With full licensing and bonding, we guarantee that no project is too ambitious for our seasoned team. Trust in Wylie Construction to bring your tech-integrated dream home to life.

"We hired WPC to construct an addition our home. The project started well and we were generally happy with their work. There were several points where their oversight of subcontractor work was lacking, including a major framing mistake and roofing material that did match the rest of our house. Their invoices lacked details and upon requesting receipts and hours breakdown it was clear there were some discrepancies. For example, we were charged 8 hours for two 20 minute inspection appointments. Getting towards the end of the project it was clear that they were going to far exceed the budget our contract specified and work was very sporadic, dragging the project schedule out unnecessarily. We had a disagreement about how they were applying their margin to a new heating system in our existing home (i.e. not part of the addition), which eventually led them pulling out of the project. Had they not done that, we would have fired them due to their poor performance. We had a neighbor who hired them for a DADU project and he had a similar complaint about them not being able to deliver at the end of the project. We were lucky to find another contractor that actually showed up to do the work and did exactly what they said they would do."

Fine Design Build is a third generation, design-build company. We shepherd our clients, working side by side, with architects and engineers that we have long-standing relationships with, pushing design past traditional scope limitations. We navigate through the challenging permitting, involving shorelines development, ECA steep slope areas, wetlands. Permitting can be a huge challenge particularly on waterfront parcels. We are experts at removing obstacles and creatively designing homes with minimal to zero impact to environment. After designing your home, we shepherd you through the challenging environment of building. We are very selective about our team and in our rare circumstance as a company, the general contractor, is onsite performing a good percentage of excavation, storm water management, septic, concrete, framing and finishes. We have a unique approach with full transparency where money is spent. The customer has their foot on the gas petal/brake throughout the entire build.

"Best contractor ever. At Fine Design Build the service received was like none other, quality, craftsmanship, in both work and design. We will be forever pleased with house build that we received."

FAQs for addition to existing structure building service projects in Seattle, WA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
