We’re delighted to announce that planning consent has been granted for an elegant new detached pool-house and spa together with comprehensive landscaping at our client’s home in the heart of Beaconsfield, Buckinghamshire. This bespoke addition builds on the existing residence to deliver a refined wellness sanctuary and an extension to the family’s living spaces.
Located just outside London, the site presents a generous garden setting where our team at Watershedd Architects & Interior Designers have conceived a linear, low-profile pavilion that sits neatly alongside the garden edge. With a 150 m² footprint and a targeted completion in 2026, the pool-house introduces an indoor lap pool, spa, sauna and changing area — all wrapped within a form that speaks quietly of luxury, calm and connection to the landscape.
Design-wise, the building works as a contemporary extension to the main house, yet is conceived as a standalone retreat. The long, narrow plan lies parallel to the garden perimeter, defined by slim structural lines, generous glazing and a living green roof that gently merges into the tree-canopy beyond. The outward-facing sides open to the garden so that water, greenery and light knit together to create a sense of stillness and retreat.
Inside the wellness wing, the palette has been deliberately restrained to elevate atmosphere over ornament. Deep green tiles line the pool basin, referencing the woodland beyond. Timber ceiling beams introduce warmth and a gentle rhythm. Hand-laid cobbles underfoot and pale stone walls continue into the landscaping outside, promoting a tactile relationship between interior and exterior. Full-height glazing invites daylight into the space, the water surface reflecting shifting light across calm surfaces.
Externally, the façade uses pale buff linear brickwork to complement the muted tones of the main house, ensuring a cohesive transition between the existing and the new. The landscaping around the pool-house is comprehensively designed: from a sunken fire-pit lounge to an outdoor dining terrace and private reflection zones, the gardens have been configured as a sequence of experiences — gathering, relaxation, wellness.
For our clients, this pool-house is far more than an out-building — it’s a meaningful investment in lifestyle, bringing together form, function and environment. It adds a dedicated wellness facility to the home, whilst also extending the family’s informal living and entertaining spaces beyond the original house footprint. In effect, it changes how the garden is used, and how the home is lived.
We’re excited to begin the next phase — detailed design, coordination and eventual construction — and look forward to working with our client, the planning authority and contractor to bring this house extension to life. Stay tuned for further updates as the project progresses.
