"We were extremely pleased with the work they did when we had our master bathroom remodeled. The entire process was seamless from start to finish. They were so professional when they were in the house and kept the entire area contained. I always assumed a renovation would be stressful, but it was not at all. Picking out the materials and fixtures was even fun! The entire team was great and they were exactly on time to the week. They were very responsive to any questions. I highly recommend them, and hope to work with them again in the future."

We are a small architectural firm specializing in custom residential projects. We are able to help with small specific like basements, kitchens and bathrooms, but also whole-house renovations, additions and new home design. We are particularly expert historic restorations (ranging from old city homes to mid-century modern designs). Our experience also ranges to condo conversions and apartment buildings. We have many years of experience with commercial projects, ranging from tenant finish work in existing buildings to new warehouses and office buildings. Our basic attitude is "the shortest distance between two points is a straight line." With this concept we work to help our clients achieve their goals in the most direct manner possible.

Custom Home Builders questions, answered by experts

Green homes are often more expensive to build, averaging around $200 per square foot compared to the $150 per square foot you’d spend to build a standard home. However, green homes can save you money on your utility bills by consuming less energy or creating energy using solar panels or wind turbines on-site. They’re more expensive to build, but they often end up costing less in the long run.

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.

Modular homes can go up or down in value depending on a few factors. In areas where real estate is appreciating, the value of modular homes is likely to increase, and vice versa. Additionally, the value of modular homes depends partially on the area. In cities where every other home is stick-built, modular homes might be considered a functional obsolescence, in which case they could be less desirable and go down in value. In either case, though, modular homes can still be a good investment, especially since they provide housing at a lower upfront cost.

To get a quote from a builder or general contractor, contact them over the phone or online and explain your project. If you already have house plans drawn up, they’ll need to review them to determine the project's scope before providing you with a quote. Ask for your quote in writing and compare quotes from several pros before choosing the best one for your needs.

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.
