The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"Hi, Jeremy & Ian exceeded my expectations. They walked me through the process with a preview, Stellar performance on my closet finish that had collapsed. I was smiling at each phase of job & once the job was completed btw I had a permanent smile 😃.. I was soooo.. very happy with the high quality & very professional work performance that I must share with anyone looking to have a closet repair project done. I will be referring Jeremy & Ian both to friends & family ! If. I need any future home-related projects requiring a professional they will be my primary choice. Best, Arlana Hines"

"Daniel has done two projects for us where he assembled a large dining room table and large china cabinet both over ten feet long. His work was impeccable and he was professional and courteous. We got both pieces from Wayfair and the required intense installation with 100â  s of pieces. He has all the tools and went above and beyond to get it done. I would recommend Daniel for any type of handyman job"

Treehouse Builders questions, answered by experts

Sustainable materials and energy-efficient designs support greener construction options.

When designing an attached greenhouse, several factors should be considered. These include the orientation and positioning of the greenhouse to maximize sunlight exposure, the structural integrity of the connection to the house, sufficient insulation to regulate temperature, proper ventilation for airflow, and adequate space for plants and pathways. If you’re restricted because of your budget, go with a simpler design to maximize the use of your money.

Before you get started on your hydroponic garden project, decide on your garden’s location. For a small office or home garden, consider an indoor hydroponic garden. Contrarily, if you plan on making a profit from your hydroponic garden, you might need to rent land or indoor space to grow your plants.

Don’t forget to factor in the climate where you live during the planning stage. If your area is prone to bitter cold and heavy snow, you might want to invest in stronger greenhouse materials like a concrete slab, steel frame, and glass walls or plan to take your greenhouse down for the winter.

Increases living space and adds value to the home through enhanced utility.
