Home & Room Additions
Ground-floor additions and new rooms tied into the existing house — engineered, permitted, and finished so the seam disappears.
New square footage that reads as original.
A good addition is invisible. The roofline continues, the floor height matches, the ceiling plane lines up, and the finishes carry through — so a visitor cannot tell where the old house stopped. Getting there is mostly work you never see: foundation tied correctly to the existing structure, framing and roof geometry matched, and mechanical, electrical, and plumbing extended from systems that were sized for a smaller house.
We handle the engineering and permitting coordination alongside the build, verify what the existing house can actually support before committing to a design, and sequence the tie-in so your home stays weather-tight throughout.

“We are so happy with our addition done by Unique Construction. They did a great job and on time. I especially love how detailed and clean they were. We highly recommend them.”
What Miami Owners Ask About Home & Room Additions
Specific answers for home & room additions in Miami-Dade and Broward — the questions that actually decide the scope.
What can stop an addition before design even starts?
The lot, usually. Setbacks fix how close you can build to each property line. Lot coverage and impervious-area limits cap how much of the parcel can be built or paved. An HOA or a municipal design review can sit on top of both. All of it is checkable before anyone draws a plan.
Drainage catches owners out. Adding roof and paving changes where water goes, and on a flat South Florida lot that can turn into a retention requirement nobody put in the budget.
Who hires the structural engineer on an addition, and what do they produce?
A licensed engineer is engaged for the project and produces sealed drawings and calculations covering foundation, framing, connections, and the load path from the new structure into the old one. Unique Construction coordinates with that engineer rather than performing the work, because engineering is a separate licensed profession in Florida and the seal has to be theirs.
What the engineer needs from the field is what exists, not what the original plans claimed: footing size, wall construction, and how the existing roof is framed. That verification comes before the drawings.
