On the other hand, if you plan to stay in the house on a long-term basis, you can even opt for a ‘One issue at a time’ approach and replace all the things necessary over why not try this a longer period of time. This will ensure that your budget is spent more evenly and you do not have to worry about escalating costs. One downside of this approach is that you may lose the consistency of the kitchen design if you do it over a longer period of time. Design service can be broken down into creative design and technical design. For creative design service, which is almost always optional, you’ll work with an architect or interior designer to reimagine the space. This added layer of service will generally cost between 10-20% of your construction budget, depending on the level of service included in your design package (though, not all firms determine their fees based on cost of construction — some may charge a flat fee based on project scope and anticipated duration, for example). So, for a $50,000 kitchen renovation, you might expect to pay your architect or designer $5,000 to $10,000.
