    Frequently Asked Questions

    Is it worth it to add on to your house?

    If you’re thinking about selling your property and want to increase its market value, or you simply wish to add a bit of luxury and convenience to your life, then you should definitely think about a house addition. However, to achieve your goals successfully, you will need the help of a reputable certified home addition contractor.

Our seasoned team of custom home builders will come up with a carefully designed strategy that will boost the functionality and aesthetic appeal of your home, making it hard for any prospective buyers to say no to it. 

    Is a home addition a good investment?

    Kitchen, bathroom, room, second story, suite, and house additions can all play a crucial role in adding to the resale value of your property. If you plan to target serious buyers who are ready to invest more in a home that already comes equipped with a luxury sunroom or an in-law suite, then adding on to your house is undoubtedly the way to go. Schedule a consultation with us, and let’s come up with a design plan that will achieve your goals and add value to your home.

    How do I plan an addition to my house?

    House addition projects require a great deal of planning and expertise to be completed up to code. That’s why you should always rely on the professionals for help. Not only will they come up with a bulletproof plan for your home renovation project in San Diego or the area, but they’ll also prevent you from inadvertently making bad decisions that can end up costing you a fortune.

    Whether you’re reconfiguring your existing floor plan or designing an entirely new one, we have a talented team of home architects and designers to ensure that every stage of the project, from the initial planning to the final execution, goes smoothly.

    How do I design an addition to my house?

    When designing an addition to your San Diego home, be that an entire second story or a new bathroom, you want to ensure that it suits your needs and living style. That’s exactly what Lars Architecture and Construction can do for you! We always take the time to consult with our clients and then, based on their input, create options designed to exceed their expectations and add lasting value to their home.

    Is it worth it to build an ADU?

    Adding an accessory dwelling unit to your property in San Diego is undoubtedly worth it, and these are some of the top reasons why you shouldn’t wait any longer before you call your trusted local ADU contractor and schedule a consultation:

    • Increased property value: Building an ADU is one of the most efficient ways to boost the resale value of your home. So, if you’re looking for a house addition project that will provide you with a high ROI, building an accessory dwelling unit is the way to go.
    • Rental income: If you’re looking for an easy way to generate some additional income, you can always turn your ADU into a vacation rental. This option is much better than renting out a spare room on Airbnb because both you and your guests will have complete privacy.
    • Housing for adult children: If your child is almost an adult and on their way to becoming fully independent, then an ADU can be a great temporary housing solution for them. They will still be close to you but have the privacy they need.
    • Functional office space: If you work from home, why not turn your ADU into an office? You’ll have your peace and quiet and a lot of space to meet with your clients.

    As the leading custom home and ADU builders in the San Diego area, Lars Architecture and Construction is your go-to business if you’re considering building an ADU on your property. Feel free to share your needs and ideas, and our team will do everything in their power to build you an accessory dwelling unit that meets and exceeds your expectations and requirements.

    Is it cheaper to buy or build your own custom home?

    Although the cost of your project may vary depending on the type and scope of the work, its complexity, and the materials you choose, building a custom home is always less expensive than buying one. 

    Moreover, if you’re looking to improve your dated house in San Diego with modern features and a new floor plan that’s designed for your own needs, a whole home remodel is the perfect solution.  

    Since we can’t give you an exact answer without knowing the details of your architectural plans, it would be best to schedule a consultation with us. After evaluating your needs, our expert team will provide you with an accurate price estimate for your custom house building plan.

    Where do you start with whole home remodeling?

    A whole home remodel requires dedicated planning and a systematic approach. Thanks to years of industry experience, you can rely on our seasoned team to deliver. There are, however, a few things you should consider before getting in touch with us:

    • Be sure to identify your remodeling needs.
    • Determine the budget for the project you wish to undertake.
    • Choose a design style that works best for you.

    How long does a whole home renovation take?

    A whole house remodel can take a long time, depending on a number of factors, including complexity and the size of your San Diego residence. For instance, renovating a larger home requires more effort than remodeling a smaller one. You should also keep in mind that the materials and products used, the number of people working on the project, and whether there are any design modifications made during construction will also affect the time required for remodeling.
