Two-story additions, second story additions, split-level extensions, and in-law additions are the most common projects homeowners pursue today. If you don’t want to go through the time consuming process of buying a bigger home, going with the addition route allows many more options. These options include adding an extra dimension to their current home, improve the livability of the space, and bringing a much-needed change to the overall style of the home.

Two story additions

If your house already has two levels, but needs extra length or width on any side, a two-story addition is a great way to add plenty of space as well as increase your property value.

We clean our messes as they happen and drastically reduce the impact of construction on your everyday life

Our team has experience with all types of additions, which means we can walk you through the process with ease. A two-story addition is a major project that requires excavation, installing new foundation slab, upgrading electrical and plumbing, and a good amount of construction mess. However, we clean our messes as they happen and do everything we can to drastically reduce the impact that your construction project has on your everyday life. We have absolutely no intention to leave you every night living in a mess of construction dirt and dust.

Second story extensions

Adding a second story to a home allows homeowners to capture better views and maximize square footage by going upward when expanding outward is not an option. However, adding an extension can have a whole house impact, which is why it’s important to go over all the fine details with a professional design and build company.

Stairs, mechanical elements such as water heaters, furnace and air conditioning are aspects of a second story extension that can impact your home. For families that already love their neighborhood and don’t want to go through the process of relocating to a larger home, adding an extension is the perfect solution.

Our team of design-build experts is ready to add some extra space to your home. We will determine if your home is a good candidate for the upward extension and work with your design idea to realise your vision.

In-law additions

The multigenerational household is often pushed for space. An extra bedroom, closet, bathroom and storage area that a standard in-law suite provides can knock down a lot of the stress that multigenerational households experience when space is limited.
