Your home is your sanctuary — but if it's starting to feel cramped or the layout no longer fits the way your family lives, an addition is often the right move. Stay in the home you already love, but with the space and configuration you actually need.
Expanding the living room, adding a bedroom, opening up a kitchen, or building out a custom workspace — we plan the addition so it integrates cleanly with the rest of the home. The joinery between old and new shouldn't be the first thing visitors notice.
"How much will this cost?" is usually the first question we hear — and the most important one to answer honestly. Before construction starts, we walk you through realistic options at different budget levels so you know what each path actually delivers.
Additions involve both renovation skill (working with what's already there) and new-construction skill (building from scratch). We do both — under one license, one schedule, and one point of accountability.
Experienced Hawaii contractor — additions handled to code.
Highest material and workmanship standards across every phase.
Single project plan — trades, inspections, and finish all sequenced.
We meet on-site, look at the existing structure, and map out what's possible.
Layout, structural integration, materials, and a transparent line-item quote.
Permits, foundation, framing, mechanicals, and finish — coordinated under one plan.
Final inspection, punch list closed, and your new space ready to live in.
Cost depends on size, complexity, and how much structural work the existing home needs. After a site walkthrough, we provide a detailed line-item estimate so the budget is clear before construction starts.
Bedroom and primary suite additions, ADUs, second-story additions, lanai conversions, kitchen and living room expansions, and garage or workshop additions — among others. If it's adding square footage to an existing home, we can build it.
Timelines vary with size and scope — a single-room addition is much faster than a full second-story. Permits and inspection scheduling factor in too. We share a project timeline as part of the quote.
Yes — that's the goal. We document the existing details up front (rooflines, cladding, trim, interior finishes) so the addition reads as part of the house, not bolted on.

I worked with WQ Construction and Tommy is the manager. I am very happy and satisfied with the services. Highly recommended. I remodeled the whole kitchen and touch up bathroom, around the place and making new door for bathroom. I was amazed by their quality craftsmanship. They finished the work within the given timeframe. The best construction company that I have worked with. They are very efficient and professional.
WQ Construction did an excellent job on renovating my hallway and bathroom. Tommy was really easy to work with and he was very accommodating. All of his workers worked really hard and cleaned up daily and did a really good job at the end. I would totally recommend them for your house renovations. I would not hesitate to use them again to renovate my kitchen.
Excellent contractor completed my entire first level of the house. We removed old carpet, demolished the entire kitchen and remodeled the full bathroom. The vinyl planks are beautiful and the tile in the bathroom is perfect. We love our updated kitchen cabinets and countertops. We ended up adding recessed lighting and painted the entire downstairs with no issue with our last minute request. Our remodel finished earlier than quoted. All contractors staff are professional and always cleaned up after each job. I recommend that you consider Tommy and his company for your small or large home remodel projects.
