Frequently Asked Questions

How do I choose between different room and home additions?

This all depends on your needs, the general layout of your home and whether you have found a professional that can handle your project in every aspect. Does your plan include just an expansion of existing rooms or a change of the complete layout?

Whether you’re considering selecting some of the versatile and customizable room additions or just need some expert advice on how to improve the existing space, you can count on our experts. Besides, here at Lars Architecture you can count on us if you plan to:

How will a room addition tie into the house?

This all depends on how well your room addition was designed and carried out. Usually, when you find a team of experienced contractors to handle the project, they will make sure to make a natural-looking transition between the new room and the rest of your house. They’ll accomplish this by imitating the style of the rest of your house. For instance, they’ll install the same fixtures, finishes, hardwood, tiles and padding.

Can I add a bathroom in a master bedroom?

Of course, building an ensuite bathroom is a great option that’ll grant you more privacy and comfort. Whether this would be possible depends on your floor plan, existing utilities, plumbing and electrical functions.  Indeed, this is a great idea, but consult with your local provider to see if it’ll fit your budget. You can call Lars Architecture today to get the best advice from our specialists.

What should I ask a home addition company?

First off, you should always check if you’re dealing with a licences company that hires insured and bonded professionals. Secondly, you should check if the company offers a full scope of services needed to bring your concept to life, or you would need to hire other professionals to perform some individual tasks, like post-construction cleaning, electrical work and installation of certain home appliances. Lastly, you should ask whether a company offers some sort of guarantee.

If you contact Lards Room Additions, you wouldn’t have to worry about this and you’ll get straightforward answers from us.
