"I searched many and started off with others and nobody came close in handling what we needed. I found Richard, he came in and took care of it all; it was completed in a timely manner with his accurate thinking. He definitely thought ahead and it saved me a lot of time, grief and money. He got ahead of any issues and resolved potential problems that could arise. He knew exactly what the city would require and did what needed to be done which saved us an untold amount of time and money. I did not know him from Adam, he works at a very different level of ability and knowledge. His pricing for me was the best! He is a gem, get him if you can!"

We are a reputable architectural design company that specializes in a variety of interior design and spatial planning projects. We take pride in our ability to exceed expectations in all aspects of business. We look forward to building long-term relationships with our clients.

"Do not recommend. I hired Hedgemond Planning and Development to prepare ADU plans and submit them to the city for approval. Nearly two years later?and after paying over $10,000?I still do not have an approved ADU. Throughout the process, timelines were repeatedly missed and expectations were not met. The company overpromised and underdelivered. I chose them because their pricing was lower than other firms, but the delays, lack of results, and ongoing frustration ended up costing far more in the long run."

Architects questions, answered by experts

Blueprints for standard home construction will usually range from $1,500 to $2,500 and average around $1,800. Your pricing will likely be higher if you’re building a custom home, as you’ll need to pay a structural engineer to weigh in on building safety. The size of your project, the number of rooms, and the type of drawings you need can also play a role in your total cost.

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

You'll find Arts and Crafts homes across the country in varying styles. On the East Coast, bungalows and Tudor Revivals fill the Boston area through New Jersey. In the West, Mission-style homes incorporate terracotta shingles, white stucco siding, and rounded archways.

Designs typically take 2-6 months, depending on factoring, project size, and customization needs. Larger or more complex designs may require additional time for approval and revisions.
