Market Penetration
Castellum is using market penetration to squeeze more value from its 5.5 million sqm portfolio, rather than buying new assets. In its Stockholm, Gothenburg, and Malmo CBD hubs, it targets a lift in stabilized occupancy from 90% to 93% by mid-2026, using tenant retention and lease renegotiations to capture current market rents. A 3-point occupancy gain on 5.5 million sqm equals roughly 165,000 sqm of extra leased space.
Castellum has linked CPI clauses to about 95% of its leases, so rent rises with inflation and helps protect net operating income. This builds a steady buffer against higher operating costs, while keeping cash flow more predictable in 2025 and 2026. Management expects these indexations to add about 3% to annual like-for-like rental growth.
Castellum's SEK 2.5 billion disposal program in non-core assets is classic market penetration: sell older, weaker properties and recycle capital into higher-yielding offices in core Nordic cities. In 2025, that keeps the portfolio tighter, lifts average asset quality, and supports the same local markets where Castellum already has scale.
The move also helps lower loan-to-value without relying on expensive new equity or debt, which protects returns in fiscal 2026.
Expanding the 'United Spaces' co-working brand within existing properties
Castellum is deepening market penetration by converting traditional office floors into flexible United Spaces coworking space inside existing buildings. That lifts square-meter revenue density in high-demand Swedish metros and fits hybrid work demand, which keeps smaller tenants in the mix. By March 2026, United Spaces should cover about 15% more of Castellum's owned CBD square footage than two years earlier.
Optimizing digital twin technology across 40 percent of total floor space
Castellum's market penetration play is to scale building management systems and digital twins across 40% of total floor space, using existing assets to win share from older, unmanaged peers. The rollout supports lower vacancy by improving environmental performance and cutting service charges, while management estimates about 7% lower operating expense per square foot. That cost gap matters in 2025, when ESG-focused tenants are still paying a premium for low utility costs and stronger building data.
Castellum's market penetration centers on lifting occupancy in its 5.5 million sqm portfolio, with a 90% to 93% target in core Nordic hubs and about 165,000 sqm of extra leased space. CPI-linked leases on about 95% of contracts and a 3% like-for-like rent boost support 2025 income. Its SEK 2.5 billion disposal plan and United Spaces rollout deepen share in existing markets.
| Metric | 2025/2026 |
|---|---|
| Portfolio | 5.5m sqm |
| Occupancy target | 90% to 93% |
| CPI-linked leases | 95% |
| Disposals | SEK 2.5bn |
What is included in the product
Market Development
Castellum's move into the Helsinki and Oulu corridors shifts growth beyond Sweden and into Finland's e-commerce-led logistics demand. The plan targets 50,000 square meters of high-spec hubs, built to support Nordic distribution flows. A 12 percent share of the local prime logistics market would give Castellum a clear foothold in a tighter, more specialized segment.
Castellum's market development here is to buy public-sector leases in Tier 2 Swedish cities like Luleå and Skellefteå, where industrial growth supports demand for offices, schools, and civic space. Long leases of 10 to 15 years from government agencies and educational bodies can reduce vacancy risk versus shorter corporate contracts. This widens cash flow sources while staying inside Castellum's core property management skill set.
Castellum is deepening its foothold in Greater Copenhagen by buying and upgrading lab-ready assets for biotech tenants. That raises exposure to a high-entry-barrier niche where regulated fit-out, power, and HVAC matter more than standard office space. By March 2026, specialized life-science tenants are expected to generate over 8 percent of the Danish portfolio's rental value, which supports more stable, specialized cash flow.
Launching a specialized small-business warehouse model in regional hubs
This market development extends Castellum's industrial park model into 5 regional logistics nodes, targeting local distributors that large institutional developers often skip. The smaller 5,000-square-meter modular units fit fragmented demand and reduce dependence on a few metro hubs, which helps spread occupancy and rent risk across more markets.
It is a clear Ansoff market-development move: the product is familiar, but the geography is new.
Forging joint ventures to enter the sustainable industrial sector
By partnering with green-tech manufacturers, Castellum is moving into the sustainable industrial sector through bespoke sites in northern Scandinavia for fossil-free steel and battery production. The 20-year net-lease structure gives Castellum long, stable income while reducing tenant default risk, and it opens industrial markets outside its core office and logistics base. This is a market-development move that pairs entry into emerging industrial hubs with a major development partner.
Castellum's market development stays close to its core skills but moves into new Nordic geographies and tenant pools, from Finnish logistics corridors to Swedish public-sector hubs and Danish life-science clusters. The common pattern is familiar assets, longer leases, and lower vacancy risk: 50,000 sqm in Finland, 10-15 year public leases in Sweden, and over 8% of Danish rental value from life science by March 2026.
| Move | 2025/26 signal |
|---|---|
| Finland logistics | 50,000 sqm |
| Swedish public sector | 10-15 year leases |
| Danish life science | >8% rental value |

Product Development
Castellum's 100 MW rooftop solar rollout turns idle roofs into revenue assets, selling power to tenants and lowering grid purchases. In Nordic conditions, 100 MW can produce about 90-110 GWh a year, so reaching 20% of internal demand by early 2026 is plausible if load is near 450-550 GWh. Better energy scores can also lift values, with green-certified assets often earning 3%-8% rent premiums.
