Working in St. John
St. John has grown quickly, and a large share of our work here is finishing what the builder left. A generous lot, a thin layer of topsoil, sod, and nothing else. That is a better starting point than it sounds, because it means nothing has to be undone. Patio, pond or water feature, beds, drainage and conduit for future lighting can all be laid out together, then built over two or three seasons as budget allows, instead of cutting into a finished patio later to run a cable.
The catch is underneath. Construction traffic compacts Lake County clay very hard, and roots simply will not push into it. Plant straight into that subsoil with a shovelful of compost in the hole and the bed looks fine for two years, then starts thinning out — and by then the cause is invisible. Beds here get proper soil work, decompaction and amendment across the whole bed rather than hole by hole, before anything is planted.
Many St. John neighbourhoods also have HOA design standards covering things like fencing, structures and sometimes plant material or hardscape appearance. We would rather read those first than design something you then have to argue for.
Local conditions we design around
Big, open, flat lots come with their own quirks. There is little natural shelter, so wind exposure is real on new subdivisions where the trees are still small, and there is nothing to slow winter wind across a young planting. Flat ground on clay also means surface water needs a deliberate route off the property, which is why grade and downspout drainage get sorted before the decorative work rather than after. The flip side is easy machine access on most new lots, which keeps excavation and material handling efficient.
Where we usually start in St. John
On a blank builder-graded lot, the patio and the planting plan are what turn a yard into an outdoor space — and doing both to one plan costs less than doing them separately.
Hardscaping, Patios & Retaining Walls
Paver patios, walkways, fire pit areas, and segmental retaining walls on a properly compacted aggregate base — the part you cannot see is what stops a patio heaving after a freeze-thaw winter.
Paver patios typically run $15–$28 per square foot installed.
Landscape Design & Installation
Complete landscape design and installation — trees, shrubs, perennial beds, sod, mulch, and seasonal colour, chosen for Northwest Indiana's climate and your soil so the planting actually establishes.
Front-yard landscape renovations commonly run $3,000–$12,000.

St. John questions we get asked
We just moved into a new St. John build with a bare yard. What should come first?
Drainage and the master plan, before anything you can see. Work out where water leaves the property, then place the patio, any water feature, and the bed lines on paper, including sleeves for lighting or irrigation you might add later. Once that is settled, the soil work in the beds is the next priority. After those two, everything visible can be phased over a couple of seasons in whatever order suits your budget without wasting a dollar of it.
Do you work with HOA design approval in St. John?
Yes. Where a neighbourhood has design standards we ask for them at the estimate stage and design within them, and we can give you the drawings and specifications you need to submit. It is much cheaper to check first than to build something that has to be modified afterwards.
Can a koi pond go in a St. John back yard with heavy clay soil?
Yes. Clay actually gives you firm, stable excavation walls to build against. The two things it demands are attention to groundwater — clay holds water, and during a spring thaw that pressure can act on a liner from underneath if it has not been planned for — and a clear route for surface runoff so lawn chemicals and silt are not washing into the pond after every storm. Both are ordinary design work, not obstacles.
