, a dining table and clear paths to walk set the size of the roof. The roof gives you shelter; for privacy you need walls and a closed room.

Pool house bars and serving areas

A serving counter or a window that opens can link an enclosed room to the pool deck. A dry counter is the simple choice; a sink adds water and drain lines, and a fridge needs power. We keep food storage away from pool chemicals, and we fix where the appliances go, with room around them, before we build cabinets or roof supports.

Pool houses beside existing pools

Next to a pool that is already in, we first look at what lies underground and around it. We check access for materials, the pool equipment, buried lines and the room you need to look after the pool. Point out the decking and planting you want to keep, and we will plan how to protect it, where to trench and how to put it back.

Our process

Choose the rooms and uses

First, we list the rooms you need, whether that is changing, a bathroom, storage or covered seating. Photos of the pool area, a rough size and your budget give us a starting point.

Check the property and utilities

Next we confirm who issues the permit, how much room there is and how we get in. Then we look at the spot, utility routes and grading before you pay for a finished design.

Agree on the drawings and price

Drawings and an itemized quote follow, covering the foundation, shell, finishes, utility work and putting the yard back. Before building starts, we agree who handles permits and inspections, and the timing.

Check Gresham requirements before choosing a size

Gresham's standards for accessory buildings cover where a pool house sits and how far it stands from the lot lines. Its residential building guidance covers the construction and utility work. Even a small pool house can need approvals. We find out which jurisdiction your property is in and run the rooms, height and services past the planning and permit staff before we treat a sketch as final.

What changes a pool house estimate?

Floor area is only part of the budget. A bathroom, long utility runs, hard access, foundation work and putting back paving we have to lift can change the price a lot. We list the allowances and anything left out, which makes it easy to compare prices for the same rooms and finishes. A kit price for just the shell is not the price of a finished building.

Pool houses in nearby Fairview, Troutdale and Wood Village are part of our work too. The exact address tells us whether we can cover the job and whose permit rules apply.

Frequently asked questions

Is a pool house the same as an ADU?

No. A pool house is there for the pool, not as a separate place to live. Somewhere to sleep and cook is a different matter, because Gresham regulates accessory dwellings separately from other outbuildings. If that is the plan, tell us before the design starts.

Can a pool house kit be used for the project?

A kit may supply the building shell, but the site work, foundation, putting it together and any plumbing or wiring are still separate jobs. Check which drawings and parts come with it, and have us look at whether it suits your property before you order.

Does pool house construction include the swimming pool?

No. Digging and installing a pool, resurfacing and routine pool care are separate work. When a new pool and a pool house are planned together, we agree their positions, site access and utility routes with your pool contractor before either of us settles the plans.
