Pool Houses, Cabanas and ADUs on a Lake Murray Property

Cabana, pool house or ADU?

A cabana is shade, storage and maybe a changing area. A pool house adds a bathroom, often a kitchenette, and conditioned space. An accessory dwelling unit is a complete small residence with sleeping, cooking and bathing. Each step up adds utilities, insulation requirements, permitting scope and cost. The mistake is building a cabana and deciding a year later it should have been a pool house — retrofitting plumbing and conditioning into an uninsulated shell rarely pencils out.

Utilities are the real project

Water, sewer or septic capacity, electrical service and sometimes gas all have to reach the structure. On a lake lot that often means a long trench across a sloped yard, coordinated with drainage and any planned hardscape. Septic capacity is the one that stops projects. If the existing system can't take another bathroom, that's a design constraint to know before anyone draws a floor plan.

• Confirm septic or sewer capacity early.
• Run utility trenching before finishing hardscape, not after.
• Plan the sight line from the main house — an outbuilding placed for convenience often blocks the water view.
• Match roof pitch, siding and trim to the main house so it reads as intentional.

Sizing that actually gets used

For a pool house serving a family and occasional guests, a bathroom, an outdoor shower, covered seating and real storage cover almost every use. Rooms beyond that tend to become storage. For an ADU intended for guests or family, plan the bathroom and kitchen properly and keep the living space efficient. Small buildings live large when the fixtures are full-size.

Tying it into the rest of the outdoor plan

The best versions of these projects are designed with the deck, patio and kitchen at the same time, so paths, grades and covered connections work as one composition instead of three separate builds. We design and build the whole exterior under one contract, which is mostly a way of saying nobody gets to blame the other trade for the elevation that doesn't meet.
