Frequently Asked Questions

When should you build an addition?

The clearest sign that you need a home addition is lack of space. Whether you’ve run out of storage space, don’t have enough room to seat your guests in the living room, or have another space limitation issue, it may be time to call our team. The only alternative would be to move house, but the benefits of a home improvement project in Mission Hills generally outweigh the perks of moving.

How can I design an addition to my house?

The best route you can take when it comes to creating a beautiful and practical design for your room addition is to hire a professional contractor in Mission Hills. With a full-service company, you’ll get complete project management from start to finish. Once the initial consultation is conducted and a Design Agreement is signed, our designers will move forward into the design phase, developing options for your addition project. They’ll take note of all of your requests and shape them into cutting-edge plans for our construction team to follow.

How do you manage a home addition?

Home additions take time and the careful coordination of design and build teams. To make sure that the process runs smoothly and there are no surprises or delays, it’s best to put a full-service company in charge of your project in Mission Hills. Lars will provide expert project management to keep your project going according to plan.

How to find a contractor for a home addition?

You can easily arrange a free consultation with our team and go over the most important aspects of your future project. We’ll be happy to hear you out and turn your ideas into beautiful architectural plans.

What is a junior ADU?

A junior ADU (JADU) is an accessory dwelling unit no larger than 500 square feet. It must be situated within an existing or proposed accessory structure or single-family house in Mission Hills, like a garage. Unlike full ADUs, a JADU can use a shared bathroom and only has to meet the “efficiency kitchen” requirement.
