โ˜…โ˜…โ˜…โ˜…โ˜…

Got planning drawings done for a rear extension in Milton Keynes. Clear concept, accurate measured survey and the planning drawings submitted for us. ยฃ1,825 and the householder application was approved without fuss. Great value versus a full architect for a straightforward job.

Planning plus building-regs drawings for the side return in Milton Keynes. Planning and building-regs drawings done together, structural calcs coordinated with the engineer. ยฃ3,525 all in and the builder priced straight off the package. Saved a lot of back-and-forth on site.

Used an architect end to end on the Milton Keynes project. Full service from first sketch through planning and building regs to site visits. ยฃ7,025 (around 11% of the build). The design got far more out of the space than we'd imagined and they handled every approval.

Architectural Services in Milton Keynes โ€” FAQs

In Milton Keynes planning drawings for an extension typically cost ยฃ1,200-ยฃ2,500, a full plans-and-building-regs package ยฃ2,500-ยฃ5,000, and a full architect service ยฃ4,000-ยฃ12,000+ (often 7-15% of the build cost). For most home extensions an architectural designer can do the drawings for 20-40% less than an ARB-registered architect.
Both can design an extension and submit a planning application in Milton Keynes โ€” only the title 'architect' is legally protected (ARB-registered). For a straightforward extension or loft a qualified architectural designer or technologist (CIAT) is usually enough and costs less; a full ARB-registered architect adds the most value on complex, bespoke or high-value projects.
Many extensions in Milton Keynes fall under permitted development and need no planning application, but anything beyond the size limits, on designated land, or to a listed building will need householder or full planning permission. Your designer will advise which route applies and prepare the drawings either way, and a Lawful Development Certificate is worth getting to prove permitted-development work is lawful.
Planning drawings show the council what the extension will look like and where it sits; building-regulations drawings show your builder how it is constructed to meet structural, safety and energy standards. Most Milton Keynes projects need both, and the statutory planning fee is paid separately to the council, not to the designer.
In Milton Keynes concept and planning drawings usually take two to five weeks after a measured survey, then a householder planning decision adds around eight to twelve weeks, with building-regs drawings following once the design is settled. Allow three to four months from first meeting to approved plans for a typical extension.
