Browse 13 looks for the air well of a terrace or the internal courtyard of a semi-D or bungalow, then see what each one involves.
📍 We serve KL, Selangor & Putrajaya.
An air well or internal courtyard is the open-to-sky space inside the footprint of the house: the narrow light well in many terraces and the larger courtyard at the heart of some semi-Ds and bungalows. It brings daylight and air into the middle of the house, so the design choices are about keeping it open, covering it, or planting it, and about rain: where the water falls, where it drains, and which plants survive the mix of rain and shade. These 13 concept designs show air wells and courtyards in modern, tropical and zen styles, both open to the sky and covered. Use the filters below to narrow them by style, open or covered, or home type.
Each design below is an illustrative concept render of one air well or courtyard idea. They are grouped by style, by open or covered, and by home type. Tap any image to enlarge it. Every card links to the ClickBina guide that covers the work behind that look.

landscape designs →These are illustrative concept designs created to show courtyard and air well options. They are not completed ClickBina projects. We refit air wells and courtyards as part of our renovation and landscape work, and your house is assessed and quoted to its own layout, drainage and building rules.

Decide first whether it stays open. An open air well brings the most light and air into the house, but also rain, leaves and sometimes animals. A covered one stays dry and can become usable floor, but it can trap heat. Many owners keep it open and plant it, or cover it with a roof that still lets air move.
ClickBina's air well renovation guide explains whether to cover, enclose or keep an air well open; this gallery shows what each choice can look like.
| Option | Light and air | Rain | Watch for |
|---|---|---|---|
| Open, planted | Most light and airflow | Falls straight in | Drainage and plants that cope with storms |
| Clear polycarbonate cover | Good light, less air | Kept out | Heat build-up and dirt on the sheets |
| Glass roof with louvres | Good light, some air | Kept out | Heat; cost of a custom glass roof |
| Retractable fabric roof | Shade when needed | Light rain only | Must be retracted in storms |
| Grille or mesh over the top | Unchanged | Falls in | Leaves on the mesh need clearing |
| Fully enclosed as a room | Least | Kept out | Ventilation and building approvals |
| Your house | Usually works | Watch for |
|---|---|---|
| Terrace with a narrow air well | Tree in pebbles, rain chain drain, clear cover with ferns | Roof run-off and the floor trap |
| Semi-D with a side courtyard | Planting seen from the dining room, bamboo behind glass, edge bench | Drainage along the boundary wall |
| Bungalow with a central courtyard | Deck, koi trough, single tree, glass roof with louvres | Heat under glass and pond filtration |
| Older house with a damp air well | Better drainage, a clear cover, hardy ferns | Damp in the surrounding walls |
The pieces of a courtyard have their own guides. The polycarbonate roofing guide covers clear covers, the skylight cost guide covers glass roofs, and the koi pond cost guide covers ponds with filtration.
For water features without fish, see the garden pond and water feature guide; for a courtyard that floods, the garden drainage guide explains falls and drains.
Covers have published ranges. ClickBina's air well guide cites a small fixed polycarbonate skylight at RM1,500 – RM3,500 installed, a small fixed glass skylight at RM3,500 – RM7,000 and a large custom glass roof at RM15,000 – RM35,000 (indicative Klang Valley ranges for 2026).
For water, the garden pond guide puts a basic small decorative pond at RM8,000 – RM15,000, and the koi pond guide puts a mid-size pond with proper filtration at RM15,000 – RM35,000. For floors and shade, the decking guide prices basic-to-mid WPC at RM30 – RM60 per sq ft installed, porcelain tiles run RM18 – RM35 per sq ft supplied and laid on the pebble wash guide, and a retractable fabric roof is about RM400 – RM900 per metre run on the awning guide.

Glass roofs and ponds with filtration are quoted as their own items, and any enclosure follows your council's rules.
