Frequently Asked Questions

What is the best addition to a house?

It’s hard to name a single home addition in Portsmouth as the “best” one because it all truly depends on your needs, priorities, budget, and more. For example, a second story addition can be great for a growing family without strict budget constraints, while a simple garage conversion can be far more practical for those looking not to spend too much time or money on the project. Some popular and worthwhile options include offices, primary suites, and accessory units.

How do you tell if your foundation can support a second story addition?

Determining the strength of your foundation is not something you can do yourself unless you have extensive experience and education in the field of structural engineering. To make sure it’s safe to build a second floor on your house, it’s recommended that you hire an engineer to perform a structural evaluation and determine whether your foundation can support the second-story addition or if reinforcements will be necessary.

How long does it take to build a 2nd floor?

For second story additions in Portsmouth, the timeline varies based on things like your house’s structural integrity, the scope of the work, and any required permits. In some cases, it could be a few months, but more complex projects could take even longer. Let’s not forget that external factors like the weather and material availability can impact the timeframes too. Generally, leaving the project to the trusted professionals is the best way to make sure it’s handled properly, safely, and as efficiently as possible!

What is a good size for a master bedroom addition?

Generally, the most desirable dimensions for a master bedroom addition are around 200-250 square feet. A bedroom of this size offers sufficient space for a king-size bed, a basic bathroom and closet, and some additional furniture of your choice. Some people, however, opt for a master suite, usually between 400 and 500 square feet.

Does adding a master bedroom increase home value?

Market conditions are not always the same, but on average, master bedroom additions in Portsmouth generally add more value to the property than an expansion of the living area, for example. If you’re considering expanding your property for its resale value, an experienced local real estate agent would be able to provide the most accurate information.

What to do before home addition?

Before starting your property improvement, it’s recommended that you explore various options and assess whether the budget you had in mind can cover it completely. You should discuss this with a reliable professional who can estimate the expected costs and work with you on the project design to incorporate your ideas. Professional home addition contractors will give you the most accurate information about technical details, functionality, building materials, and permit requirements.

What is the benefit of ADU?

An accessory dwelling unit is a flexible way to create a separate residence nearby. It comes in various options, from detached units to attached suits, and is usually more budget-friendly and convenient compared to purchasing another house. By having ADU builders in Portsmouth create a smaller, fully functional living area, you can stay close to family members like elderly parents or adult children, accommodate guests or caretakers, and even generate rental income if you decide to lease it out!

How big can an ADU be in Rhode Island?

Rather than a fixed limit, the size of an accessory unit in Rhode Island is generally determined by the lot size and the floor area of your primary residence. Typically, the floor area can’t exceed 35% of your main residence’s, though this excludes areas like basements, decks, and porches. But you do have to make sure that the unit meets the minimum size requirement of 400 square feet. Since laws and regulations surrounding this can get quite complex, it’s always best to consult with ADU builders near you to navigate the process more effectively!
