Capital Architecture for Property Investors
Most property investors with SPVs believe the structure is sorted. The SPV is the right first step. But it does not touch inheritance tax, it does not address what happens if the portfolio grows beyond the BPR threshold, and it does not have a strategy for what comes after you. The architecture that does exists. Most investors have never been shown it.
The gap most investors do not see
An SPV ring-fences liability. It separates one property from another. It is a sensible, standard structure and your solicitor was right to recommend it. But an SPV is a container. It is not a strategy. It does not answer the questions that matter most: what happens to this portfolio when you die, what happens if it grows beyond the Business Property Relief threshold, and what happens if your children inherit it and one of them divorces.
The IHT exposure on a property portfolio is often the largest single financial risk a family faces. A £3m portfolio with no estate planning architecture could cost your estate £1.2m in inheritance tax. That is not a worst-case scenario. That is the default.
The architecture that addresses this exists. It uses freezer share instruments to lock the estate at today's value — meaning all future growth sits outside the IHT net permanently from the point the structure is implemented. It uses a family investment company or trust layer to ensure the next generation can receive the benefit without triggering a taxable event. And it is designed with a strategy: what happens if it grows, what happens if you split up, what happens if you pass it down.
The audit maps your current position against this architecture. It shows you what layer you have, what layer you are missing, and what that gap is costing in real numbers. Free. Two minutes.

IHT calculated at 40% above the nil-rate band (£325,000 per person, £650,000 for married couples). Estate freeze locks the value at the point of implementation — all future growth sits outside the IHT net from that date. Figures are illustrative. Your actual position depends on your structure, existing reliefs, and timeline.
What the architecture looks like
Layer 1
The SPV / Trading Layer
Ring-fences liability. Separates properties. Standard. Most investors have this. It is the right first step and nothing more.
Layer 2
The Capital Layer
A family investment company or holding structure that receives rental income and capital gains at a lower tax rate, and begins the process of moving value outside the estate.
Layer 3
The Constitutional Layer
Freezer shares, trust instruments, and succession planning that lock the estate at today's value and ensure the next generation can inherit without a taxable event.
A recent client
“I had four SPVs and thought I was structured. The audit showed me a £700k IHT exposure I had no idea existed. Within three months the estate was frozen at today's value. Everything built from that point sits outside the IHT net permanently. My accountant had never raised it once.”

Who this is for
You have a property portfolio worth £1m or more
The IHT exposure at this level is significant enough to justify the architecture. Below this threshold, the cost of implementation may not be proportionate.
You have one or more SPVs
You have already taken the right first step. The audit shows you what the next two steps look like and what they would cost to implement.
You have not had a full estate planning review
If your accountant has never modelled your IHT exposure in writing, you do not know your position. The audit does this in two minutes.
You are thinking about succession
Whether you want to pass the portfolio to children, a partner, or a trust, the architecture needs to be in place before the conversation happens. Not after.
The only question
The audit maps your property structure across all three layers, calculates your IHT exposure in real numbers, and shows you precisely where the gap is. Free. Two minutes. No sales call required unless the numbers suggest one is worth having.
