Essential Guide to Setting Up Your Design and Building Budget

Axe Construction • August 20, 2024

Your house is an integral part of your life. If you are embarking on renovation or construction projects, proper design and building budget knowledge is essential. Why? Because budgeting helps ensure your project stays on track financially, avoids unnecessary delays, and meets your expectations.

Whether you are doing the project yourself or hiring a professional architectural design company (a much more efficient option, by the way!), setting up a budget is something you can’t ignore. In fact, according to a survey by KPMG in the U.K., 69% of major construction projects suffer from cost overruns, highlighting the critical need for accurate budgeting and effective cost management.

So, all the more reason to start budgeting your design and construction before anything else. Now the question remains – how do you do this?

Well, with our years of experience, we have put together a basic guide that will walk you through the essentials of setting up your design and building budget, from initial planning to final cost estimation and expense tracking.

Design planning

Design is the cornerstone of any successful renovation, extension, or conversion project. It’s the phase where ideas take shape and translate into actionable plans.

Designing also helps with the scope of the project. You can understand the project’s requirements and expectations, reducing the risk of unforeseen expenses. Some of the major benefits of design planning include:

  • Enhances cost efficiency
  • Facilitates better communication among your team (architecture designers, etc)
  • Define a healthy scope of the project and expectations

Steps to follow in design planning

  • Initial consultation: If you are hiring a building company, meet with the designers, renovators, and builders to discuss ideas, preferences, and requirements.
  • Concept development: Make preliminary sketches and concepts to visualise the project’s potential.
  • Detailed design and cost: Once the experts draw a detailed design, they will give you a final budget.
  • Final approval: Look carefully for any changes you may prefer before finalising and moving to the budgeting phase.

Design expenses

Design costs are a substantial portion of the overall project budget. These charges often include the costs of architectural and engineering services, interior design, and other related operations.

Some of the most common design expenses for any residential building project include the following:

  • Architectural design fees could be a percentage of the total construction cost or a fixed fee.
  • Costs of structural, mechanical, electrical, and plumbing engineering services.
  • Permits and approvals from local authorities also require a certain fee.
  • Additional expenses of electing finishes, fixtures, paints, etc.

Ways to manage design expenses

  • Budget: Set aside a certain portion of your total budget for design-related tasks.
  • Negotiate: Negotiation and some compromise with the designers could help you achieve your vision within your design investment.
  • Monitor the changes: Keep track of any changes in the design phase that might impact costs and adjust the budget accordingly.

Cost estimation

We often indulge ourselves so much in designs and colour themes that we forget that cost is the backbone of any project. Begin by detailing all probable expenses, including the cost of land, building, and materials, as well as fees for architects, planners, and legal counsel.

Budget allocation involves predicting the total expenses required to complete the project based on current market rates and historical data.

Some of the key metrics to follow are:

  • Cost per square foot based on the total area of the project.
  • Building costs, depending on specific items or activities, such as labour charges per hour.
  • Compare your project cost estimation to similar ones.

Popular methods to use for cost estimation

  • Historical data: This requires you to compare historical data from similar projects to estimate costs.
  • Three-point estimation: This is very useful in the case of large projects. This includes the best-case, worst-case, and most likely scenarios to provide a range of potential costs.
  • Bottom-up estimation: This estimates the cost of each task and combines them to get the total project cost.

Monitoring and tracking expenses

Cost estimation is only the first step in the budget control process. Throughout the procedure, you must track your expenses to stay within budget and manage resources effectively.

Maintaining a complete record of all expenses, including supplies, labour, permits, and unforeseen charges, will allow you to acquire a thorough knowledge of where your budget is going.

Moreover, consistent expense tracking helps maintain transparency with your designers, engineers, permits, and other expenses. Some of the major benefits of expense tracking are:

  • Maintain control over project finances and prevent overspending.
  • Provides complete transparency among people involved with your project.
  • Provides current financial information, allowing for more informed decision-making.

Tools for tracking design and building budget

  • Project management software: Popular software like CoConstruct or Procore can track expenses in real time.
  • Spreadsheets: If using software is too much of an inconvenience, you can opt for detailed spreadsheets to log expenses manually.
  • Regular audits: This is really important. Conduct frequent financial audits to identify and resolve anomalies.

Choosing the right company for your design planning, expenses, and project budget

While keeping a proper design and project budget is your responsibility, choosing a reliable company with expert suppliers, contractors, architectural designs, and builders will help you achieve quality work within your budget.

A positive relationship with the team you is collaborating with can have a significant impact on the seamless execution and success of your project. Choose a company like AXE Construction , who are able to take on substantial house extensions, kitchen renovations, and other home renovation projects.
