Walsall

In this record
We refurbished a prominent 1920s building in the heart of historic Walsall, developing a residential scheme in vacant office space that exceeded market expectations.
The asset, a four-storey mock Tudor building with a terrace of four ground-floor retail units, was obtained with vacant possession of the upper parts.
The retail units were fully let and producing an excellent return.
Having conducted thorough due diligence on the Walsall housing market at the time of purchase, we could see there was good value to be made in the vacant offices.
Walsall was undergoing a period of regeneration, and our residential scheme was targeted at young West Midlands professionals looking for their first home, allowing them to live outside of the city centre and commute into Birmingham, taking advantage of the more cost-effective property market in Walsall.
We refurbished the offices into an 18-flat development, creating an attractive product that sold exceptionally well.
We offered various effective financial incentives to swiftly sell the 18 units to our target demographic, at prices in excess of 50% higher than local property professionals had said we could achieve.
This strategy also strengthened the retail investment by removing the draining empty rates from the vacant office space.
Following the successful sale of the residential portion of the asset, we then sold the retail units, exiting the 18-month project with a considerable profit for our clients.

We converted empty offices above Tudor House into eighteen homes, exiting an 18-month project at a considerable profit. Underused space often holds the best of an asset's potential.

Key insights
Real estate sits alongside equities, private equity and fixed income in most family office portfolios – but it behaves differently to all of them, and that's exactly why it earns its place.
Real estate is one of the core asset classes in most family office portfolios, alongside public equities, private equity, fixed income and increasingly private credit. Family office asset allocation to real estate has grown in recent years, driven by its long-term yield, its role as a diversifier against public markets, and its suitability for multi-generational holding periods that few other asset classes match.
Family offices typically hold a mix of private equity and direct investments, real estate, public equities, fixed income and alternative investments, with the exact split varying by size, generational stage and risk appetite. Real estate tends to justify its place in that mix for reasons other asset classes don't share: a steady, long-term income yield; a long holding horizon that matches how families think about multi-generational wealth; and enough direct control that a family can shape an asset's performance rather than simply hold a position and wait.
Once real estate earns its place in the allocation, there's a separate question of how to access it – directly, or through a fund or REIT structure. That decision affects fees, control and liquidity in more depth than an allocation discussion needs to cover; the trade-offs are set out in full in our guide to financial planning for property investment. What matters at the allocation level is simpler: direct ownership is what lets a family actively shape a property's performance rather than passively hold a position in it, which is a large part of why real estate earns a place in the portfolio in the first place.
Discovery Park in Kent is a clear illustration of what that control can achieve. Brought under active management, the science park's capital value grew from around £20m to more than £75m over two years – restructuring leases and separating out service charges rather than simply holding the asset and waiting. A passive fund position, with no say over how the asset is run, couldn't have delivered the same outcome.
UK real estate remains a core allocation, but the mix within it is shifting. Portfolios are diversifying into student accommodation, retail parks and leisure assets alongside the more traditional office and residential holdings, and branded hotel and hospitality assets remain in favour where they carry a strong covenant. Family offices weighing new allocations are also factoring in wider considerations earlier than before – joint venture and asset management arrangements, transparency requirements such as the Land Registry's Persons of Significant Control and Overseas Entities registers, and planning and tax implications specific to the deal.
Maritime Capital's own track record reflects the same pattern of diversification: self-storage and leisure conversions such as Storage Box in Hersham, branded hospitality including The Forbury Hotel in Reading and Raithwaite Sandsend in Yorkshire, and retail assets alongside the more familiar office and residential holdings. The common thread isn't the sector – it's a covenant and a business model resilient enough to justify the allocation in the first place.
Few asset classes hold up as well across multiple generations as real estate. A well-managed property can be improved, repositioned and passed down without a fixed exit forced by a fund's term, which matters to families thinking in decades rather than years. That said, realising the benefit depends on active management – a passively held property doesn't generate the same value as one where lease strategy, service charge control and repositioning decisions are being made deliberately.
Hungerford Park shows what that looks like over a genuinely long horizon. Acquired in 2005 as a 300-acre estate, it's been built over two decades into a working farm, a holiday-let business and an events venue – the kind of layered, multi-generational value creation that a fund's fixed term could never accommodate, and that only comes from treating the asset as a long-term project rather than a static holding.
Most family offices don't carry deep in-house real estate expertise alongside their wider investment team, which is why property is often the asset class most commonly brought in through a specialist partner rather than managed entirely in-house. Maritime Capital works alongside family offices and their existing advisers – wealth managers, investment managers and private banks – on the UK commercial property portion of the portfolio specifically, from acquisition through to ongoing asset and property management.
