Topwood Swift Summerhouse
The Topwood Swift is a charming chalet‑style summerhouse designed to bring warmth, character and year‑round enjoyment to any garden. With its distinctive wavy fascia roofline, extended 22″ roof overhang and welcoming double‑door frontage, it has a relaxed, holiday‑cabin feel that makes it an inviting retreat for reading, crafting, working or simply unwinding outdoors.
Generous glazing across the front and sides fills the interior with natural light, creating a bright, uplifting space that feels just as cosy on a crisp spring morning as it does on a summer afternoon. The Swift’s timeless chalet aesthetic blends beautifully into both traditional and contemporary gardens, offering a versatile escape just steps from home.
Hand‑built in the UK from high‑quality Scandinavian redwood pine, the Swift features 12mm tongue‑and‑groove shiplap cladding, a matching T&G floor and roof, and sturdy 2″ x 1.5″ framing — delivering the same dependable strength and longevity found across the entire Topwood collection. Glazed double doors, fixed front windows, and 4 opening side windows with vents, complete the look, ensuring durability and long‑lasting appeal.
Available in a range of sizes, the Swift can be tailored to suit your garden and your style. Optional upgrades include installation (location dependent), factory treatment, heavy‑duty cladding, loglap, EPDM roofing and more — allowing you to create a summerhouse that’s both beautiful and built to last.

Premium Redwood Construction
Topwood buildings are crafted from Scandinavian Redwood Pine, a slow‑grown, denser timber that naturally offers greater durability and stability than cheaper whitewood alternatives. This means:
- Less seasonal movement
- A stronger, longer‑lasting structure
- A more premium finish
Redwood (if not pressure treated) requires annual maintenance with a solvent based preservative applied to the outside of the building every year – Add Pressure Treatment + Solvent Treatment to your order, to lower maintenance to every 6 – 8 years!
Redwood has a desired service life of 25 years + with suitable maintenance.
Colour varies depending on treatment applied.

Guarantee
Topwood Garden Buildings come with a 12-month guarantee against faulty parts and workmanship, and 10 years against wood rot, providing the building is treated & maintained on a regular basis from the time of supply.
Treatment options available:
Pressure Treated & Solvent Treatment
Pressure treated timber is pressure treated by being held in a vacuum and impregnated with a preservative solution. This offers longer lasting protection against wood rot, fungal disease & insect attack.
Pressure treated timber is a low maintenance option – Once the timber has had its initial coating of a solvent based wood preservative (or a suitable wood protective coloured paint), the building will only need to be treated again approximately every 6 – 8 years, rather than on an annual basis. We can offer the first initial solvent treatment prior to delivery – please see price list.
Pressure treated timber has a light green/yellow colouration (if not solvent treated), and a desired life in excess of 25 years with suitable maintenance.
** Please note all pressure treated featheredge buildings must also be solvent treated due to higher moisture content.**
Solvent treatment (wood preservative) protects against wood rot and fungal disease and seals the building against moisture ingress. We recommend that this is applied as soon as possible after installation, although Pressure treated buildings will benefit from a few weeks before treatment or paint is applied, to allow the moisture levels in the timber to reduce, leading to a better finish.
Installation & Base Requirements
We offer installation on Topwood buildings (location dependent), giving you a stress‑free experience from start to finish.
To enable installation, your building must sit on a flat, level, firm base made from paving slabs or concrete. The base should:
- Match the size of the building (can be larger, but never smaller)
- Be completely flat & level to a spirit level standard, with no drainage slope
- Sit at least 2 inches above ground level to avoid ground water running underneath
For larger bases or restricted airflow, please refer to our guidance on bearers.
** It is the customer’s responsibility to provide a suitable base for their building, with clear and safe access **
Bearers can be added to your order at an additional cost. Bearers are pressure treated / tanalised timbers that raise a shed up off the ground to prevent the floor from getting damp and rotting. They need to be laid on flat, level, compact ground (or on top of level paving slabs/concrete). Bearers should be used if the base is larger than the footprint of the building, or if there is restricted airflow around the building, (i.e. a fence or wall very close to the shed) to avoid rain water building up and sitting against the floor of the building.
Clearance
We recommend 18″ clearance around the building for installation, airflow, and future maintenance. Topwood can work with as little as 8″ clearance as a minimum, but this must be stated on the order.
