The Ledge
The brief
rendered · rev AA country house on a south-facing slope in the Peak District, under one continuous curved shell. Larch runs up from a gritstone base and over the bend into a copper crown. In the middle, a heated garden under glass, with a roof that slides open to the sky.
This is Option B of the Glass Garden House, called The Ledge: plans, elevations and form, rev H, 31 October 2026. Plans are concept-stage and drawn at roughly 1:200. Room sizes are internal and rounded.
the idea
From the drive the house gives nothing away. The north face is a closed curve of larch over a stone wall, with narrow slots and a single oak door. You step through it and see the garden first, then the lounge window and the valley beyond it.
The house is almost square in plan, about 28 m long and 27 m deep, broad and low. Two wings run east to west either side of the garden. The north wing is the practical side, in birch and terrazzo. The south wing is the fun side, in walnut and wool. A slim steel and oak bridge crosses the garden at first floor level, through the canopy of the trees.
Over the middle of the garden, three glass panels run on rails along the ribs. Open, they telescope north and stack over the guest wing, so the glass never blocks the view side.
Rev H matches the drawings to the first good render: a soft 0.5 m overhang at the ends, the copper starting lower on the curve, and a tall narrow oak-finned window at the east end. The 3D model and every drawing come from the same set of numbers.
the brief
| Topic | Decision |
|---|---|
| Outside | Untreated vertical larch. Runs up and over the curve, weathers silver |
| Practical side | Birch and terrazzo. Light, bright, crisp |
| Fun side | Walnut and wool. Charcoal wool, bronze details |
| Garden | Stone flags, heated. Trees, rill, dining, fire |
| Bridge | Slim steel and oak. Glass balustrade, through the canopy |
| Lifts | One per wing. Every bedroom step-free |
| Main suite | Dressing, view bath, garden window. Private terrace cut into the roof |
| Lower ground | Cinema, bar, wine, games, plant. Walnut stair down from the lounge |
the shape
| Part | Decision |
|---|---|
| Form | Gentle saddle with a pinched waist: 8.5 m over the garden, about 10.5 m at the ends, soft 0.5 m overhang |
| Crown | Copper, left to patina, from about 70% of the shell's height. Brown within a year, green over decades |
| Sides | Untreated vertical larch between the stone and the copper. Weathers silver |
| Base | Gritstone walls: 1.2 m on the north, a 0.45 m window-seat upstand on the south over the plinth |
| Ends | Coursed gritstone gables under the overhang. West window 4.5 × 7 m, east window 2 × 8 m behind oak fins, both switchable glass |
| Openings | Deep oak frames for both ribbons, all the north slots, the front door and the garage doors |
| Garage | Stone car barn: gritstone, a small copper saddle roof, bronze clerestory, oak doors, and a larch-lined gallery to the boot room |
| Landscape | A wildflower bank and dry stone wall on the approach, a flagged path, a gravel court, copper rain chains into stone troughs |
The copper starts brown and goes green over decades. The larch goes silver. The house will look different in 20 years, on purpose.
the parts
- Lower ground, 203 m². Under the fun wing: games room, foyer bar and wine room, an eight-seat cinema and the plant room.
- Ground floor, 496 m², plus the 205 m² garden. Office 1, living, kitchen, back kitchen and boot room on the practical side. The double-height lounge, office 2 and the gym on the fun side. A fire room at the west end, a garden store at the east.
- First floor, 323 m². Three guest suites on the practical side. The main suite on the fun side, with a spiral stair from the dressing room to a terrace sunk into the roof.
Each floor has its own page, and so does each elevation, the roof and the two sections. The five rooms that have been rendered have a page each. The model screenshots and the render kit have pages too.
areas
| Part | Area |
|---|---|
| Lower ground | 203 m² |
| Ground floor, excluding the garden | 496 m² |
| First floor | 323 m² |
| House rooms, three floors | 1,022 m² |
| Heated garden under glass, 20 × 10 to 12 m | 205 m² |
| Stone car barn, 8.0 × 7.0 m | 56 m² |
| Gallery link, coats and boots | 10 m² |
| Roof terrace, about 3 × 6 m | 18 m² |
Gross area including walls will be roughly 10 to 12% higher, so about 1,130 m² of house plus the 205 m² garden. That is bigger than the 850 m² in the first options, mainly because of the lower ground floor and the two lift cores.
what it costs
A working estimate from UK benchmarks, not a quote: about £6.2m to £8.0m before fees.
| Item | Range |
|---|---|
| House, about 1,130 m² gross at £4,000 to £5,000/m² | £4.5m to £5.7m |
| Retracting curved glass roof, drive and seals | £0.8m to £1.2m |
| Garden: trees, water, heating, dehumidification | £0.3m to £0.4m |
| Cinema fit-out and AV | £0.15m to £0.25m |
| Two lifts, excavation and retaining walls | £0.4m to £0.5m |
| Indicative build total | £6.2m to £8.0m |
Fees (10 to 15%) and contingency (10% or more) sit on top. The easiest savings if needed:
- Drop the north wing lift and keep a shaft for later. About £80k.
- Shrink the fire room and store ends from 4 m to 3 m. About £0.2m.
the renders
Fourteen AI renders made from screenshots of the 3D model, so details drift. The drawings are the reference. Each prompt and the screenshot it was given are in the render kit.
- South-east, summer evening. The cover. The shell sits low in the meadow and the depth shows in the wide stone end. The east window has lost its fins.
- Arrival, morning. The closed north face, the flush door and the car barn on the court. The east window is wrong, and there is a fire behind it.
- West end, sunset. Close: the stone gable with the fire just inside the window.
- Aerial, roof open. The garden is open to the sky. The glass is one row rather than three stacked panels, and the waist does not pinch.
- In the garden, roof open. The rill, the olive, the maple, the long table and the bridge, with the fire in the foreground. The wings have straight timber eaves instead of the curved shell.
- Lounge. Close: the curved walnut ceiling and ribs, the window seat to the valley and the stone gable.
- Kitchen. Close: birch and terrazzo, with the sliding wall onto the garden table.
- Main suite. The stone bath is at the window, but the bed is turned side-on to the view.
- Cinema. Close: cognac leather, charcoal wool and bronze, with the wine room beyond.
- Night from the valley, late autumn and winter. The window bands and the garden glow, but the whole shell is clad in copper and the larch is lost.
- West end at night. Close: the fire and the garden through the window, with lanterns on the terrace.
- South-east, first take. The take that set the softer ends, the lower copper line and the finned east window.
Any further renders should restate the larch sides between the stone and the copper, the narrow finned east window, the curved shell over the garden, and the car barn's small saddle roof.
