Local construction knowledge
General Contractor in Potomac, MD
Potomac projects often have more land than closer-in neighborhoods, but larger lots do not eliminate site constraints. Long utility runs, sloped drives, retaining conditions, stormwater, tree cover and private well or septic systems can be central to feasibility and cost.

Large additions and custom homes benefit from early coordination between architecture, structure, civil/site work and building systems. Dena House brings construction and engineering review into the process before a refined plan is assumed to fit the site budget.
Approvals
DPS, land development, wells and septic systems
Montgomery County DPS handles residential building review, while land-development requirements can involve stormwater, sediment control, floodplain, right-of-way, tree and drainage work. The exact package depends on disturbance, grading and site conditions.
For a property served by well and septic, added habitable space must be evaluated against septic capacity and reserve-area setbacks. The county guidance notes that proposals increasing habitable space require review before building-permit approval. That analysis belongs near the start of addition planning, not after the floor plan is complete.

Existing conditions
Large homes and long-term systems planning
Potomac includes mid-century houses, large traditional homes and newer custom construction. A major renovation may need to address broad roof areas, complex HVAC zoning, long plumbing runs and exterior drainage while the interiors are reconfigured.
On expansive projects, equipment access and future service matter. Mechanical rooms, panels, pumps, controls and exterior systems should be organized so a technician can reach them without opening finished ceilings or moving built-ins years later.
Conditions to plan around
- Septic capacity and reserve-area setbacks
- Stormwater and sediment-control scope
- Long utility and driveway access
- Mechanical zoning and equipment service space
