We invite you to use our PHNX Cost Estimator tool to give you a general idea of the size, scope and cost of what you want. It’s easy to use and play with; you can try out as many different variations as you want. You can also enter your email address to send yourself a copy of the result.
If you would like help selecting a property, PHNX Architectural Services is available to help you determine the feasibility of any property you’re considering for your project. This is highly recommended, as there can be costly hidden issues that could render your project unfeasible, especially on undeveloped properties.
If you have lost your home in a wildfire, feasibility issues are a little different. PHNX can help you work with your insurance company to determine a path forward that will minimize additional investment on your part. Every policy is different; we’ll help you create the right design for your budget.
With PHNX, we provide you with the PHNX 10% Concept Budget before you have to spend tens of thousands of dollars. For a $6,000 non-refundable fee (for most homes under 3,000 SF), PHNX will work with you to create a unique, custom design. Deliverables include a full Schematic Design Package (plans, elevations, sections, 3-D modeling), Tentative Design & Construction Schedules and a budget estimate within 10% of eventual cost. This 10% Concept Budget includes hard costs (actual construction) and soft costs (fees - design, permitting, and outside consultants). Depending on site complexity, it may or may not include site work. If there are complex site issues, their potential cost will be addressed - but we may need to do additional work before we get a more accurate cost estimate.
There are no overages in the PHNX Process. California law requires all construction contracts to include a contingency to cover unforeseen circumstances. We include a 5% contingency in our 10% Concept Budget. PHNX minimizes reliance on the volatile labor and materials market and controls the entire delivery process to such a degree that we are confident any bumps will be absorbed by the contingency. Anything remaining in the contingency after completion will be refunded to you.
It takes about two months to produce a set of construction documents, and about three months to process through a jurisdiction’s plan review/approval system (although this varies greatly, depending on jurisdiction. PHNX has very little control over this phase of the process, but we do our best to plan for a reasonable length of time and stick to it).
Construction of a PHNX Home takes about six months - less than half the time of a traditional build - wood, steel or even ICF. PHNX Development has painstakingly analyzed every aspect of the design/build process, looking for any opportunity to reduce steps and streamline design and construction. A good percentage of a PHNX Home is built with Component Based Design materials and methods; this is what enables PHNX to have a higher degree of confidence and certainty in the project delivery process.
The next step is to start looking out for things you like (and don’t like!) online and in real life. Snap, clip, post, save… Keep everything organized, and be sure to make notes on why you liked or didn’t like a particular image. Share these with your PHNX Designer ahead of your kick-off design meeting.
Spend time paying attention to how you live. If you are a wildfire survivor, walk yourself through a typical day in your previous home. What’s the thing you loved the most about your previous home? What would you have loved most to change? What one thing would disappoint you the most if your new home didn’t have it? The PHNX Design Questionnaire is a great tool to get you on the right track.
We will need a survey of your property to be completed in order to start design. Whether you go with PHNX or someone else, if you are going to build a new home you will need a survey so it’s not a bad idea to have one done right away. They usually take about three to four weeks to be completed by a licensed land surveyor. If you aren’t sure how to find a land surveyor, your PHNX Designer can help you find one. If your property isn’t very complex, we might be able to begin concept design while waiting for the survey to be completed.
Collect any documents you have about your property, your neighborhood, your HOA… it’s important that your PHNX Designer has everything they need right from the beginning in order to avoid costly delays.
Most importantly, what we want to know from you is the “What” and the “Why”. Let us figure out the “How” - it’s what we do. If you find yourself saying things like “I want the stairs to the right” or “the master suite needs to be between the bedroom and the kitchen”, you're getting into the "how". Your PHNX Designer needs to know WHY you want the stairs to the right, or WHY your master needs to be between those two rooms.
When we design buildings, there are many more things to take into consideration than how the plan lays out. Budget, code, structural feasibility, massing, roof shapes, etc etc etc…. Your PHNX Designer needs to have the flexibility necessary to find the right solution that satisfies your needs, as well as all of those other concerns; being armed with a solid understanding of your priorities enables us to not only give you what you want, but also ensure that we can actually build it!
Typically banks want a large down payment, usually in the range of 20%-30%, or even more. There are even circumstances when they want to see assets equivalent to the amount of the loan. In certain cases, some banks will accept the land as collateral.
When a project is being financed with a construction loan, the lender becomes part of the design/build team. They want to see the plans, budget and schedule, and they have to review and approve the contractor. A loan will cover the cost of design services and permitting, but the money won’t be accessible until the funding is in place at the start of construction - so you will have to fund those services yourself and get reimbursed once the loan is funded.
You will not receive a lump sum. Instead, the loan is disbursed through a service called Fund Control. The owner and contractor jointly file for a “draw”; documentation is required, and the appropriate funds are paid out, usually in a few days, over the course of construction. Sometimes the lender will send an inspector to the site to evaluate progress to ensure that what is being funded is being completed.
Upon receiving the occupancy permit, your loan is then rolled over into a mortgage and paid back over time. If at completion there are unused loan funds, those will not be paid out but instead used to reduce the principal of the mortgage.
The manufacture of proprietary, engineered structural building components is an emerging industry. We are now seeing second and third generation companies producing remarkable products that, in tandem with advances in Building Information Management (BIM) technology, are able to deliver custom designed structural systems in unprecedented time.
PHNX works with several of these Component Based Design manufacturers to design and build the PHNX Home (see our PHNX Specification Manual for more information). We send them our detailed schematic plans during the initial concept design phase, and they are able to design a system and cost it out - sometimes to the penny - in less than a week. Since these elements are manufactured and not site built, the costs are more stable and predictable. There are regular price increases, but these are scheduled and the PHNX team will try to schedule a purchase prior to an increase if possible. If not, we know it will happen and can write it into the budget.
Component Based Design systems are also much quicker to install in the field. Not only does this enable us to reduce construction site waste and slash construction time, but it also reduces our dependence on site labor - another volatile industry market factor that makes budgeting so unpredictable.
The other PHNX principle is Coordinated Design/Build. Not everything in a building can be made in a factory; on site labor is unavoidable, and all trades are still necessary. The two arms of PHNX Development, Architectural Services and Constructions Services, work equally hand in hand to design the home with materials and methods that make sense for the contractor. From product specification, to location and layout, to even the length of walls and overhangs, PHNX Designers have a set of “rules” to design by. Mostly imperceptible in the overall design of the home, these guidelines enable us to streamline the design and production process, further reducing time and cost.
Because Coordinated Design/Build happens in conjunction with our pre-selected team of reliable PHNX sub-contractors, cost estimates are more predictable and accurate. Our subs know exactly what to expect on any PHNX Home. They spend less time preparing quotes and visiting the site. Your PHNX Designer is equipped with predetermined cost data, enabling them to see the cost of your new home almost in real time.
After approving the concept design and PHNX 10% Concept Budget, there will be about 2-3 months of additional design time and about 3 months of plan review for permitting. We will do another budget check-in before submitting the plans for permit approval, and once we feel confident that plan review won’t require any changes that substantially affect the budget, PHNX will finalize the budget and Penna Construction will provide you with a construction contract fixing that amount.
Please see the PHNX Tech Bulletin post “Five Things to Know if You Want to DIY Your New Home” for more information and this subject.
However, we will be happy to walk through those plans with you find out what things you like or don’t like about the design, and use that input to help us design your new PHNX Home. Having already gone through the design process once, know that the experience will absolutely benefit both you and the PHNX design team. The effort will not have gone to waste.
