Commercial property development finance in Marylebone funds the land purchase and construction of commercial schemes, from a single conversion to a multi-phase regeneration. We arrange it across Greater London for developers, investor-developers and operators, structuring the debt and equity a scheme needs and placing it with the lenders that actually back that asset class.
We underwrite a Marylebone scheme on its commercial fundamentals, with the local residential market as a gauge of exit liquidity for any residential element. That market is steady, around 1,531 residential sales in the past year at a £800,000 median, which helps test the values for the homes in a mixed-use or conversion scheme.
Development finance structures for Marylebone schemes
We arrange the whole capital structure for Marylebone commercial schemes. Senior development finance funds the bulk of the build, typically to 65 to 70 percent of cost and 60 to 65 percent of gross development value. Stretch senior and mezzanine finance lift leverage when the appraisal supports it, reducing the equity you commit. JV equity fills the remaining gap for developers scaling beyond their own balance sheet. For operational schemes that let up or trade after completion, such as student accommodation, care homes, hotels or self-storage, stabilisation finance carries the asset from practical completion through to stabilised income. Once the scheme is stabilised or sold, development exit finance refinances it onto cheaper money while units sell or let, releasing equity for the next site in Greater London.
Commercial development we finance across Marylebone
Each commercial asset class is underwritten on different tests by different lenders, and we arrange finance for all of them in Marylebone and across Greater London. That covers student accommodation and offices, warehouses and logistics, care homes and healthcare, retail, hotels and leisure, industrial and mixed-use schemes, and the higher-growth classes of self-storage, data centres and life sciences. Knowing which lender backs which sector here, and at what leverage, is the work we do before a scheme ever reaches a credit committee.
Finance we arrange for Marylebone schemes
What the Marylebone market means for your appraisal
Marylebone sits at the premium end of the Greater London market, where higher values support higher-specification commercial schemes. Strong end values can carry higher finance costs and justify stretch senior or mezzanine leverage, though lenders will want a disciplined cost plan and a credible exit at the values assumed.
Residential market depth as exit context
Residential sold-price depth is one input a development lender uses to gauge exit liquidity, particularly for the residential element of mixed-use, build-to-rent and conversion schemes. Marylebone recorded around 1,531 residential sales over the past year at a median of £800,000, which makes the local market steady. New-build stock carries a premium of 100% over existing stock here. Commercial values turn on covenant, yield and sector demand, which we assess scheme by scheme.
This residential mix is exit context for the homes within a mixed-use or conversion scheme. It is not a guide to commercial values, which are sector and covenant driven.

FAQ
Commercial property development finance in Marylebone: common questions
How much commercial property development finance can I raise in Marylebone?
Most senior lenders fund up to 65 to 70 percent of total cost, capped at 60 to 65 percent of gross development value, with stretch senior or mezzanine lifting that toward 85 to 90 percent of cost on a strong scheme. The Marylebone exit market, currently steady, informs the gross development value a lender will accept.
Which lenders provide development finance in Marylebone?
We hold more than one hundred lender relationships across banks, challenger banks, debt funds and private capital. The right lender for a Marylebone scheme depends on the sector, the leverage you need and your track record, and we shortlist the desks most likely to back it across Greater London.
How does the Marylebone residential market affect a commercial scheme?
It matters mainly as exit context for the residential element of mixed-use, build-to-rent and conversion schemes. HM Land Registry records a £800,000 residential median in Marylebone over the past year across roughly 1,531 sales, with flats around £700,000. Commercial values, by contrast, turn on covenant, yield and sector demand, which we assess scheme by scheme.
Do you fund commercial development beyond Marylebone?
Yes. We arrange commercial property development finance across the whole of Greater London and the wider UK, with the same approach: model the capital stack, match the scheme to the lenders that back its sector, and negotiate terms on the developer's behalf.
