Not all projects require planning permission, as some smaller works fall under permitted development rights. However, this depends on factors such as the type of property, its location, and the scale of the work. As your architects, we can help determine whether planning permission is necessary and guide you through the process, ensuring all requirements are met to avoid delays or complications.
Planning permission focuses on the scale, aesthetics, and impact of your project
on the surrounding area, along with the use of the building, while building regulations
approval ensures that your design meets safety, structural, and environmental
standards.
We’ll handle both aspects for you, submitting applications and liaising with
authorities to secure the necessary approvals for your project. We usually prepare the building regulations package after a successful planning application.
As of 2025, construction costs are typically calculated at around £2500-£2800 per sq.m ex VAT. It’s important to factor in additional costs such as knocking through existing walls, any necessary internal remodelling work, including steel supports, and potential upgrades to bathrooms, kitchens, or other elements.
It also depends on your build route – if it’s a DIY, a self managed or using a main contractor.
For a more accurate and detailed cost breakdown throughout the project, you may wish to appoint a Quantity Surveyor (QS) or an estimator as part of your design team. Alternatively, Build It Cost Estimation offers great impartial cost breakdowns to help you plan your budget.
A planning consultant is a specialist in navigating planning policies. They provide expert advice on obtaining planning permission, understanding local requirements, and resolving any potential challenges. While they are often associated with complex or sensitive projects, planning consultants can be invaluable for smaller projects too, such as new dwellings, conversions, or navigating prior approval processes. At JNC Architecture, we frequently collaborate with planning consultants on various projects to ensure your project is well-prepared, increasing the likelihood of approval and streamlining the process for a smooth outcome.
Loft conversions can vary in cost depending on the complexity of the project and whether you wish to include dormers. As of 2025, according to checkatrade, the average cost of a 30m² loft conversion in the UK can range from £40,000 to £75,000+ depending on the type you choose and several other variables.
It’s important to consider the cost of upgrading the existing floor joists to support the additional load, the cost of relocating or adding a new staircase, and any drainage extensions needed. Additionally, you may need to include costs for upgrading insulation, structural works, or any new bathroom installations if required. For a detailed cost estimate throughout the design and build process, consider appointing a Quantity Surveyor (QS) or estimator to ensure a more thorough breakdown. Alternatively, Build It Cost Estimation offers great impartial cost breakdowns to help you plan your budget.
