The Smart Alternative

Why Move, When You Can Elevate?

The average UK homeowner spends £15,000–£30,000 on moving costs alone — agent fees, legal costs, removals and more. A well-planned extension or loft conversion gives you the space you need while adding significantly more value than it costs to build.

  • Internal connection to main house
  • Wide range of finish specifications

Room Additions &

  • Internal wall removals and structural alterations
  • Add a bedroom, study, or home office
  • Open-plan reconfiguration — kitchens, living, dining
  • Floor plan redesign to improve flow and light

01
Free Consultation

03
Planning Permission

In most cases planning permission will have been obtained before we get involved. This is normally arranged by the client or their architect as part of the design process. We are happy to advise and support where we can.

Please Note
Planning is typically sorted prior to engaging Brookstone — we can advise if needed
04
Build & Construction

With planning secured, we get to work. Delivering quality you can see and feel across every stage of the build. Regular updates keep you informed every step of the way, and a clear payment schedule is agreed upfront so there are no surprises.

The Investment Case

Why Extensions & Conversions
Outperform the Market

In a challenging market, savvy investors turn to extension and conversion projects as a reliable route to creating significant uplift in both capital value and rental income — without the risk of buying at peak valuations.

Capital Value Creation
A well-designed loft conversion or extension can add 10–20% to your property's value — a significant return that often far exceeds the cost of the works themselves.
Rental Income Uplift
Adding a bedroom can increase rental income by 15–30%. Converting to an HMO layout with additional rooms can increase rental income by 20–50%, significantly improving your yield.
Portfolio Development
Whether you own one investment property or several, we work with you to identify the improvements that will deliver the strongest return on your specific assets.
Fixed Price Certainty
Every project is agreed at a fixed price before we begin. No hidden costs, no budget surprises — giving you the financial certainty you need to plan your investment with confidence.
