Café and restaurant renovation in Riga

Kitchen and washing area

In the kitchen and the dishwashing area, the floor and walls can be tiled. In wet zones, waterproofing is applied before tiling: the manufacturer intends Ceresit CL 51 for waterproofing walls and floors in wet rooms, including kitchens, and recommends at least two coats so that the dry layer is 0.5 mm. Waterproofing tape is worked into the joints between wall and floor, and collars are used around pipes and drains.

The Ceresit CM 17 tile adhesive data sheet requires the adhesive to cover at least 65% of the underside of the tile, and joints in corners, at the floor and at plumbing fixtures are filled with silicone, not grout. For CE 40 grout, the manufacturer states water exposure after 24 hours and full strength after 5 days; for the first 5 days it is washed only with clean water. This has to be considered when planning when the café reopens.

Gas and ventilation

A gas cooker can be replaced or moved within one room in agreement with the gas supplier (LBN 241-15, paragraph 7). An appliance with a flue, even in the same room, needs the supplier's permission and a report on the condition of the flue and ventilation ducts (paragraph 8). Moving a gas appliance to another room or installing a new appliance needs the gas supplier's technical conditions, a report on the flue and ventilation ducts and a building design (paragraph 9). The technical solution for moving gas pipes is prepared or approved by a certified person. Gas work is not part of the renovation estimate.

The Fire Safety Regulations currently in force prohibit using a natural ventilation duct or mechanical ventilation to discharge flue gases. The ventilation system is designed and installed separately; in the finish, the ducts and hatches must remain accessible.

Dining room for visitors

In the dining room, the walls and ceilings, the floor covering and the lighting can be renovated. For the walls, painting from €4/m² or decorative plaster application from €30/m² is suitable. In the ceiling, plasterboard can hide wires and ventilation ducts; plasterboard or suspended ceilings are from €15/m². For a floor with heavy foot traffic, tiles or vinyl flooring are chosen.

If the use of the premises changes

Under the Building Construction Regulations, simplified renovation means improvements that do not change the load-bearing structures, the volume and the type of use. If a café is set up in premises that were previously a shop, an office or an apartment, the type of use changes, so find out from the building board or the designer which documents are needed before the renovation. In Riga the functions of the building board are carried out by the City Development Department (Pilsētas attīstības departaments).

How much does a café renovation cost?

Prices are for labour. Materials are calculated separately in the estimate. For a café or restaurant renovation the total price is by estimate, drawn up from the prices of individual jobs: tiling from €24/m², demolition of old tiles from €9/m², plasterboard or suspended ceilings from €15/m², painting from €4/m², an electrical point from €12 per point.

Example: a kitchen floor of 20 m². Demolition of old tiles 20 × €9 = €180 and tiling 20 × €24 = €480, in total from €660 for these two jobs. The price is affected by the area, the condition of the walls and floors, whether the pipes and electrical wiring are changed and the chosen finish. All prices: apartment renovation prices.
