Town centre office building to be used for flats

Reading Borough Council has approved plans to convert the vacant Beta Building on Kings Road—built in the early 1990s and sold earlier this year by Worthing Borough Council to Beta Reading Limited—into 44 flats. The decision, alongside a separate October 2024 approval to convert adjacent Kennet Place into 93 flats, signals local council support for repurposing empty office stock into residential units, modestly increasing housing supply and creating a near-term development pipeline for local property investors and developers.

Analysis

Market structure: This small-but-visible conversion (Beta + Kennet = ~137 flats) signals an accelerating micro-trend: town-centre offices being recycled into residential stock. Winners are conversion specialists, regional housebuilders and building-material suppliers; losers are pure-play office landlords/REITs (e.g., BLND, DLN, WKP) facing longer vacancy tails and weaker pricing power. Locally this could boost housing supply enough to cap rents by an estimated 2–5% in the Reading catchment over 12–24 months while modestly widening commercial credit spreads.

Risk assessment: Tail risks include a financing squeeze if UK 10y gilts rise >75bps (making conversions uneconomic), abrupt planning/regulatory reversals, or >15% construction-cost inflation. Immediate market impact is negligible (days); meaningful effects arrive in 3–12 months (contracts, starts) and fully materialise over 2–5 years (office repricing). Hidden dependencies include parking, remediation costs and affordable-housing levies that can erode IRRs.

Trade implications: Tactical trades: overweight UK regional housebuilders and contractors tied to conversions and underweight office-heavy REITs. Use relative-value pairings (long PSN, short BLND) and volatility strategies: buy 12-month call-spreads on PSN and buy put-spreads on BLND/DLN to cap premium. Rotate ~5% portfolio weight from commercial-REIT exposure into residential developers/materials over 1–3 months; reassess at 12 months or on confirmed starts.

Contrarian angles: Market may underprice conversion capex — typical retrofit costs £50k–£150k/unit can compress returns and slow deals, so benefits to housebuilders may be smaller than headline consent numbers imply. Historical parallels (post-2008 office-to-resi waves) show material execution risk; monitor local planning consents and start notices quarterly as the true leading indicator.

Key Decisions for Investors

• Establish a 2–3% portfolio long position in Persimmon (PSN.L) over 6–12 months, financed by a 1–1.5% short in British Land (BLND.L); target relative return 8–15% and set stop-losses at 20% on the long and 15% on the short.
• Initiate a 1–2% long allocation to Morgan Sindall (MGNS.L) or Galliford Try (GFRD.L) to capture retrofit/contracting wins; hold 6–18 months and trim if UK construction cost index rises >10% YoY.
• Buy a 12-month put-spread on BLND (e.g., 1x 0.8/0.6 notional) with strikes ~-15%/-25% as downside protection against commercial re-pricing; fund by selling 12-month call spreads on PSN (caps upside, reduces premium).
• Reduce direct exposure to office-centric REITs (BLND, DLN, WKP) by ~5% of portfolio weight over the next 1–3 months and redeploy into residential developers and building-material names (e.g., CRH, BREE.L); reassess after 12 months or if UK 10y gilt yield falls >50bps.