Castellum's "Smart Office" subscription shifts Product Development toward Workplace as a Service: tenants lease fully equipped space, not just square meters. The model captures more of the value chain and fits tech tenants' demand for faster move-ins and lower capex. In Stockholm, adoption has already reached 25% among new technology-sector tenants, showing early traction.
Castellum's hybrid wood-and-concrete office product targets net-zero demand by using cross-laminated timber, which cuts embodied carbon and improves indoor climate quality. These assets can earn about a 10% rental premium versus standard offices, helped by stronger appeal to multinational tenants. By March 2026, three flagship timber projects are expected to finish, giving Castellum a live proof-of-concept for the Nordic office market.
Introducing data-as-a-service for retail and logistics tenant optimization
Castellum's data-as-a-service push adds a 2025-style digital layer to its logistics assets: a proprietary analytics platform gives tenants real-time footfall and shipment-throughput data to tighten operations inside leased space. That turns the landlord relationship into a 2-tier offer, where rent is paired with high-margin insights that support supply-chain speed and space use. For data-driven retailers and logistics firms, Castellum becomes more than a landlord; it becomes a performance partner.
Establishing the 'Wellness Office' certification program for high-tier properties
Castellum's "Wellness Office" certification turns premium offices into a product for 2026 hiring wars, as employers use workplace quality to attract staff. The standard can bundle advanced air filtration, light optimization, and green interiors that go beyond code, helping justify higher rents in top-tier buildings. This fits the 2025 market, where office users are paying more for space that supports health, focus, and retention.
Product Development at Castellum means adding higher-value services to existing properties: Smart Office, data analytics, wellness features, and low-carbon materials. These moves aim to lift rent, tenant stickiness, and asset value in a 2025 market where green-certified offices often get 3%-8% rent premiums. The clearest proof is the 100 MW solar rollout, which can generate about 90-110 GWh a year.
| Move | 2025-26 signal |
|---|---|
| Product Development | Higher rent, lower carbon, stickier tenants |
Diversification
Castellum's SEK 500 million push into battery storage at property perimeters is a clear Ansoff diversification move: it adds energy infrastructure to a core real-estate base. The 4 flagship sites can create a less correlated cash flow than rent, because grid-balancing revenue depends on power prices and system demand, not just occupancy. If returns are 200 bps above traditional rents, the spread shows why this can lift portfolio yield and reduce reliance on brick and mortar.
Castellum has widened its capital base by backing prop-tech firms in real estate automation and robotics, giving it equity exposure to faster-growth software while also improving its own operations. Its portfolio of 12 strategic investments acts as a hedge against property-cycle risk and a live test bed for new tools. In Ansoff terms, this is diversification: new products, new tech, and a new return stream.
Castellum's purchase of district heating assets in southern Sweden is a diversification move that turns the Company from a pure property owner into a local utility operator. By owning heat and cooling networks, Castellum can cut tenant exposure to utility price swings and also earn third-party energy sales, matching its 3-year shift toward an integrated infrastructure model.
Establishing a carbon credit platform based on reforestation of land reserves
Castellum's carbon-credit platform uses peripheral land reserves for reforestation and carbon sequestration, turning undevelopable acreage into a tradeable offset asset. This is diversification through product development, because the company is creating a new revenue stream from land already on hand. Management expects external credit sales to add 2% to the bottom line by 2027, while also strengthening ESG appeal for green investors.
Launching the 'Castellum Ventures' fund for senior living infrastructure
Launching "Castellum Ventures" is a diversification move into senior living infrastructure, targeting the fast-growing 65+ market while reusing Castellum's urban planning skills. The World Health Organization says the 60+ population will reach 1.4 billion by 2030, so demand for age-friendly housing is rising fast. Pairing senior communities with co-working hubs also widens tenant income streams and supports social-impact real estate.
This pivot can fit 2026 social-bond financing, where investors favor assets tied to measurable care and community outcomes. The intergenerational model adds a new customer base without leaving Castellum's core city-led development playbook.
Castellum's diversification is moving beyond rent into energy, tech, and social infrastructure, so cash flow is less tied to office occupancy. The SEK 500 million battery-storage buildout at 4 sites adds a new revenue stream, while 12 strategic prop-tech bets and district-heating assets widen the return base. This lowers property-cycle risk and can lift portfolio yield.
| Move | 2025 | Why it matters |
|---|---|---|
| Batteries | SEK 500m | New energy cash flow |
| Prop-tech | 12 stakes | Tech upside + hedge |
Frequently Asked Questions
Castellum mitigates financial risk by maintaining a strict loan-to-value ratio below 50 percent as of March 2026. The company successfully migrated 85 percent of its debt into fixed-rate structures or bank-syndicated facilities. These 2 metrics provide significant protection against volatility, ensuring the property portfolio remains resilient during periods of economic transition and tighter capital conditions.
