Understanding ground up residential
Comparisons between ground up residential and its neighbouring development finance options turn on cost of capital, speed, and how the facility is repaid. Ground up residential applies where funding is drawn in stages against build progress rather than advanced in full at the outset.
Structurally, the facility is secured on a first charge over the site, supported by a debenture and personal or corporate guarantees, written over terms of nine to twenty-four months, aligned to the build programme plus a sales period, with typically up to 65% of gross development value, or 80% to 90% of total development cost, whichever bites first. Lenders assess the exit before the entry: the facility is repaid from unit sales or by refinancing the completed scheme onto investment or term debt. That ordering explains why two applicants with identical income can receive materially different terms — the credit question is whether the repayment route survives a slower market, not whether the borrower looks creditworthy today.
Activity in this segment comes from peer-to-peer and syndicated platforms, specialist development lenders, debt funds and institutional capital and challenger banks with construction desks. Each prices the same development finance case against its own funding cost and risk appetite, which is why the same ground up residential case can attract offers several percentage points apart. The Financial Conduct Authority supervision shapes conduct standards and, where the borrowing is regulated, the advice and disclosure obligations that sit around the transaction.
Eligibility criteria for ground up residential
Eligibility for ground up residential is assessed on the asset first and the applicant second. Lenders test the appraisal — build cost, contingency, professional fees and end value — stress-tested against slower sales and cost inflation, then satisfy themselves that the facility is repaid from unit sales or by refinancing the completed scheme onto investment or term debt remains achievable under stressed assumptions. Trading history, sector, and the quality of the security all move the answer, and a marginal case is far more often declined on evidence gaps than on the underlying numbers.
A complete submission normally contains a detailed cost appraisal with contingency, the build programme and contractor details, a schedule of the developer's completed projects and an independent monitoring surveyor's initial report. Where any of these are missing, underwriters price the uncertainty rather than ignore it, so incomplete packs tend to return higher rates or lower advances rather than an outright refusal. Preparing the pack before approaching lenders is the single most effective way to protect the terms available.
Adverse credit, short trading history, or an unusual asset does not automatically exclude an applicant. It moves the case towards specialist development lenders and debt funds and institutional capital, where criteria are set case by case. The trade-off is cost: flexibility on criteria is almost always paid for in margin, fees, or a lower advance against value.
Cost structure of ground up residential
Pricing is built rather than quoted. The headline rate reflects a margin plus arrangement and exit fees, with interest charged only on funds drawn rather than on the full facility, and the effective cost only becomes visible once arrangement fees, valuation and legal costs, and any exit or early-repayment charge are added to the same calculation. Comparing two offers on rate alone routinely selects the more expensive facility.
Three variables move the price materially: the advance requested against value, the strength of the facility is repaid from unit sales or by refinancing the completed scheme onto investment or term debt, and the time the lender is exposed. Reducing the advance is usually the most efficient lever, because it lowers loss-given-default for the lender and therefore the margin charged. Figures discussed at enquiry stage are indicative and subject to valuation and full underwriting.
Borrowers should also price the cost of delay. Terms are typically issued within a week of a complete appraisal, with drawdown following legal and monitoring-surveyor sign-off in four to eight weeks. Where a transaction has a fixed deadline, a slightly higher margin from a lender that can meet the date is frequently cheaper than a lower margin that misses it and forfeits a deposit or a negotiated purchase price.
How a ground up residential case is assembled
Consider a borrower using ground up residential where an existing building is converted to a new use under permitted development. The starting point is the security: an independent valuation establishes what the asset supports, and typically up to 65% of gross development value, or 80% to 90% of total development cost, whichever bites first sets the realistic ceiling on the facility. The gap between the ceiling and the funds required is the equity or additional security the borrower must contribute.
The facility is then sized against the appraisal — build cost, contingency, professional fees and end value — stress-tested against slower sales and cost inflation, and the term is set by the repayment route rather than by preference — the facility is repaid from unit sales or by refinancing the completed scheme onto investment or term debt. Costs are modelled across the full term, including arrangement and exit fees, so the comparison against alternatives is made on total cost rather than on headline rate.
