The price of a room addition depends on:
Your estimate is free and itemized. Ask about home improvement financing through Slice by FNBO.
We handle the permit applications, HOA submittals and inspections for you.
In most cases, yes. Most of the work happens outside your existing walls. The messiest part is the day the opening between the old house and the new room is cut, and that area can be sealed off with temporary dust walls until the room is finished.
It can come close, but an exact match isn't guaranteed. Brick colors change over the years, and older brick is often discontinued. Options include a close blend of new brick, reusing brick removed during construction on the most visible wall, or a siding or stone accent that looks intentional.
Yes. A room addition sits on a new slab or pier foundation that's tied into your existing foundation. Houston-area clay soil swells when it's wet and shrinks when it's dry, so the new foundation has to be designed for that movement to prevent cracks where the old and new sections meet.
Usually, yes. A survey shows your lot lines, setbacks and easements, and the permit office uses it to approve the site plan. If you can't find the survey from when you bought the house, a licensed surveyor can make a new one.
Often, yes, but the new floor may need to be built higher. In a mapped flood zone, the floor of a new addition usually has to be at or above the local required flood elevation. Check your flood zone on your city's or county's flood map before you design.
The new roof is framed to tie into the existing roof, ideally at the same pitch so it looks original. Where the two roofs meet is the most common place for leaks, so that joint needs careful flashing and underlayment. New shingles may not exactly match older ones that have faded.
