The Arches Observatory

This elegant but compact 11×7′ observatory was built for a customer on the Welsh coast, and features a small but perfectly formed 3′ warm room as well as a 7′ square observatory.

It includes our signature pent roof, as well as additional exterior windows for both rooms and in the dividing wall.

Another unique feature was the arched braces for the pergola structure, designed at the client’s request.  I’ll admit we weren’t convinced at the design stage, but they lend the end result an air of elegance that I rather like!

The door is our standard hardwood fire-door with tanalised cladding to match the rest of the building, this time with two 5-lever mortice locks for added security.

The whole structure, as usual, sits on just six standard paving slabs, minimising the impact on the garden and ensuring good drainage for a dry environment inside.

The floor in this design is level, and there is plenty of standing height in the warm room, which is made possible partly by the customer’s choice of telescope. The refractor is both narrow and long, allowing the eyepiece to remain at a sensible height whilst the top of the telescope is much higher and yet the roof can still close over the instrument.

Once again, the warm room is fully enclosed and insulated with closed-cell PIR insulation, ensuring an absence of heat plumes and haze whilst keeping the occupant warm and cozy on the coldest of nights.  Our now standard 2-way light system provides independent red and white lights in both the observatory and warm room, the observatory red light switchable from inside the warm room as well as in the observatory itself.

UPDATE – we were very pleased to visit our customer again earlier this year to install an “extension” to his observatory – placing a good sized storage room in the space under the roll-off frame. All our observatories are designed as modules that fit within the frame – so adding (or even removing) a module is no problem at all!  The last picture shows the finished result.