This example is illustrative. It is not a quotation, a recommendation, or evidence of available terms; actual pricing depends on valuation, credit assessment, and the lender's appetite on the day. Its purpose is to show the order in which decisions are made, because borrowers who understand that sequence present far stronger applications.
Common use cases for ground up residential
Ground up residential is most commonly used where a partially built scheme requires a developer exit facility, a heavy refurbishment involves structural change or extension and an experienced developer funds several plots within one programme. What these situations share is a mismatch between the timing of a cost and the timing of the funds that will meet it; the facility exists to bridge that mismatch at a known price rather than to fund an indefinite shortfall.
A second group of cases is structural rather than urgent: a site with planning consent is built out for open-market sale and an existing building is converted to a new use under permitted development. Here the borrower is choosing how to hold an asset over time, and the analysis is closer to a capital-structure decision than a funding emergency. Term, covenant flexibility, and early-repayment terms matter more than speed.
The route is a poor fit where the repayment plan depends on an event outside the borrower's control, or where the underlying business needs additional working capital rather than secured borrowing. In those cases the honest answer is that ground up residential would refinance a problem instead of resolving it.
When another route is better
The nearest alternatives are a commercial mortgage once the scheme is complete and income-producing, a bridging facility where works are cosmetic rather than structural and a developer exit facility to reduce cost once the scheme is watertight. Each solves a slightly different problem: some are cheaper but slower, others are faster but priced for short exposure, and a few avoid taking a charge over the asset altogether. The right comparison is total cost over the period the money is actually needed.
Where the requirement is short and the exit is certain, a short-dated facility usually wins on total cost even at a higher rate, because the interest is charged for months rather than years. Where the asset is held for the long term and the income is stable, the opposite is true and a term facility priced on a margin plus arrangement and exit fees, with interest charged only on funds drawn rather than on the full facility is the cheaper way to hold the position.
A broker or adviser adds most value at this point rather than at application. Comparing specialist development lenders, debt funds and institutional capital and challenger banks with construction desks on a like-for-like basis, including fees and exit terms, is the step that determines the cost of the transaction — the paperwork that follows is largely administrative.

Who is ground up residential suitable for?
Ground up residential suits borrowers whose requirement is secured on a first charge over the site, supported by a debenture and personal or corporate guarantees and who can evidence a credible repayment route. Lenders test the appraisal — build cost, contingency, professional fees and end value — stress-tested against slower sales and cost inflation before considering the applicant's wider profile, so suitability is determined by the asset and the exit as much as by trading performance.
How much can be borrowed against ground up residential?
Advances are governed by an independent valuation, with typically up to 65% of gross development value, or 80% to 90% of total development cost, whichever bites first. The realistic ceiling is whichever is lower: the advance the security supports, or the amount that satisfies the appraisal — build cost, contingency, professional fees and end value — stress-tested against slower sales and cost inflation. Requesting less than the maximum usually improves both the rate and the likelihood of approval.
How is ground up residential priced?
Pricing is constructed from a margin plus arrangement and exit fees, with interest charged only on funds drawn rather than on the full facility, then adjusted for the advance requested, the strength of the exit, and the lender's exposure period. Arrangement, valuation, legal and any exit fees should be added before comparing offers, because the lowest headline rate is frequently not the lowest total cost.
What documentation is required?
A complete submission normally includes the build programme and contractor details, a schedule of the developer's completed projects, an independent monitoring surveyor's initial report, planning consent and approved drawings and a detailed cost appraisal with contingency. Gaps are priced rather than overlooked, so assembling the pack before approaching lenders protects the terms available and materially shortens the timetable.
How quickly can ground up residential complete?
Terms are typically issued within a week of a complete appraisal, with drawdown following legal and monitoring-surveyor sign-off in four to eight weeks. Valuation and legal due diligence account for most of the elapsed time, so instructing solicitors early and clearing conditions in parallel rather than in sequence is the most reliable way to hold a completion date.
What are the main risks of ground up residential?
The principal risks are contractor failure part-way through the programme, cost overrun exhausting the contingency line and programme delay extending the term and the interest cost. Because the facility is repaid from unit sales or by refinancing the completed scheme onto investment or term debt, a repayment route that slips is the most common cause of difficulty; building contingency into the timetable is considerably cheaper than negotiating an extension under pressure.
