Room Additions That Look Like They Were Always There
You love your home. You love your neighborhood. You do not want to move. You just need more space.
A room addition solves that. But only if it is built right.
A bad addition is obvious. The roofline does not match. The siding is a slightly different shade. The floor height is off by an inch. You can see exactly where the old house ends and the new part begins. It looks like what it is: an afterthought bolted onto the side of a house.
We do not build afterthoughts.
Drome Contracting builds room additions that integrate with your existing home at every detail. We match your roofline pitch, your siding profile, your trim style, and your floor elevations. From the outside, it looks like it was always part of the house. From the inside, your home just has more room.

A small sample from a completed Drome room addition project. Exterior structure, roofline tie-ins, and finished usable space.
Pasco County is the fastest-growing county in Florida. Setback requirements vary by zoning but typical residential minimums are 7.5 feet side yard, 20 feet front yard, and 10 feet rear yard. Your addition must comply with the setbacks for your specific zoning classification. We review setbacks before we draw a single line.
Florida requires a Manual J load calculation for any HVAC system change connected to an addition. We pull all permits and have the load calculation prepared as part of the permit package.
